duchy, but all were confiscated by the crown in consequence of the sentence which punished the constable's treason in 1527. The countship, however, had passed in 1422 to the house of La Tour, and was not annexed to the domain until 1615. The administration of the royal province of Auvergne was organized under Louis XIV. At the time of the revolution it formed what was called a “government,” with two divisions: Upper Auvergne (Aurillac), and Lower Auvergne (Clermont).

AUXANOMETER (Gr. αὐξάνειν, to increase, μέτρον, measure), an apparatus for measuring increase or rate of growth in plants.
AUXENTIUS (fl. c. 370), of Cappadocia, an Arian theologian of some eminence (see Arius). When Constantine deposed the orthodox bishops who resisted, Auxentius was installed into the seat of Dionysius, bishop of Milan, and came to be regarded as the great opponent of the Nicene doctrine in the West. So prominent did he become, that he was specially mentioned by name in the condemnatory decree of the synod which Damasus, bishop of Rome, urged by Athanasius, convened in defence of the Nicene doctrine (A.D. 369). When the orthodox emperor Valentinian ascended the throne, Auxentius was left undisturbed in his diocese, but his theological doctrines were publicly attacked by Hilary of Poitiers.
The chief source of information about him is the Liber contra Auxentium in the Benedictine edition of the works of Hilary.
AUXERRE, a town of central France, capital of the department of Yonne, 38 m. S.S.E. of Sens on the Paris-Lyon railway, between Laroche and Nevers. Pop. (1906) 16,971. It is situated on the slopes and the summit of an eminence on the left bank of the Yonne, which is crossed by two bridges leading to suburbs on the right bank. The town is irregularly built and its streets are steep and narrow, but it is surrounded by wide tree-lined boulevards, which have replaced the ancient fortifications, and has some fine churches. That of St Étienne, formerly the cathedral, is a majestic Gothic building of the 13th to the 16th centuries. It is entered by three richly sculptured portals, over the middle and largest of which is a rose window; over the north portal rises a massive tower, but that which should surmount the south portal is unfinished. The lateral entrances are sheltered by tympana and arches profusely decorated with statuettes. The plan consists of a nave, with aisles and lateral chapels, transept and choir, with a deambulatory at a slightly lower level. Beneath the choir, which is a fine example of early Gothic architecture, extends a crypt of the 11th century with mural paintings of the 12th century. The church has some fine stained glass and many pictures and other works of art. The ancient episcopal palace, now used as prefecture, stands behind the cathedral; it preserves a Romanesque gallery of the 12th century. The church of St Eusèbe belongs to the 12th, 13th and 16th centuries. Of the abbey church of St Germain, built in the 13th and 14th centuries, most of the nave has disappeared, so that its imposing Romanesque tower stands apart from it; crypts of the 9th century contain the tombs of bishops of Auxerre. The abbey was once fortified and a high wall and cylindrical tower remain. The buildings (18th century) are partly occupied by a hospital and a training college. The church of St Pierre, in the Renaissance style of the 16th and 17th centuries, is conspicuous for the elaborate ornamentation of its west façade. The old law-court contains the museum, with a collection of antiquities and paintings, and a library. In the middle of the town is a gateway surmounted by a belfry, dating from the 15th century. Auxerre has statues of Marshal Davout, J. B. J. Fourier and Paul Bert, the two latter natives of the town. The town is the seat of a court of assizes and has tribunals of first instance and of commerce, and a branch of the Bank of France. A lycée for girls, a communal college and training colleges are among its educational establishments. Manufactures of ochre, of which there are quarries in the vicinity, and of iron goods are carried on. The canal of Nivernais reaches as far as Auxerre, which has a busy port and carries on boat-building. Trade is principally in the choice wine of the surrounding vineyards, and in timber and coal.
Auxerre (Autessiodurum) became the seat of a bishop and a civitas in the 3rd century. Under the Merovingian kings the abbey of St Germain, named after the 6th bishop, was founded, and in the 9th century its schools had made the town a seat of learning. The bishopric was suppressed in 1790.
The countship of Auxerre was granted by King Robert I. to his son-in-law Renaud, count of Nevers. It remained in the house of Nevers until 1184, when it passed by marriage to that of Courtenay. Other alliances transferred it successively to the families of Donzy, Châtillon, Bourbon and Burgundy. Alice of Burgundy, countess of Auxerre, married John of Châlons (d. 1309), and several counts of Auxerre belonging to the house of Châlons distinguished themselves in the wars against the English during the 14th century. John II., count of Auxerre, was killed at the battle of Crécy (1346), and his grandson, John IV., sold his countship to King Charles V. in 1370.
AUXILIARY (from Lat. auxilium, help), that which gives aid or support; the term is used in grammar of a verb which completes the tense, mood or voice of another verb; in engineering, e.g. of the low steam power used to supplement the sail-power in sailing ships, still occasionally used in yachts, sealers or whalers; and in military use, of foreign or allied troops, more properly of any troops not permanently maintained under arms. In the British army the term “Auxiliary Forces” was employed formerly to include the Militia, the Imperial Yeomanry and the Volunteers.
AUXIMUM (mod. Osimo), an ancient town in Picenum, situated on an isolated hill 8 m. from the Adriatic, on the road from Ancona to Nuceria. It was selected by the Romans as a fortress to protect their settlements in northern Picenum, and strongly fortified in 174 B.C. The walls erected at that period, of large rectangular blocks of stone, still exist in great part. Auximum became a colony at latest in 157 B.C. It often appears in the history of the civil wars, owing to its strong position. Pompey was its patron, and intended that Caesar should find resistance here in 49 B.C. It appears to have been a place of some importance in imperial times, as inscriptions and the monuments of its forum (the present piazza) show. In the 6th century it is called by Procopius the chief town of Picenum, Ancona being spoken of as its harbour. (T. As.)
AUXONNE, a town of eastern France, in the department of Côte d'Or, 19 m. E.S.E. of Dijon on the Paris-Lyon railway to Belfort. Pop. (1906) 2766 (town); 6307 (commune). Auxonne is a quiet town situated in a wide plain on the left bank of the Saône. It preserves remains of ramparts, a stronghold of the 16th century flanked by cylindrical towers, and a sculptured gateway of the 15th century. Vauban restored these works in the latter half of the 17th century, and built the arsenal now used as a market. The church of Notre-Dame dates from the 14th century. Of the two towers surmounting its triple porch only that to the south is finished. A lofty spire rises above a third tower over the crossing. The hôtel de ville (15th century) and some houses of the Renaissance period are also of architectural interest. A statue of Napoleon I. as a sub-lieutenant commemorates his sojourns in the town from 1788 to 1791. Auxonne has a tribunal of commerce and a communal college. Its industries are unimportant, but it has a large trade in the vegetables produced by the numerous market gardens in the vicinity.
Auxonne, the name of which is derived from its position on the Saône (ad Sonam), was in the middle ages chief place of a countship, which in the first half of the 13th century passed to the dukes of Burgundy. The town received a charter in 1229 and derived some importance from the mint which the dukes of Burgundy founded in it. It was invested by the allies in 1814, and surrendered to an Austrian force in the following year.
