For the next four years he lived modestly at Turin, devoting himself once more to art, although he also continued to take an active interest in politics, Cavour always consulting him on matters of moment. In 1855 he was appointed director of the Turin art gallery. In 1859 he was given various political missions, including one to Paris and London to prepare the basis for a general congress of the powers on the Italian question. When war between Piedmont and Austria appeared inevitable he returned to Italy, and was sent as royal commissioner by Cavour to Romagna, whence the papal troops had been expelled. After the peace of Villafranca, d'Azeglio was recalled with orders to withdraw the Piedmontese garrisons; but he saw the danger of allowing the papal troops to reoccupy the province, and after a severe inner struggle left Bologna without the troops, and interviewed the king. The latter approved of his action, and said that his orders had not been accurately expressed; thus Romagna was saved. That same year he published a pamphlet in French entitled De la Politique et du droit chretien au point de vue de la question italienne, with the object of inducing Napoleon III. to continue his pro-Italian policy. Early in 1860 Cavour appointed him governor of Milan, evacuated by the Austrians after the battle of Magenta, a position which he held with great ability. But, disapproving of the government's policy with regard to Garibaldi's Sicilian expedition and the occupation by Piedmont of the kingdom of Naples as inopportune, he resigned office.

The death of his two brothers in 1862 and of Cavour in 1861 caused Massimo great grief, and he subsequently led a comparatively retired life. But he took part in politics, both as a deputy and a writer, his two chief subjects of interest being the Roman question and the relations of Piedmont (now the kingdom of Italy) with Mazzini and the other revolutionists. In his opinion Italy must be unified by means of the Franco-Piedmontese army alone, all connexion with the conspirators being eschewed, while the pope should enjoy nominal sovereignty over Rome, with full spiritual independence, the capital of Italy being established elsewhere, but the Romans being Italian citizens (see his letters to E. Rendu and his pamphlet Le questioni urgenti). He strongly disapproved of the convention of 1864 between the Italian government and the pope. The last few years of d'Azeglio's life were spent chiefly at his villa of Cannero, where he set to work to write his own memoirs. He died of fever on the 15th of January 1866.

Massimo d'Azeglio was a very attractive personality, as well as an absolutely honest patriot, and a characteristic example of the best type of Piedmontese aristocrat. He was cautious and conservative; in his general ideas on the liberation of Italy he was wrong, and to some extent he was an amateur in politics, but of his sincerity there is no doubt. As an author his political writings are trenchant and clear, but his novels are somewhat heavy and old-fashioned, and are interesting only if one reads the political allusions between the lines.

Besides a variety of newspaper articles and pamphlets, d'Azeglio's chief works are the two novels Ettore Fieramosca (1833) and Niccolo dei Lapi (1841), and a volume of autobiographical memoirs entitled I Miei Ricordi, a most charming work published after his death, in 1866, but unfortunately incomplete. See in addition to the Ricordi, L. Carpi's Il Risorgimento Italiano, vol. i. pp. 288 sq. and the Souvenirs historiques of Constance d'Azeglio, Massimo's niece (Turin, 1884).

AZERBĀIJĀN (also spelt ADERBIJAN; the Azerbādegān of medieval writers, the Athropatakan and Atropatene of the ancients), the north-western and most important province of Persia. It is separated from Russian territory on the N. by the river Aras (Araxes), while it has the Caspian Sea, Gilan and Khamseh (Zenjān) on the E., Kurdistan on the S., and Asiatic Turkey on the W. Its area is estimated at 32,000 sq. m.; its population at 1-1/2 to 2 millions, comprising various races, as Persians proper, Turks, Kurds, Syrians, Armenians, &c. The country is superior in fertility to most provinces of Persia, and consists of a regular succession of undulating eminences, partially cultivated and opening into extensive plains. Near the centre of the province the mountains of Sahand rise in an accumulated mass to the height of 12,000 ft. above the sea. The highest mountain of the province is in its eastern part, Mount Savelan, with an elevation of 15,792 ft., and the Talish Mountains, which run from north to south, parallel to and at no great distance from the Caspian, have an altitude of 9000 ft. The principal rivers are the Aras and Kizil Uzain, both receiving numerous tributaries and flowing into the Caspian, and the Jaghatu, Tatava, Murdi, Aji and others, which [v.03 p.0081] drain into the Urmia lake. The country to the west of the lake, with the districts of Selmas and Urmia, is the most prosperous part of Azerbāijān, yet even here the intelligent traveller laments the want of enterprise among the inhabitants. Azerbāijān is one of the most productive provinces of Persia. The orchards and gardens in which many villages are embosomed yield delicious fruits of almost every description, and great quantities, dried, are exported, principally to Russia. Provisions are cheap and abundant, but there is a lack of forests and timber trees. Lead, copper, sulphur, orpiment, also lignite, have been found within the confines of the province; also a kind of beautiful, variegated, translucent marble, which takes a high polish, is used in the construction of palatial buildings, tanks, baths, &c., and is known as Maragha, or Tabriz marble. The climate is healthy, not hot in summer, and cold in winter. The cold sometimes is severely felt by the poor classes owing to want of proper fuel, for which a great part of the population has no substitute except dried cow-dung. Snow lies on the mountains for about eight months in the year, and water is everywhere abundant. The best soils when abundantly irrigated yield from 50- to 60-fold, and the water for this purpose is supplied by the innumerable streams which intersect the province. The natives of Azerbāijān make excellent soldiers, and about a third of the Persian army is composed of them. The province is divided into a number of administrative sub-provinces or districts, each with a hākim, governor or sub-governor, under the governor-general, who under the Kajar dynasty has always been the heir-apparent to the throne of Persia, assisted by a responsible minister appointed by the shah. The administrative divisions are as follows:—Tabriz and environs; Uskuh; Deh-Kharegan; Maragha; Miandoab; Saūjbulagh; Sulduz; Urmia; Selmas; Khoi; Maku; Gerger; Merend; Karadagh; Arvanek; Talish; Ardebil; Mishkin; Khalkhāl; Hashtrud; Garmrud; Afshar; Sain Kaleh; Ujan; Sarab. The revenue amounts to about L200,000 per annum in cash and kind, and nearly all of it is expended in the province for the maintenance of the court of the heir-apparent, the salaries and pay to government officials, troops, pensions, &c.

AZIMUTH (from the Arabic), in astronomy, the angular distance from the north or south point of the horizon to the foot of the vertical circle through a heavenly body. In the case of a horizontal line the azimuth is its deviation from the north or south direction.

AZO (c. 1150-1230), Italian jurist. This Azo, whose name is sometimes written Azzo and Azzolenus, and who is occasionally described as Azo Soldanus, from the surname of his father, is to be distinguished from two other famous Italians of the same name, viz. Azo Lambertaccius, a canonist of the 13th century, professor of canon law at the university of Bologna, author of Questiones in jus canonicum, and Azo de Ramenghis, a canonist of the 14th century, also a professor of canon law at Bologna, and author of Repetitiones super libro Decretorum. Few particulars are known as to the life of Azo, further than that he was born at Bologna about the middle of the 12th century, and was a pupil of Joannes Bassianus, and afterwards became professor of civil law in the university of his native town. He also took an active part in municipal life, Bologna, with the other Lombard republics, having gained its municipal independence. Azo occupied a very important position amongst the glossators, and his Readings on the Code, which were collected by his pupil, Alessandro de Santo Aegidio, and completed by the additions of Hugolinus and Odofredus, form a methodical exposition of Roman law, and were of such weight before the tribunals that it used to be said, "Chi non ha Azzo, non vada a palazzo." Azo gained a great reputation as a professor, and numbered amongst his pupils Accursius and Jacobus Balduinus. He died about 1230.

AZO COMPOUNDS, organic substances of the type R.N:N.R' (where R = an aryl radical and R' = a substituted alkyl, or aryl radical). They may be prepared by the reduction of nitro compounds in alkaline solution (using zinc dust and alkali, or a solution of an alkaline stannite as a reducing agent); by oxidation of hydrazo compounds; or by the coupling of a diazotized amine and any compound of a phenolic or aminic type, provided that there is a free para position in the amine or phenol. They may also be obtained by the molecular rearrangement of the diazoamines, when these are warmed with the parent base and its hydrochloride. This latter method of formation has been studied by H. Goldschmidt and R. U. Reinders (Ber., 1896, 29, p. 1369), who found that the reaction is monomolecular, and that the velocity constant of the reaction is proportional to the amount of the hydrochloride of the base present and also to the temperature, but is independent of the concentration of the diazoamine. The azo compounds are intensely coloured, but are not capable of being used as dyestuffs unless they contain salt-forming, acid or basic groups (see DYEING). By oxidizing agents they are converted into azoxy compounds, and by reducing agents into hydrazo compounds or amines.

Azo-benzene, C6H5N:NC6H5, discovered by E. Mitscherlich in 1834, may be prepared by reducing nitrobenzene in alcoholic solution with zinc dust and caustic soda; by the condensation of nitrosobenzene with aniline in hot glacial acetic acid solution; or by the oxidation of aniline with sodium hypobromite. It crystallizes from alcohol in orange red plates which melt at 68deg C. and boil at 293deg C. It does not react with acids or alkalis, but on reduction with zinc dust in acetic acid solution yields aniline.

