Damasus I

c.304-384. Pope from 366. Born in Rome of Spanish parentage, he succeeded Liberius in the papacy, but was established only after Emperor Valentinian I came to his support and forcibly suppressed supporters of Ursinus, set up as a rival pope. Under the pontificate of Damasus, Apollinarianism and Macedonianism were condemned (368, 369), the famous Tome of Damasus* was issued (382), an imperial decree against clerical worldliness was enforced, and Jerome (then his private secretary) was commissioned by Damasus to revise the Latin translations of the Bible, the outcome of which was the Vulgate.
