AURILLAC, ō̇′re′yȧk′ (probably from Aurelius, the Roman Emperor). A town of France, capital of the Department of Cantal (Auvergne), situated in a pleasant valley on the banks of the Jordanne, about 269 miles south of Paris (Map: France, J 7). It is said to owe its origin to a Benedictine monastery, founded in the Ninth Century, by Saint Géraud. The streets are wide but irregular, and are kept clean by streams supplied by a reservoir above the town and by a canal from the Jordanne. The neighboring quarries supply slates to cover the houses. The principal buildings of Aurillac are the churches of Notre Dame and Saint Géraud, the castle of Saint Etienne; the theatre; the college buildings, which contain a valuable public library; and the grain market. There is also a monument erected to the memory of the French philanthropist, M. de Montyon. Paper, jewelry, lace, copper utensils, leather, and lime are the chief industrial products. The English, in the Fourteenth and Fifteenth Centuries, often besieged the town, and it was frequently taken and pillaged during the religious wars in France in the Sixteenth Century. Pope Sylvester II., whose statue is to be seen at Aurillac, was born there, as was the infamous Carrier of the first French Revolution. Population, in 1896, 13,531.
AU′RIN (Lat. aurum, gold), C19H14O3. A coloring substance used in the manufacture of lacquers. It is obtained in the form of beautiful green needles, by the action of sulphuric and oxalic acids on carbolic acid at 130-150° C. Reducing agents transform it into a colorless substance known as leucarin, C19H16O3. Owing to the difficulty of fixing it, it is not much used as a dye, though its solution in alkali has a beautiful fuchsine red color.
AURISPA, ou-rē′spȧ, Giovanni (c.1369-1460). A distinguished Italian humanist of the Fifteenth Century, born at Noto, in Sicily, about 1369. In 1418 he went to Constantinople for the purpose of learning Greek; after some years he returned to Italy, bringing with him 238 manuscripts of ancient Greek authors, among them Pindar, Callimachus, Oppian, Æschylus, Sophocles, Plato, Plotinus, Xenophon, Lucian, Arrian, Dion Cassius, Diodorus Siculus, Strabo, and Procopius. On his return he lived at Venice, and later held the chair of Greek literature at Bologna. Niccolò de' Niccoli (q.v. ) was instrumental in calling him to Florence, where he replaced Guarino da Verona as teacher of Greek. But some disagreement cut short his stay in Florence, and he soon removed to Ferrara. In 1438, the Greek Emperor, John Palæologus, called him to assist in the council called by Pope Eugene IV.; the latter made Aurispa his secretary in 1441, which office he held for six years. He died at Ferrara in 1460. Of his many translations the following only have been published: Hierocles' Liber in Pythagoræ Aurea Carmina, Latinitate Donatus (Padua, 1474); Philisci Consolatoria, etc. (Paris, 1510). Many other translations remain in manuscript in Italian libraries. Consult: Voigt, Die Wiederbelebung des klassischen Alterthums, Vol. I. (Berlin, 1893); Symonds, Renaissance in Italy, Vol. II. (London, 1877).