_Amino-azo Compounds_ may be prepared as shown above. They are usually yellowish brown or red in colour, the presence of more amino groups leading to browner shades, whilst the introduction of alkylated amino groups gives redder shades. They usually crystallize well and are readily reduced. When heated with aniline and aniline hydrochloride they yield indulines (_q.v._). Amino-azo-benzene, C_6H_5.N_2.C_6H_4NH_2, crystallizes in yellow plates or needles and melts at 126deg C. Its constitution is determined by the facts that it may be prepared by reducing nitro-azo-benzene by ammonium sulphide and that by reduction with stannous chloride it yields aniline and meta-phenylene diamine. Diamino-azo-benzene (chrysoidine), C_6H_5.N_2.C_6H_3(NH_2)_2, first prepared by O. Witt (_Ber._, 1877, 10, p. 656), is obtained by coupling phenyl diazonium chloride with meta-phenylene diamine. It crystallizes in red octahedra and dyes silk and wool yellow. Triamino-azo-benzene (meta-aminobenzene-azo-meta-phenylene diamine or Bismarck brown, phenylene brown, vesuvine, Manchester brown), NH_2.C_6H_4.N_2.C_6H_3(NH_2)_2, is prepared by the action of nitrous acid on meta-phenylene diamine. It forms brown crystals which are readily soluble in hot water, and it dyes mordanted cotton a dark brown. On the composition of the commercial Bismarck brown see E. Tauber and F. Walder (_Ber_., 1897, 30, pp. 2111, 2899; 1900, 33, p. 2116). Alkylated amino-azo-benzenes are also known, and are formed by the coupling of diazonium salts with alkylated amines, provided they contain a free para position with respect to the amino group. In these cases it has been shown by H. Goldschmidt and A. Merz (_Ber_., 1897, 30, p. 670) that the velocity of formation of the amino-azo compound depends only on the nature of the reagents and not on the concentration, and that in coupling the hydrochloride of a tertiary amine with diazobenzene sulphonic acid the reaction takes place between the acid and the base set free by the hydrolytic dissociation of its salt, for the formation of the amino-azo compound, when carried out in the presence of different acids, takes place most rapidly with the weakest acid (H. Goldschmidt and F. Buss, _Ber_., 1897, 30, p. 2075).

Methyl orange (helianthin, gold orange, Mandarin orange), (CH3)2N.C6H4.N2.C6H4SO3Na, is the sodium salt of para-dimethylaminobenzene-azo-benzene sulphonic acid. It is an orange crystalline powder which is soluble in water, forming a yellow solution. The free acid is intensely red in colour. Methyl orange is used largely as an indicator. The constitution of methyl orange follows from the fact that on reduction by stannous chloride in hydrochloric acid solution it yields sulphanilic acid and para-aminodimethyl aniline.

Oxyazo Compounds.—The oxyazo compounds are prepared by adding a solution of a diazonium salt to a cold slightly alkaline solution of a phenol. The diazo group takes up the para position [v.03 p.0082] with regard to the hydroxyl group, and if this be prevented it then goes into the ortho position. It never goes directly into the meta position.

The constitution of the oxyazo compounds has attracted much attention, some chemists holding that they are true azophenols of the type R.N_2.R_1.OH, while others look upon them as having a quinonoid structure, _i.e._ as being quinone hydrazones, type R.NH.N:R_1:O. The first to attack the purely chemical side were Th. Zincke (_Ber._, 1883,16, p. 2929; 1884, 17, p. 3026; 1887, 20, p. 3171) and R. Meldola (_Jour. Chem. Soc._, 1889, 55, pp. 114, 603). Th. Zincke found that the products obtained by coupling a diazonium salt with [alpha]-naphthol, and by condensing phenyl-hydrazine with [alpha]-naphthoquinone, were identical; whilst Meldola acetylated the azophenols, and split the acetyl products by reduction in acid solution, but obtained no satisfactory results. K. Auwers (_Zeit. f. phys. Chem._, 1896, 21, p. 355; _Ber._, 1900, 33, p. 1302) examined the question from the physico-chemical standpoint by determining the freezing-point depressions, the result being that the para-oxyazo compounds give abnormal depressions and the ortho-oxyazo compounds give normal depressions; Auwers then concluded that the para compounds are phenolic and the ortho compounds are quinone hydrazones or act as such. A. Hantzsch (_Ber._, 1899, 32, pp. 590, 3089) considers that the oxyazo compounds are to be classed as pseudo-acids, possessing in the free condition the configuration of quinone hydrazones, their salts, however, being of the normal phenolic type. J. T. Hewitt (_Jour. Chem. Soc._, 1900, 77, pp. 99 et seq.) nitrated para-oxyazobenzene with dilute nitric acid and found that it gave a benzene azo-ortho-nitrophenol, whereas quinones are not attacked by dilute nitric acid. Hewitt has also attacked the problem by brominating the oxyazobenzenes, and has shown that when the hydrobromic acid produced in the reaction is allowed to remain in the system, a brombenzene-azo-phenol is formed, whilst if it be removed (by the addition of sodium acetate) bromination takes place in the phenolic nucleus; consequently the presence of the mineral acid gives the azo compound a pseudo-quinonoid character, which it does not possess if the mineral acid be removed from the sphere of the reaction.

Para-oxyazobenzene (benzene-azo-phenol), C6H5N:N(1).C6H4.OH(4), is prepared by coupling diazotized aniline with phenol in alkaline solution. It is an orange-red crystalline compound which melts at 154deg C. Ortho-oxyazobenzene, C6H5N:N(1)C6H4.OH(2), was obtained in small quantity by E. Bamberger (Ber., 1900, 33, p. 3189) simultaneously with the para compound, from which it may be separated by distillation in a current of steam, the ortho compound passing over with the steam. It crystallizes in orange-red needles which melt at 82.5-83deg C. On reduction with zinc dust in dilute sal-ammoniac solution, it yields ortho-aminophenol and aniline. Meta-oxyazobenzene, C6H5N:N(1)C6H4.OH(3), was obtained in 1903 by P. Jacobson (Ber., 1903, 36, p. 4093) by condensing ortho-anisidine with diazo benzene, the resulting compound being then diazotized and reduced by alcohol to benzene-azo-meta-anisole, from which meta-oxyazobenzene was obtained by hydrolysis with aluminium chloride. It melts at 112-114deg C. and is easily reduced to the corresponding hydrazo compound.

_Diazo-Amines._—The diazo-amines, R.N:N.NHR_1, are obtained by the action of primary amines on diazonium salts; by the action of nitrous acid on a free primary amine, an iso-diazohydroxide being formed as an intermediate product which then condenses with the amine; and by the action of nitrosamines on primary amines. They are crystalline solids, usually of a yellow colour, which do not unite with acids; they are readily converted into amino-azo compounds (see above) and are decomposed by the concentrated halogen acids, yielding haloid benzenes, nitrogen and an amine. Acid anhydrides replace the imino-hydrogen atom by acidyl radicals, and boiling with water converts them into phenols. They combine with phenyl isocyanate to form urea derivatives (H. Goldschmidt, _Ber._, 1888, 21, p. 2578), and on reduction with zinc dust (preferably in alcoholic acetic acid solution) they yield usually a hydrazine and an amine. Diazoamino benzene, C_6H_5.N:N.NHC_6H_5, was first obtained by P. Griess (_Ann._, 1862, 121, p. 258). It crystallizes in yellow laminae, which melt at 96deg C. and explode at slightly higher temperatures. It is readily soluble in alcohol, ether and benzene.

_Diazoimino benzene_, C_6H_5N_3, is also known. It may be prepared by the action of ammonia on diazobenzene perbromide; by the action of hydroxylamine on a diazonium sulphate (K. Heumann and L. Oeconomides, _Ber._, 1887, 20, p. 372); and by the action of phenylhydrazine on a diazonium sulphate. It is a yellow oil which boils at 59deg C. (12 mm.), and possesses a stupefying odour. It explodes when heated. Hydrochloric acid converts it into chloraniline, nitrogen being eliminated; whilst boiling sulphuric acid converts it into aminophenol.

_Azoxy Compounds_, R.[=N.O.N].R', are usually yellow or red crystalline solids which result from the reduction of nitro or nitroso compounds by heating them with alcoholic potash (preferably using methyl alcohol). They may also be obtained by the oxidation of azo compounds. When reduced (in acid solution) they yield amines; distillation with reduced iron gives azo compounds, and warming with ammonium sulphide gives hydrazo compounds. Concentrated sulphuric acid converts azoxybenzene into oxyazobenzene (O. Wallach, _Ber._, 1880, 13, p. 525). Azoxybenzene, (C_6H_5N)_2O, crystallizes from alcohol in yellow needles, which melt at 36deg C. On distillation, it yields aniline and azobenzene. Azoxybenzene is also found among the electro-reduction products of nitrobenzene, when the reduction is carried out in alcoholic-alkaline solution.

The mixed azo compounds are those in which the azo group .N:N. is united with an aromatic radical on the one hand, and with a radical of the aliphatic series on the other. The most easily obtained mixed azo compounds are those formed by the union of a diazonium salt with the potassium or sodium salt of a nitroparaffin (V. Meyer, Ber., 1876, 9, p. 384):

C6H5N2.NO3 + CH3.CH(NO2)K = KNO3 + C6H5N2.CH(NO2)CH3. Benzene-azo-nitro-ethane.

