Basilius
Primus. Vetus Glossarium San-German. n. 501.
(Βασίλειος). (1) A Christian writer, surnamed the Great, of Caesarea in Cappadocia. He was born of a noble family in A.D. 329, was educated in rhetoric at Constantinople and Athens by Libanius and Himerius, and subsequently took up the profession of advocate. But it was not long before he dedicated himself to the service of the Church. He distinguished himself especially by his resistance to Arianism and the measures he adopted for regulating the monastic system. He died, the bishop of his native city, in A.D. 379. He composed a revised liturgy still in use in the East, and known as the “Liturgy of the Holy Basil.” Besides his writings on points of doctrine, we have an address by him to young men on the uses of Greek literature, the study of which he earnestly recommended, in opposition to the prejudices of many Christians. He has also left a collection of four hundred letters, which are models in their way. Among them are those addressed to Libanius, his pagan instructor. A standard edition of his works is that of the Abbé Migne in 4 vols. (29-32) of his Patrologia Graeco-Latina (Paris, 1866). The Greek Church celebrates the day of his death (January 1st), the Roman Church that of his ordination (June 14th).
(2) The name of several of the Byzantine emperors. See Byzantinum Imperium.
