As pope, St. Damasus I (†384) commissioned his secretary, St. Jerome, to revise the Latin Bible in use at that time by translating the Old Testament from the Hebrew rather that the Greek version. The Vulgate remained the standard Latin translation until 1979. Damasus presided over the Council of Rome, at which the canon of Scripture, or recognized books in the Bible, was set. He fought to counteract Apollinarianism, an overcorrection to Arianism that de-emphasized Christ’s humanity. He is also known for the verses he composed to adorn the tombs of the martyrs in Rome.