Those not containing a nitro group may be prepared by the oxidation of the corresponding mixed hydrazo compounds with mercuric oxide. E. Bamberger (Ber., 1898, 31, p. 455) has shown that the nitro-alkyl derivatives behave as though they possess the constitution of hydrazones, for on heating with dilute alkalies they split more or less readily into an alkaline nitrite and an acid hydrazide:

C6H5NH.N:C(NO2)CH3 + NaOH = NaNO2 + C6H5NH.NH.CO.CH3.

Benzene-azo-methane, C6H5.N2.CH3, is a yellow oil which boils at 150deg C. and is readily volatile in steam. Benzene-azo-ethane, C6H5.N2.C2H5, is a yellow oil which boils at about 180deg C. with more or less decomposition. On standing with 60% sulphuric acid for some time, it is converted into the isomeric acetaldehyde-phenylhydrazone, C6H5NH.N:CH.CH3 (Ber., 1896, 29, p. 794).

The diazo cyanides, C6H5N2.CN, and carboxylic acids, C6H5.N2.COOH, may also be considered as mixed azo derivatives. Diazobenzenecyanide, C6H5N2.CN, is an unstable oil, formed when potassium cyanide is added to a solution of a diazonium salt. Phenyl-azo-carboxylic acid, C6H5.N2.COOH, is obtained in the form of its potassium salt when phenylsemicarbazide is oxidized with potassium permanganate in alkaline solution (J. Thiele, Ber., 1895, 28, p. 2600). It crystallizes in orange-red needles and is decomposed by water. The corresponding amide, phenyl-azo-carbonamide, C6H5N2.CONH2, also results from the oxidation of phenylsemicarbazide (Thiele, loc. cit.), and forms reddish-yellow needles which melt at 114deg C. When heated with benzaldehyde to 120deg C. it yields diphenyloxytriazole, (C6H5)2CN3C(OH).

AZOIMIDE, or HYDRAZOIC ACID, N3H, a compound of nitrogen and hydrogen, first isolated in 1890 by Th. Curtius (Berichte, 1890, 23, p. 3023). It is the hydrogen compound corresponding to P. Greiss' diazoimino benzene, C6H5N3, which is prepared by the addition of ammonia to diazobenzene perbromide.

Curtius found that benzoyl glycollic acid gave benzoyl hydrazine with hydrazine hydrate:

C6H5OCO.CH2COOH + 2N2H4.H2O = H2O + C6H5CONH.NH2 + NH2.NH.CH2.COOH.

[v.03 p.0083] (Ethyl benzoate may be employed instead of benzoyl glycollic acid for this reaction.) This compound gave a nitroso compound with nitrous acid, which changed spontaneously into benzoylazoimide by loss of water:

C6H5CO.NH.NH2 + HONO = H2O + C6H5CO.N(NO).NH2. C6H5CO.N(NO).NH2 = H2O + C6H5CO.N3.

The resulting benzoylazoimide is easily hydrolysed by boiling with alcoholic solutions of caustic alkalis, a benzoate of the alkali metal and an alkali salt of the new acid being obtained; the latter is precipitated in crystalline condition on standing.

An improved method of preparation was found in the use of hippuric acid, which reacts with hydrazine hydrate to form hippuryl hydrazine, C6H5CONH.CH2CONH.NH2, and this substance is converted by nitrous acid into diazo-hippuramide, C6H5CONH.CH2.CO.NH.N2.OH, which is hydrolysed by the action of caustic alkalis with the production of salts of hydrazoic acid. To obtain the free acid it is best to dissolve the diazo-hippuramide in dilute soda, warm the solution to ensure the formation of the sodium salt, and distil the resulting liquid with dilute sulphuric acid. The pure acid may be obtained by fractional distillation as a colourless liquid of very unpleasant smell, boiling at 30deg C., and extremely explosive. It is soluble in water, and the solution dissolves many metals (zinc, iron, &c.) with liberation of hydrogen and formation of salts (azoimides, azides or hydrazoates). All the salts are explosive and readily interact with the alkyl iodides. In its properties it shows some analogy to the halogen acids, since it forms difficultly soluble lead, silver and mercurous salts. The metallic salts all crystallize in the anhydrous condition and decompose on heating, leaving a residue of the pure metal. The acid is a "weak" acid, being ionized only to a very slight extent in dilute aqueous solution.

E. Noelting and E. Grandmougin (_Berichte_, 1891, 24, p. 2546) obtained azoimide from dinitraniline, C_6H_3(NO_2)_2.NH_2, by diazotization and conversion of the diazo compound into the perbromide, (NO_2)_2C_6H_3.N_2.Br_3. This compound is then decomposed by ammonia, dinitrophenylhydrazoate being formed, which on hydrolysis with alcoholic potash gives potassium hydrazoate (azide) and dinitrophenol. The solution is then acidified and distilled, when azoimide passes over. Somewhat later, they found that it could be prepared from diazobenzene imide, provided a nitro group were present in the ortho or para position to the diazo group. The para-nitro compound is dropped slowly into a cold solution of one part of caustic potash in ten parts of absolute alcohol; the solution becomes dark red in colour and is then warmed for two days on the water bath. After the greater portion of the alcohol has distilled off, the solution is acidified with sulphuric acid and the azoimide distilled over. The yield obtained is only about 40% of that required by theory, on account of secondary reactions taking place. Ortho-nitro-diazobenzene imide only yields 30%.

W. Wislicenus (Berichte, 1892, 25, p. 2084) has prepared the sodium salt by passing nitrous oxide over sodamide at high temperatures. The acid can also be obtained by the action of nitrous acid on hydrazine sulphate; by the oxidation of hydrazine by hydrogen peroxide and sulphuric acid (A. W. Browne, J. Amer. Chem. Soc., 1905, 25, p. 251), or by ammonium metavanadate (A. W. Browne and F. F. Shetterly, Abst. J.C.S., 1907, ii. p. 863).

Ammonium azoimide, N3.NH4, may be prepared by boiling diazohippuramide with alcoholic ammonia, until no more ammonia escapes, the following reaction taking place:

C6H5CO.NHCH2CONH.N2.OH + 2NH3 = N3.NH4 + H2O + C6H5CO.NH.CH2.CO.NH2.

The liquid is then allowed to stand for twelve hours, and the clear alcoholic solution is decanted from the precipitated hippuramide. To the alcoholic solution, four times its volume of ether is added, when the ammonium salt is precipitated. It is then filtered, washed with ether, and air-dried. The salt is readily soluble in water, and is only feebly alkaline. It is extremely explosive. Hydrazine azoimide, N5H5, is also known.

_Chloroazoimide_, Cl.N_3, the chloride corresponding to azoimide, was obtained by F. Raschig (_Ber._, 1908, 41, p. 4194) as a highly explosive colourless gas on acidifying a mixture of sodium azide and hypochlorite with acetic or boric acid.

AZORES (Acores), or WESTERN ISLANDS, an archipelago in the Atlantic Ocean, belonging to the kingdom of Portugal. Pop. (1900) 256,291; area, 922 sq. m. The Azores extend in an oblique line from N.W. to S.E., between 36deg 55' and 39deg 55' N., and between 25deg and 31deg 16' W. They are divided into three widely severed groups, rising from a depth of more than 2-1/2 m. The south-eastern group consists of St Michael's (Sao Miguel) and St Mary (Santa Maria), with Formigas; the central, of Fayal (Faial), Pico, St George (Sao Jorge), Terceira and Graciosa; the north-western, of Flores and Corvo.



The nearest continental land is Cape da Roca on the Portuguese coast, which lies 830 m. E. of St Michael's; while Cape Cantin, the nearest point on the African mainland, is more than 900 m. distant, and Cape Race in Newfoundland, the nearest American headland, is more than 1000 m. Thus the Azores are the farthest from any continent of all the island groups in the Atlantic; but they are usually regarded as belonging to Europe, as their climate and flora are European in character.

Physical Description.—The aspect of all the islands is very similar in general characteristics, presenting an elevated and [v.03 p.0084] undulating outline, with little or no tableland, and rising into peaks, of which the lowest, that of Corvo, is 350 ft., and the highest that of Pico, 7612 ft. above sea-level. The lines of sea-coast are, with few exceptions, high and precipitous, with bases of accumulated masses of fallen rock, in which open bays, or scarcely more enclosed inlets, form the harbours of the trading towns. The volcanic character of the whole archipelago is obvious, and has been abundantly confirmed by the numerous earthquakes and eruptions which have taken place since its discovery. Basalt and scoria are the chief erupted materials. Hitherto Flores, Corvo and Graciosa have been quite exempt, and Fayal has only suffered from one eruption (1672). The centre of activity has for the most part been St Michael's, while the neighbouring island of St Mary has altogether escaped. In 1444-1445 there was a great eruption at St Michael's, of which, however, the accounts that have been preserved exaggerate the importance. In 1522 the town of Villa Franca, at that time the capital of the island, was buried, with all its 6000 inhabitants, during a violent convulsion. In 1572 an eruption took place in Pico; in 1580 St George was the scene of numerous outbursts; and in 1614 a little town in Terceira was destroyed. In 1630, 1652, 1656, 1755, 1852, &c., St Michael's was visited with successive eruptions and earthquakes, several of them of great violence. On various occasions, as in 1638, 1720, 1811 and 1867, subterranean eruptions have taken place, which have sometimes been accompanied by the appearance of temporary islands. Of these the most remarkable was thrown up in June 1811, about half a league from the western extremity of St Michael's. It was called Sabrina by the commander of the British man-of-war of that name, who witnessed the phenomenon.

Climate.—The climate is particularly temperate, but the extremes of sensible heat and cold are increased by the humidity. The range of the thermometer is from 45deg Fahr., the lowest known extreme, or 48deg, the ordinary lowest extreme of January, to 82deg, the ordinary, or 86deg, the highest known extreme of July, near the level of the sea. Between these two points (both taken in the shade) there is from month to month a pretty regular gradation of increase or decrease, amounting to somewhat less than four degrees. In winter the prevailing winds are from the north-west, west and south; in summer the most frequent are the north, north-east and east. The weather is often extremely stormy, and the winds from the west and south-west render the navigation of the coasts very dangerous.

Fauna.—The mammalia of the Azores are limited to the rabbit, weasel, ferret, rat (brown and black), mouse and bat, in addition to domestic animals. The game includes the woodcock, red partridge (introduced in the 16th century), quail and snipe. Owing to the damage inflicted on the crops by the multitude of blackbirds, bullfinches, chaffinches and green canaries, a reward was formerly paid for the destruction of birds in St Michael's, and it is said that over 400,000 were destroyed in several successive years between 1875 and 1885. There are valuable fisheries of tunny, mullet and bonito. The porpoise, dolphin and whale are also common. Whale-fishing is a profitable industry, with its headquarters at Fayal, whence the sperm-oil is exported. Eels are found in the rivers. The only indigenous reptile is the lizard. Fresh-water molluscs are unknown, and near the coast the marine fauna is not rich; but terrestrial molluscs abound, several species being peculiar to the Azores.

Flora.—The general character of the flora is decidedly European, no fewer than 400 out of the 478 species generally considered as indigenous belonging likewise to that continent, while only four are found in America, and forty are peculiar to the archipelago. Vegetation in most of the islands is remarkably rich, especially in grasses, mosses, and ferns, heath, juniper, and a variety of shrubs. Of tall-growing trees there was, till the 19th century, an almost total lack; but the Bordeaux pine, European poplar, African palm-tree, Australian eucalyptus, chestnut, tulip-tree, elm, oak, and many others, were then successfully introduced. The orange, apricot, banana, lemon, citron, Japanese medlar, and pomegranate are the common fruits, and various other varieties are more or less cultivated. At one time much attention was given to the growing of sugar-cane, but it has now for the most part been abandoned. The culture of indigo, introduced in the 16th century, also belongs to the past. A kind of fern (Dicksonia culcita), called by the natives cabellinho, furnishes a silky material for the stuffing of mattresses and is exported to Brazil and Portugal.

Population.—The inhabitants of the islands are mostly of Portuguese origin, with a well-marked strain of Moorish and Flemish blood. There is a high birth-rate and a low average of infant mortality. A large proportion of the poorer classes, especially among the older men and women, are totally illiterate, but education tends to spread more rapidly than in Portugal itself, owing to the custom of sending children to the United States, where they are taught in the state schools. Negroes, mulattoes, English, Scottish and Irish immigrants are present in considerable numbers, especially in Fayal and St Michael's. The total number of resident foreigners in 1900 was 1490.

Government.—The Azores are subdivided into three administrative districts named after their chief towns, i.e. Ponta Delgada, the capital of St Michael's; Angra, or Angra do Heroismo, the capital of Terceira; and Horta, the capital of Fayal. St Michael's and St Mary are included in the district of Ponta Delgada; Terceira, St George and Graciosa, in that of Angra; Pico, Fayal, Flores and Corvo, in that of Horta. Four members are returned by Ponta Delgada to the parliament in Lisbon, while each of the other districts returns two members. Roman Catholicism is the creed of the majority, and Angra is an episcopal see. For purposes of military administration the islands form two commands, with their respective headquarters at Angra and Ponta Delgada. Besides the frequent and regular services of mails which connect the Azores with Portugal and other countries, there is a cable from Lisbon to Villa Franca do Campo, in St Michael's, and thence to Pico, Fayal, St George and Graciosa. Fayal is connected with Waterville, in Ireland, by a cable laid in 1901. At Angra and Ponta Delgada there are meteorological stations. The principal seaports are Angra (pop. 1900, 10,788), Ponta Delgada (17,620), and Horta (6574).

Trade.—The trade of the Azores, long a Portuguese monopoly, is now to a great extent shared by the United Kingdom and Germany, and is chiefly carried in British vessels. Textiles are imported from Portugal; coal from Great Britain; sugar from Germany, Madeira and the United States; stationery, hardware, chemicals, paints, oils, &c., from the United Kingdom and Germany. The exports consist chiefly of fruit, wine, natural mineral waters and provisions. The trade in pineapples is especially important. No fewer than 940,000 pineapples were exported in 1902 and 1903, going in almost equal quantities to London and Hamburg. The fruit is raised under glass. Pottery, cotton fabrics, spirits, straw hats and tea are produced in the district of Ponta Delgada; linen and woollen goods, cheese, butter, soap, bricks and tiles, in that of Angra; baskets, mats, and various ornamental articles made from straw, osier, and the pith of dried fig-wood, in that of Horta.

The largest and most populous of the Azores is St Michael's, which has an area of 297 sq. m., and in 1900 had 121,340 inhabitants. Graciosa (pop. 8385; area, 17 sq. m.) and St George (16,177; 40 sq. m.) form part of the central group. Graciosa is noteworthy for the beauty of its scenery. Its chief towns are Santa Cruz de Graciosa (2185) and Guadalupe (2717). The chief towns of St George are Ribeira Seca (2817) and Velas (2009).

History.—It does not appear that the ancient Greeks and Romans had any knowledge of the Azores, but from the number of Carthaginian coins discovered in Corvo it has been supposed that the islands must have been visited by that adventurous people. The Arabian geographers, Edrisi in the 12th century, and Ibn-al-Wardi in the 14th, describe, after the Canaries, nine other islands in the Western Ocean, which are in all probability the Azores. This identification is supported by various considerations. The number of islands is the same; the climate under which they are placed by the Arabians makes them north of the Canaries; and special mention is made of the hawks or buzzards, which were sufficiently numerous at a later period to [v.03 p.0085] give rise to the present name (Port. Acor, a hawk). The Arabian writers represent them as having been populous, and as having contained cities of some magnitude; but they state that the inhabitants had been greatly reduced by intestine warfare. The Azores are first found distinctly marked in a map of 1351, the southern group being named the Goat Islands (Cabreras); the middle group, the Wind or Dove Islands (De Ventura sive de Columbis); and the western, the Brazil Island (De Brazi)—the word Brazil at that time being employed for any red dye-stuff. In a Catalan map of the year 1375 Corvo is found as Corvi Marini, and Flores as Li Conigi; while St George is already designated San Zorze. It has been conjectured that the discoverers were Genoese, but of this there is not sufficient evidence. It is plain, however, that the so-called Flemish discovery by van der Berg is only worthy of the name in a very secondary sense. According to the usual account, he was driven on the islands in 1432, and the news excited considerable interest at the court of Lisbon. The navigator, Gonzalo Velho Cabral—not to be confounded with his greater namesake, Pedro Alvarez Cabral—was sent to prosecute the discovery. Another version relates that Prince Henry the Navigator of Portugal had in his possession a map in which the islands were laid down, and that he sent out Cabral through confidence in its accuracy. The map had been presented to him by his brother, Dom Pedro, who had travelled as far as Babylon. Be this as it may, Cabral reached the island, which he named Santa Maria, in 1432, and in 1444 took possession of St Michael's. The other islands were all discovered by 1457. Colonization had meanwhile been going on prosperously; and in 1466 Fayal was presented by Alphonso V. to his aunt, Isabella, the duchess of Burgundy. An influx of Flemish settlers followed, and the islands became known for a time as the Flemish Islands. From 1580 to 1640 they were subject, like the rest of the Portuguese kingdom, to Spain. At that time the Azores were the grand rendezvous for the fleets on their voyage home from the Indies; and hence they became a theatre of that maritime warfare which was carried on by the English under Queen Elizabeth against the Peninsular powers. One such expedition, which took place in 1591, led to the famous sea-fight off Flores, between the English ship "Revenge," commanded by Sir Richard Grenville, and a Spanish fleet of fifty-three vessels. Under the active administration of the marquis de Pombal (1690-1782), considerable efforts were made for the improvement of the Azores, but the stupid and bigoted government which followed rather tended to destroy these benefits. Towards the beginning of the 19th century, the possession of the islands, was contested by the claimants for the crown of Portugal. The adherents of the constitution, who supported against Miguel the rights of Maria (II.) da Gloria, obtained possession of Terceira in 1829, where they succeeded in maintaining themselves, and after various struggles, Queen Maria's authority was established over all the islands. She resided at Angra from 1830 to 1833.

For a general account of the islands, see The Azores, by W. F. Walker (London, 1886), and Madeira and the Canary Islands, with the Azores, by A. S. Brown (London, 1901). On the fauna and flora of the islands, the following books by H. Drouet are useful:—Elements de la faune acoreenne (Paris, 1861); Mollusques marins des iles Acores (1858), Lettres acoreennes (1862), and Catalogue de la flore des iles Acores, precede de l'itineraire d'une voyage dans cet archipel (1866). The progress of Azorian commerce is best shown in the British and American consular reports. For history, see La Conquista de las Azores en 1583, by C. Fernandez Duro (Madrid, 1886), and Histoire de la decouverte des iles Azores et de l'origine de leur denomination d'iles flamandes, by J. Mees (Ghent, 1901).

AZOTH, the name given by the alchemists to mercury, and by Paracelsus to his universal remedy.

AZOTUS, the name given by Greek and Roman writers to Ashdod, an ancient city of Palestine, now represented by a few remains in the little village of 'Esdud, in the governmental district of Acre. It was situated about 3 m. inland from the Mediterranean, on the famous military route between Syria and Egypt, about equidistant (18 m.) from Joppa and Gaza. As one of the five chief cities of the Philistines and the seat of the worship of Dagon (1 Sam. v.; cf. 1 Macc. x. 83), it maintained, down even to the days of the Maccabees, a vigorous though somewhat intermittent independence against the power of the Israelites, by whom it was nominally assigned to the territory of Judah. In 711 B.C. it was captured by the Assyrians (Is. xx. 1), but soon regained its power, and was strong enough in the next century to resist the assaults of Psammetichus, king of Egypt, for twenty-nine years (Herod. ii. 157). Restored by the Roman Gabinius from the ruins to which it had been reduced by the Jewish wars (1 Macc. v. 68, x. 77, xvi. 10), it was presented by Augustus to Salome, the sister of Herod. The only New Testament reference is in Acts viii. 40. Ashdod became the seat of a bishop early in the Christian era, but seems never to have attained any importance as a town. The Mount Azotus of 1 Macc. ix. 15, where Judas Maccabeus fell, is possibly the rising ground on which the village stands. A fine Saracenic khān is the principal relic of antiquity at 'Esdud.

AZOV, or Asov (in Turkish, Asak), a town of Russia, in the government of the Don Cossacks, on the left bank of the southern arm of the Don, about 20 m. from its mouth. The ancient Tanais lay some 10 m. to the north. In the 13th century the Genoese had a factory here which they called Tana. Azov was long a place of great military and commercial importance. Peter the Great obtained possession of it after a protracted siege in 1696, but in 1711 restored it to the Turks; in 1739 it was finally united to the Russian empire. Since then it has greatly declined, owing to the silting up of its harbour and the competition of Taganrog. Its population, principally engaged in the fisheries, numbered 25,124 in 1900.

AZOV, SEA OF an inland sea of southern Europe, communicating with the Black Sea by the Strait of Yenikale, or Kerch, the ancient Bosporus Cimmerius. To the Romans it was known as the Palus Maeotis, from the name of the neighbouring people, who called it in their native language Temarenda, or Mother of Waters. It was long supposed to possess direct communication with the Northern Ocean. In prehistoric times a connexion with the Caspian Sea existed; but since the earliest historical times no great change has taken place in regard to the character or relations of the Sea of Azov. It lies between 45deg 20' and 47deg 18' N. lat, and between 35deg and 39deg E. long., its length from south-west to north-east being 230 m., and its greatest breadth 110. The area runs to 14,515 sq. m. It generally freezes from November to the middle of April. The Don is its largest and, indeed, its only very important affluent. Near the mouth of that river the depth of the sea varies from 3 to 10 ft., and the greatest depth does not exceed 45 ft. Of recent years, too, the level has been constantly dropping, for the surface lies 4-3/4 ft. higher than the surface of the Black Sea. Fierce and continuous winds from the east prevail during July and August, and in the latter part of the year those from the north-east and south-east are not unusual; a great variety of currents is thus produced. The water is for the most part comparatively fresh, but differs considerably in this respect according to locality and current. Fish are so abundant that the Turks describe it as Baluk-deniz, or Fish Sea. To the west, separated from the main basin by the long narrow sand-spit of Arabat, lie the remarkable lagoons and marshes known as the Sivash, or Putrid Sea; here the water is intensely salt. The Sea of Azov is of great importance to Russian commerce; along its shores stand the cities of Taganrog, Berdyansk, Mariupol and Yenikale.

AZOXIMES (furo [a.b.] diazoles), a class of organic compounds which contain the ring system

HC = N N = CH[ ]/[ ]O.

They may be prepared by converting nitriles into amidoximes by the action of hydroxylamine, the amidoximes so formed being then acylated by acid chlorides or anhydrides. From these acyl derivatives the elements of water are removed, either by simple heating or by boiling their aqueous solution; this elimination is accompanied by the formation of the azoxime ring. Thus

NH2OH // N.OH boil with C6H5CN ————> C6H5.C ————> NH2 propionic anhydride

[ //N.O.COC_2H_5 ] // N.O [ C_6H_5C ] —> C_6H_5.C C.C_2H_5. [ NH_2 ] N //

[v.03 p.0086] Azoximes can also be produced from [alpha]-benzil dioxime by the "Beckmann" change. Most of the azoximes are very volatile substances, sublime readily, and are easily soluble in water, alcohol and benzene.

For detailed descriptions, see F. Tiemann (Ber., 1885, 18, p. 1059), O. Schulz (Ber., 1885, 18, pp. 1084, 2459), and G. Mueller (Ber., 1886, 19, p. 1492); also Annual Reports of the Chemical Society).

AZTECS (from the Nahuatl word aztlan, "place of the Heron," or "Heron" people), the native name of one of the tribes that occupied the tableland of Mexico on the arrival of the Spaniards in America. It has been very frequently employed as equivalent to the collective national title of Nahuatlecas or Mexicans. The Aztecs came, according to native tradition, from a country to which they gave the name of Aztlan, usually supposed to lie towards the north-west, but the satisfactory localization of it is one of the greatest difficulties in Mexican history. The date of the exodus from Aztlan is equally undetermined, being fixed by various authorities in the 11th and by others in the 12th century. One Mexican manuscript gives a date equivalent to A.D. 1164. They gradually increased their influence among other tribes, until, by union with the Toltecs, who occupied the tableland before them, they extended their empire to an area of from 18,000 to 20,000 square leagues. The researches of Humboldt gave the first clear insight into the early periods of their history. See MEXICO; NAHUATLAN STOCK.

AZUAGA, a town of western Spain, in the province of Badajoz, on the Belmez-Fuente del Arco railway. Pop. (1900) 14,192. Azuaga is the central market for the live-stock of the broad upland pastures watered by the Matachel, a left-hand tributary of the Guadiana, and by the Bembezar, a right-hand tributary of the Guadalquivir. Coarse woollen goods and pottery are manufactured in the town.

AZUAY (sometimes written ASSUAY), a province of Ecuador, bounded N. by the province of Canar, E. by Oriente, S. by Loja, and W. by El Oro. It was formerly called Cuenca, and formed part of the department of Azuay, which also included the province of Loja. Azuay is an elevated mountainous district with a great variety of climates and products; among the latter are silver, quicksilver, wheat, Indian corn, barley, cattle, wool, cinchona and straw hats. The capital is Cuenca.

AZUNI, DOMENICO ALBERTO (1749-1827), Italian jurist, was born at Sassar, in Sardinia, in 1749. He studied law at Sassari and Turin, and in 1782 was made judge of the consulate at Nice. In 1786-1788 he published his Dizionario Universale Ragionato della Giurisprudenza Mercantile. In 1795 appeared his systematic work on the maritime law of Europe, Sistema Universale dei Principii del Diritto Maritimo dell' Europa, which he afterwards recast and translated into French. In 1806 he was appointed one of the French commission engaged in drawing up a general code of commercial law, and in the following year he proceeded to Genoa as president of the court of appeal. After the fall of Napoleon in 1814, Azuni lived for a time in retirement at Genoa, till he was invited to Sardinia by Victor Emmanuel I., and appointed judge of the consulate at Cagliari, and director of the university library. He died at Cagliari in 1827. Azuni also wrote numerous pamphlets and minor works, chiefly on maritime law, an important treatise on the origin and progress of maritime law (Paris, 1810), and an historical, geographical and political account of Sardinia (1799, enlarged 1802).

AZURARA, GOMES EANNES DE (?-1474), the second notable Portuguese chronicler in order of date. He adopted the career of letters in middle life. He probably entered the royal library as assistant to Fernao Lopes (q.v.) during the reign of King Duarte (1433-1438), and he had sole charge of it in 1452. His Chronicle of the Siege and Capture of Ceuta, a supplement to the Chronicle of King John I., by Lopes, dates from 1450, and three years later he completed the first draft of the Chronicle of the Discovery and Conquest of Guinea, our authority for the early Portuguese voyages of discovery down the African coast and in the ocean, more especially for those undertaken under the auspices of Prince Henry the Navigator. It contains some account of the life work of that prince, and has a biographical as well as a geographical interest. On the 6th of June 1454 Azurara became chief keeper of the archives and royal chronicler in succession to Fernao Lopes. In 1456 King Alphonso V. commissioned him to write the history of Ceuta, "the land-gate of the East," under the governorship of D. Pedro de Menezes, from its capture in 1415 until 1437, and he had it ready in 1463. A year afterwards the king charged him with a history of the deeds of D. Duarte de Menezes, captain of Alcacer, and, proceeding to Africa, he spent a twelvemonth in the town collecting materials and studying the scenes of the events he was to describe, and in 1468 he completed the chronicle. Alphonso corresponded with Azurara on terms of affectionate intimacy, and no less than three commendas of the order of Christ rewarded his literary services. He has little of the picturesque ingenuousness of Lopes, and loved to display his erudition by quotations and philosophical reflections, showing that he wrote under the influence of the first Renaissance. Nearly all the leading classical, early Christian and medieval writers figure in his pages, and he was acquainted with the notable chronicles and romances of Europe and had studied the best Italian and Spanish authors. In addition, he had mastered the geographical system of the ancients and their astrology. As an historian he is laborious, accurate and conscientious, though his position did not allow him to tell the whole truth about his hero, Prince Henry.

His works include: (1) Chronica del Rei D. Joam I. Terceira parte em que se contem a tomada de Ceuta (Lisbon, 1644); (2) Chronica do Descobrimento e Conquista de Guine (Paris, 1841; Eng. version in 2 vols. issued by the Hakluyt Society, London, 1896-1899); (3) Chronica do Conde D. Pedro (de Menezes), printed in the Ineditos de Historia Portugueza, vol. ii. (Lisbon, 1792); (4) Chronica do Conde D. Duarte de Menezes, printed in the Ineditos, vol. iii. (Lisbon, 1793). The preface to the English version of the Chronicle of Guinea contains a full account of the life and writings of Azurara and cites all the authorities.

AZURE (derived, through the Romance languages, from the Arabic al-lazward, for the precious stone lapis lazuli, the initial l having dropped), the lapis lazuli; and so its colour, blue.



AZURITE, or CHESSYLITE, a mineral which is a basic copper carbonate, 2CuCO3.Cu(OH)2. In its vivid blue colour it contrasts strikingly with the emerald-green malachite, also a basic copper carbonate, but containing rather more water and less carbon dioxide. It was known to Pliny under the name caeruleum, and the modern name azurite (given by F. S. Beudant in 1824) also has reference to the azure-blue colour; the name chessylite, also in common use, is of later date (1852), and is from the locality, Chessy near Lyons, which has supplied the best crystallized specimens of the mineral. Crystals of azurite belong to the monoclinic system; they have a vitreous lustre and are translucent. The streak is blue, but lighter than the colour of the mineral in mass. Hardness 3-1/2—4; sp. gr. 3.8.

Azurite occurs with malachite in the upper portions of deposits of copper ore, and owes its origin to the alteration of the sulphide or of native copper by water containing carbon dioxide and oxygen. It is thus a common mineral in all copper mines, and sometimes occurs in large masses, as in Arizona and in South Australia, where it has been worked as an ore of copper, of which element it contains 55%. Being less hydrated than malachite it is itself liable to alteration into this mineral, and pseudomorphs of malachite after azurite are not uncommon. Occasionally the massive material is cut and polished for decorative purposes, though the application in this direction is far less extensive than that of malachite.

AZYMITES (Gr. [Greek: a-], without; [Greek: zume], leaven), a name given by the Orthodox Eastern to the Western or Latin Church, because of the latter's use of unleavened bread in the Eucharist, a practice which arose in the 9th century and is also observed by Armenians and Maronites following the Jewish passover custom. The Orthodox Church strenuously maintains its point, arguing that the very name bread, the holiness of the mystery, and the example of Jesus and the early church alike, testify against the use of unleavened bread in this connexion.

[v.03 p.0087]

B This letter corresponds to the second symbol in the Phoenician alphabet, and appears in the same position in all the European alphabets, except those derived, like the Russian, from medieval Greek, in which the pronunciation of this symbol had changed from b to v. A new form had therefore to be invented for the genuine b in Slavonic, to which there was, at the period when the alphabet was adopted, no corresponding sound in Greek. The new symbol, which occupies the second position, was made by removing the upper loop of B, thus producing a symbol somewhat resembling an ordinary lowercase b. The old B retained the numerical value of the Greek [beta] as 2, and no numerical value was given to the new symbol. In the Phoenician alphabet the earliest forms are [Two Bs] or more rounded [1]. The rounded form appears also in the earliest Aramaic (see ALPHABET). Like some other alphabetic symbols it was not borrowed by Greek in its original form. In the very early rock inscriptions of Thera (700-600 B.C.), written from right to left; it appears in a form resembling the ordinary Greek [lambda]; this form apparently arose from writing the Semitic symbol upside down. Its form in inscriptions of Melos, Selinus, Syracuse and elsewhere in the 6th and 5th centuries suggests the influence of Aramaic forms in which the head of the letter is opened, [2]. The Corinthian [3], [4] and [5] (also at Corcyra) and the [Two Bs] of Byzantine coins are other adaptations of the same symbol. The form [6] which it takes in the alphabets of Naxos, Delos and other Ionic islands at the same period is difficult to explain. Otherwise its only variation is between pointed and rounded loops ([7] and [8]). The sound which the symbol represents is the voiced stop made by closing the lips and vibrating the vocal chords (see PHONETICS). It differs from p by the presence of vibration of the vocal chords and from m because the nasal passage as well as the lips is closed. When an audible emission of breath attends its production the aspirate bh is formed. This sound was frequent in the pro-ethnic period of the Indo-European languages and survived into the Indo-Aryan languages. According to the system of phonetic changes generally known as "Grimm's law," an original b appears in English as p, an original bh as b. An original medial p preceding the chief accent of the word also appears as b in English and the other members of the same group. It is not certain that any English word is descended from an original word beginning with b, though it has been suggested that peg is of the same origin as the Latin baculum and the Greek [Greek: baktron]. When the lips are not tightly closed the sound produced is not a stop, but a spirant like the English w. In Late Latin there was a tendency to this spirant pronunciation which appears as early as the beginning of the 2nd century A.D.; by the 3rd century b and consonantal u are inextricably confused. When this consonantal u (English w as seen in words borrowed very early from Latin like wall and wine) passed into the sound of English v (labio-dental) is not certain, but Germanic words borrowed into Latin in the 5th century A.D. have in their Latin representation gu- for Germanic w-, guisa corresponding to English wise and reborrowed indirectly as guise.

The earliest form of the name of the symbol which we can reach is the Hebrew beth, to which the Phoenician must have been closely akin, as is shown by the Greek [Greek: beta], which is borrowed from it with a vowel affixed.

BAADER, FRANZ XAVER VON (1765-1841), German philosopher and theologian, born on the 27th of March 1765 at Munich, was the third son of F. P. Baader, court physician to the elector of Bavaria. His brothers were both distinguished—the elder, Clemens, as an author; the second, Joseph (1763-1835), as an engineer. Franz studied medicine at Ingolstadt and Vienna, and for a short time assisted his father in his practice. This life he soon found uncongenial, and decided on becoming a mining engineer. He studied under Abraham Gottlob Werner at Freiberg, travelled through several of the mining districts in north Germany, and for four years, 1792-1796, resided in England. There he became acquainted with the works of Jakob Boehme, and with the ideas of Hume, Hartley and Godwin, which were extremely distasteful to him. The mystical speculations of Meister Eckhart, Saint Martin, and above all those of Boehme, were more in harmony with his mode of thought. In 1796 he returned from England, and in Hamburg became acquainted with F. H. Jacobi, with whom he was for years on terms of friendship. He now learned something of Schelling, and the works he published during this period were manifestly influenced by that philosopher. Yet Baader is no disciple of Schelling, and probably gave out more than he received. Their friendship continued till about the year 1822, when Baader's denunciation of modern philosophy in his letter to the emperor Alexander I. of Russia entirely alienated Schelling.

All this time Baader continued to apply himself to his profession of engineer. He gained a prize of 12,000 gulden (about L1000) for his new method of employing Glauber's salts instead of potash in the making of glass. From 1817 to 1820 he held the post of superintendent of mines, and was raised to the rank of nobility for his services. He retired in 1820, and soon after published one of the best of his works, Fermenta Cognitionis, 6 parts, 1822-1825, in which he combats modern philosophy and recommends the study of Boehme. In 1826, when the new university was opened at Munich, he was appointed professor of philosophy and speculative theology. Some of the lectures delivered there he published under the title, Spekulative Dogmatik, 4 parts, 1827-1836. In 1838 he opposed the interference in civil matters of the Roman Catholic Church, to which he belonged, and in consequence was, during the last three years of his life, interdicted from lecturing on the philosophy of religion. He died on the 23rd of May 1841.

It is difficult to summarize Baader's philosophy, for he himself generally gave expression to his deepest thoughts in obscure aphorisms, or mystical symbols and analogies (see Ed. Zeller's Ges. d. deut. Phil. 732, 736). Further, he has no systematic works; his doctrines exist for the most part in short detached essays, in comments on the writings of Boehme and Saint Martin, or in his extensive correspondence and journals. At the same time there are salient points which mark the outline of his thought. Baader starts from the position that human reason by itself can never reach the end it aims at, and maintains that we cannot throw aside the presuppositions of faith, church and tradition. His point of view may be described as Scholasticism; for, like the scholastic doctors, he believes that theology and philosophy are not opposed sciences, but that reason has to make clear the truths given by authority and revelation. But in his attempt to draw still closer the realms of faith and knowledge he approaches more nearly to the mysticism of Eckhart, Paracelsus and Boehme. Our existence depends on the fact that we are cognized by God (cogitor ergo cogito et sum). All self-consciousness is at the same time God-consciousness; our knowledge is never mere scientia, it is invariably con-scientia—a knowing with, consciousness of, or participation in God. Baader's philosophy is thus essentially a theosophy. God is not to be conceived as mere abstract Being (substantia), but as everlasting process, activity (actus). Of this process, this self-generation of God, we may distinguish two aspects—the immanent or esoteric, and the emanent or exoteric. God has reality only in so far as He is absolute spirit, and only in so far as the primitive will is conscious of itself can it become spirit at all. But in this very cognition of self is involved the distinction of knower and known, from which proceeds the power to become spirit. This immanent process of self-consciousness, wherein indeed a trinity of persons is not given but only rendered possible, is mirrored in, and takes place through, the eternal and impersonal idea or wisdom of God, which exists beside, though not distinct from, the primitive will. Concrete reality or personality is given to this divine Ternar, as Baader calls it, through nature, the principle of self-hood, of individual being, which is eternally and necessarily produced by God. Only in nature is the trinity of persons attained. These processes, it must be noticed, are not to be conceived as successive, or as taking place in time; they are to be looked at sub specie aeternitatis, as the necessary elements or moments in the self-evolution of the divine Being. Nor is nature to be confounded with created substance, or with matter as it exists in space and time; it is pure non-being, the mere otherness (alteritas) of God-his shadow, desire, want, or desiderium sui, as it is called by mystical writers. Creation, itself a free and non-temporal act of God's love and will, cannot be speculatively deduced, but must be accepted as an historic [v.03 p.0088] fact. Created beings were originally of three orders—the intelligent or angels; the non-intelligent natural existences; and man, who mediated between these two orders. Intelligent beings are endowed with freedom; it is possible, but not necessary, that they should fall. Hence the fact of the fall is not a speculative but an historic truth. The angels fell through pride—through desire to raise themselves to equality with God; man fell by lowering himself to the level of nature. Only after the fall of man begins the creation of space, time and matter, or of the world as we now know it; and the motive of this creation was the desire to afford man an opportunity for taking advantage of the scheme of redemption, for bringing forth in purity the image of God according to which he has been fashioned. The physical philosophy and anthropology which Baader, in connexion with this, unfolds in various works, is but little instructive, and coincides in the main with the utterances of Boehme. In nature and in man he finds traces of the dire effects of sin, which has corrupted both and has destroyed their natural harmony. As regards ethics, Baader rejects the Kantian or any autonomic system of morals. Not obedience to a moral law, but realization in ourselves of the divine life is the true ethical end. But man has lost the power to effect this by himself; he has alienated himself from God, and therefore no ethical theory which neglects the facts of sin and redemption is satisfactory or even possible. The history of man and of humanity is the history of the redeeming love of God. The means whereby we put ourselves so in relation with Christ as to receive from Him his healing virtue are chiefly prayer and the sacraments of the church; mere works are never sufficient. Man in his social relations is under two great institutions. One is temporal, natural and limited—the state; the other is eternal, cosmopolitan and universal—the church. In the state two things are requisite: first, common submission to the ruler, which can be secured or given only when the state is Christian, for God alone is the true ruler of men; and, secondly, inequality of rank, without which there can be no organization. A despotism of mere power and liberalism, which naturally produces socialism, are equally objectionable. The ideal state is a civil community ruled by a universal or Catholic church, the principles of which are equally distinct from mere passive pietism, or faith which will know nothing, and from the Protestant doctrine, which is the very radicalism of reason.

Baader is, without doubt, among the greatest speculative theologians of modern Catholicism, and his influence has extended itself even beyond the precincts of his own church. Among those whom he influenced were R. Rothe, Julius Mueller and Hans L. Markensen.

His works were collected and published by a number of his adherents—F. Hoffman, J. Hamberger, E. v. Schaden, Lutterbeck, von Osten-Sacken and Schlueter—Baader's saemmtliche Werke (16 vols., 1851-1860). Valuable introductions by the editors are prefixed to the several volumes. Vol. xv. contains a full biography; vol. xvi. an index, and an able sketch of the whole system by Lutterbeck. See F.

BAAL, a Semitic word, which primarily signifies lord, owner or inhabitant,[9] and then, in accordance with the Semitic way of looking at family and religious relations, is specially appropriated to express the relation of a husband to his wife and of the deity to his worshipper. In the latter usage it indicated not that the god was the lord of the worshipper, but rather the possessor of, or ruler in, some place or district. In the Old Testament it is regularly written with the article, i.e. "the Baal"; and the baals of different tribes or sanctuaries were not necessarily conceived as identical, so that we find frequent mention of Baalim, or rather "the Baalim" in the plural. That the Israelites even applied the title of Baal to Yahweh himself is proved by the occurrence of such names as Jerubbaal (Gideon), Eshbaal (one of Saul's sons) and Beeliada (a son of David, 1 Chron. xiv. 7). The last name appears in 2 Sam. v. 16 as Eliada, showing that El (God) was regarded as equivalent to Baal; cf. also the name Be'aliah, "Yahweh is baal or lord," which survives in 1 Chron. xii. 5. However, when the name Baal was exclusively appropriated to idolatrous worship (cf. Hos. ii. 16 seq.), abhorrence for the unholy word was marked by writing bōsheth (shameful thing) for baal in compound proper names, and thus we get the usual forms Ishbosheth, Mephibosheth.

The great difficulty which has been felt by investigators in determining the character and attributes of the god Baal mainly arises from the original appellative sense of the word, and many obscure points become clear if we remember that when a title becomes a proper name it may be appropriated by different peoples to quite distinct deities. Baal being originally a title, and not a proper name, the innumerable baals could be distinguished by the addition of the name of a place or of some special attribute.[10] Accordingly, the baals are not to be regarded necessarily as local variations of one and the same god, like the many Virgins or Madonnas of Catholic lands, but as distinct numina. Each community could speak of its own baal, although a collection of allied communities might share the same cult, and naturally, since the attributes ascribed to the individual baals were very similar, subsequent syncretism was facilitated.

The Baal, as the head of each worshipping group, is the source of all the gifts of nature (cf. Hos. ii. 8 seq., Ezek. xvi. 19); as the god of fertility all the produce of the soil is his, and his adherents bring to him their tribute of first-fruits. He is the patron of all growth and fertility, and, by the "uncontrolled use of analogy characteristic of early thought," the Baal is the god of the productive element in its widest sense. Originating probably, in the observation of the fertilizing effect of rains and streams upon the receptive and reproductive soil, baalism becomes identical with the grossest nature-worship. Joined with the baals there are naturally found corresponding female figures known as Ashtārōth, embodiments of Ashtōreth (see ASTARTE; ISHTAR). In accordance with primitive notions of analogy,[11] which assume that it is possible to control or aid the powers of nature by the practice of "sympathetic magic" (see MAGIC), the cult of the baals and Ashtārōth was characterized by gross sensuality and licentiousness.

The fragmentary allusions to the cult of Baal Peor (Num. xxv., Hos. ix. 10, Ps. cvi. 28 seq.) exemplify the typical species of Dionysiac orgies that prevailed.[12] On the summits of hills and mountains flourished the cult of the givers of increase, and "under every green tree" was practised the licentiousness which in primitive thought was held to secure abundance of crops (see Frazer, Golden Bough, 2nd ed. vol. ii. pp. 204 sqq.). Human sacrifice (Jer. xix. 5), the burning of incense (Jer. vii. 9), violent and ecstatic exercises, ceremonial acts of bowing and kissing, the preparing of sacred mystic cakes, appear among the offences denounced by the Israelite prophets, and show that the cult of Baal (and Astarte) included the characteristic features of heathen worship which recur in various parts of the Semitic world, although attached to other names.[13]

By an easy transition the local gods of the streams and springs which fertilized the increase of the fields became identified with [v.03 p.0089] the common source of all streams, and proceeding along this line it was possible for the numerous baals to be regarded eventually as mere forms of one absolute deity. Consequently, the Baal could be identified with some supreme power of nature, e.g. the heavens, the sun, the weather or some planet. The particular line of development would vary in different places, but the change from an association of the Baal with earthly objects to heavenly is characteristic of a higher type of belief and appears to be relatively later. The idea which has long prevailed that Baal was properly a sky-god affords no explanation of the local character of the many baals; on the other hand, on the theory of a higher development where the gods become heavenly or astral beings, the fact that ruder conceptions of nature were still retained (often in the unofficial but more popular forms of cult) is more intelligible.

A specific Baal of the heavens appears to have been known among the Hittites in the time of Rameses II., and considerably later, at the beginning of the 7th century, it was the title of one of the gods of Phoenicia. In Babylonia, from a very early period, Baal became a definite individual deity, and was identified with the planet Jupiter. This development is a mark of superior culture and may have been spread through Babylonian influence. Both Baal and Astarte were venerated in Egypt at Thebes and Memphis in the XIXth Dynasty, and the former, through the influence of the Aramaeans who borrowed the Babylonian spelling Bel, ultimately became known as the Greek Belos who was identified with Zeus.

Of the worship of the Tyrian Baal, who is also called Melkart (king of the city), and is often identified with the Greek Heracles, but sometimes with the Olympian Zeus, we have many accounts in ancient writers, from Herodotus downwards. He had a magnificent temple in insular Tyre, founded by Hiram, to which gifts streamed from all countries, especially at the great feasts. The solar character of this deity appears especially in the annual feast of his awakening shortly after the winter solstice (Joseph. C. Apion. i. 18). At Tyre, as among the Hebrews, Baal had his symbolical pillars, one of gold and one of smaragdus, which, transported by phantasy to the farthest west, are still familiar to us as the Pillars of Hercules. The worship of the Tyrian Baal was carried to all the Phoenician colonies.[14] His name occurs as an element in Carthaginian proper names (Hannibal, Hasdrubal, &c.), and a tablet found at Marseilles still survives to inform us of the charges made by the priests of the temple of Baal for offering sacrifices.

The history of Baalism among the Hebrews is obscured by the difficulty of determining whether the false worship which the prophets stigmatize is the heathen worship of Yahweh under a conception, and often with rites, which treated him as a local nature god; or whether Baalism was consciously recognized to be distinct from Yahwism from the first. Later religious practice was undoubtedly opposed to that of earlier times, and attempts were made to correct narratives containing views which had come to be regarded as contrary to the true worship of Yahweh. The Old Testament depicts the history of the people as a series of acts of apostasy alternating with subsequent penitence and return to Yahweh, and the question whether this gives effect to actual conditions depends upon the precise character of the elements of Yahweh worship brought by the Israelites into Palestine. This is still under dispute. There is strong evidence at all events that many of the conceptions are contrary to historical fact, and the points of similarity between native Canaanite cult and Israelite worship are so striking that only the persistent traditions of Israel's origin and of the work of Moses compel the conclusion that the germs of specific Yahweh worship existed from his day. The earliest certain reaction against Baalism is ascribed to the reign of Ahab, whose marriage with Jezebel gave the impulse to the introduction of a particular form of the cult. In honour of his wife's god, the king, following the example of Solomon, erected a temple to the Tyrian Baal (see above). This, however, did not prevent him from remaining a follower of Yahweh, whose prophets he still consulted, and whose protection he still cherished when he named his sons Ahaziah and Jehoram ("Yah[weh] holds," "Y. is high"). The antagonism of Elijah was not against Baalism in general, but against the introduction of a rival deity. But by the time of Hosea (ii. 16 seq.) a further advance was marked, and the use of the term "Baal" was felt to be dangerous to true religion. Thus there gradually grew up a tendency to avoid the term, and in accordance with the idea of Ex. xxiii. 13, it was replaced by the contemptuous bōsheth, "shame" (see above). However, the books of Deuteronomy and Jeremiah (cf. also Zeph. i. 4) afford complete testimony for the prevalence of Baalism as late as the exile, but prove that the clearest distinction was then drawn between the pure worship of Yahweh the god of Israel and the inveterate and debased cults of the gods of the land.

[1] Cf. its use as a noun of relation e.g. a ba'al of hair, "a hairy man" (2 Kings i. 8), b. of wings, "a winged creature," and in the plural, b. of arrows, "archers" (Gen. xlix. 23), b. of oath, "conspirators" (Neh. vi. 18).

[2] Compounds with geographical terms (towns, mountains), e.g. Baal of Tyre, of Lebanon, &c., are frequent; see G. B. Gray, Heb. Proper Names, pp. 124-126. Baal-berith or El-berith of Shechem (Judg. ix. 4, 46) is usually interpreted to be the Baal or God of the covenant, but whether of covenants in general or of a particular covenant concluded at Shechem is disputed. The [Greek: Balmarkos] (near Beirut) apparently presided over dancing; another compound (in Cyprus) seems to represent a Baal of healing. On the "Baal of flies" see BEELZEBUB.

[3] The general analogy shows itself further in the idea of the deity as the husband (ba'al) of his worshippers or of the land in which they dwell. The Astarte of Gabal (Byblus) was regularly known as the ba'alath (fem. of baal), her real name not being pronounced (perhaps out of reverence).

[5] The extent to which elements of heathen cult entered into purer types of religion is illustrated in the worship of Yahweh. The sacred cakes of Astarte and old holy wells associated with her cult were later even transferred to the worship of the Virgin (Ency. Bib. col. 3993; Rouvier, in Bull. Archeol., 1900, p. 170).

[6] The sanctuary of Heracles at Daphne near Antioch was properly that of the Semitic Baal, and at Amathus Jupiter Hospes takes the place of Heracles or Malika, in which the Tyrian Melkart is to be recognized (W. R. Smith, Rel. Sem. 2nd ed. pp. 178, 376). See further PHOENICIA.

BAALBEK (anc. Heliopolis), a town of the Buka'a (Coelesyria), altitude 3850 ft., situated E. of the Litani and near the parting between its waters and those of the Asi. Pop. about 5000, including 2000 Metawali and 1000 Christians (Maronite and Orthodox). Since 1902 Baalbek has been connected by railway with Rayak (Rejak) on the Beirut-Damascus line, and since 1907 with Aleppo. It is famous for its temple ruins of the Roman period, before which we have no record of it, certain though it be that Heliopolis is a translation of an earlier native name, in which Baal was an element. It has been suggested, but without good reason, that this name was the Baalgad of Josh. xi. 17.

Heliopolis was made a colonia probably by Octavian (coins of 1st century A.D.), and there must have been a Baal temple there in which Trajan consulted the oracle. The foundation of the present buildings, however, dates from Antoninus Pius, and their dedication from Septimius Severus, whose coins first show the two temples. The great courts of approach were not finished before the reigns of Caracalla and Philip. In commemoration, no doubt, of the dedication of the new sanctuaries, Severus conferred the jus Italicum on the city. The greater of the two temples was sacred to Jupiter (Baal), identified with the Sun, with whom were associated Venus and Mercury as [Greek: sumbomoi theoi]. The lesser temple was built in honour of Bacchus (not the Sun, as formerly believed). Jupiter-Baal was represented locally as a beardless god in long scaly drapery, holding a whip in his right hand and lightning and ears of corn in his left. Two bulls supported him. In this guise he passed into European worship in the 3rd and 4th centuries A.D. The extreme licence of the Heliopolitan worship is often animadverted upon by early Christian writers, and Constantine, making an effort to curb the Venus cult, built a basilica. Theodosius erected another, with western apse, in the main court of the Jupiter temple.

When Abu Ubaida (or Obaida) attacked the place after the Moslem capture of Damascus (A.D. 635), it was still an opulent city and yielded a rich booty. It became a bone of contention between the various Syrian dynasties and the caliphs first of Damascus, then of Egypt, and in 748 was sacked with great slaughter. In 1090 it passed to the Seljuks, and in 1134 to Jenghiz Khan; but after 1145 it remained attached to Damascus and was captured by Saladin in 1175. The Crusaders raided its valley more than once, but never took the city. Three times shaken by earthquake in the 12th century, it was dismantled by Hulagu in 1260. But it revived, and most of its fine Moslem mosque and fortress architecture, still extant, belongs to the [v.03 p.0090] reign of Sultan Kalaūn (1282) and the succeeding century, during which Abulfeda describes it as a very strong place. In 1400 Timur pillaged it, and in 1517 it passed, with the rest of Syria, to the Ottoman dominion. But Ottoman jurisdiction was merely nominal in the Lebanon district, and Baalbek was really in the hands of the Metawali (see LEBANON), who retained it against other Lebanon tribes, until "Jezzar" Pasha, the rebel governor of the Acre province, broke their power in the last half of the 18th century. The anarchy which succeeded his death in 1804 was only ended by the Egyptian occupation (1832). With the treaty of London (1840) Baalbek became really Ottoman, and since the settlement of the Lebanon (1864) has attracted great numbers of tourists.



The ruins were brought to European notice by Pierre Belon in 1555, though previously visited, in 1507, by Martin von Baumgarten. Much damaged by the earthquake of 1759, they remained a wilderness of fallen blocks till 1901, when their clearance was undertaken by the German Archaeological Institute and entrusted to the direction of Prof. O. Puchstein. They lie mainly on the ancient Acropolis, which has been shored up with huge walls to form a terrace raised on vaults and measuring about 1100 ft. from E. to W. The Propylaea lie at the E. end, and were approached by a flight of steps now quarried away. These propylaea formed a covered hall, or vestibule, about 35 ft. deep, flanked with towers richly decorated within and without (much damaged by Arab reconstruction). Columns stood in front, whose bases still exist and bear the names of Antoninus Pius and Julia Domna. Hence, through a triple gateway in a richly ornamented screen, access is gained to the first or Hexagonal Court, which measures about 250 ft. from angle to angle. It is now razed almost to foundation level; but it can be seen that it was flanked with halls each having four columns in front. A portal on the W., 50 ft. wide, flanked by lesser ones 10 ft. wide (that on the N. is alone preserved), admitted to the Main Court, in whose centre was the High Altar of Burnt Sacrifice. This altar and a great tank on the N. were covered by the foundations of Theodosius' basilica and not seen till the recent German clearance. The Main Court measures about 440 ft. from E. to W. and 370 ft. from N. to S., thus covering about 3-1/2 acres. It had a continuous fringe of covered halls of various dimensions and shapes, once richly adorned with statues and columnar screens. Some of these halls are in fair preservation. Stairs on the W. led up to the temple of Jupiter-Baal, now much ruined, having only 6 of the 54 columns of its peristyle erect. Three fell in the earthquake of 1759. Those still standing are Nos. 11 to 16 in the southern rank. Their bases and shafts are not finished, though the capitals and rich entablature seem completely worked. They have a height of 60 ft. and diameter of 7-1/2 ft., and are mostly formed of three blocks. The architrave is threefold and bears a frieze with lion-heads, on which rest a moulding and cornice.
