Pope Damasus I (305 – 11 December 384), also known as Damasus of Rome, was the bishop of Rome from October 366 to his death in 384. He presided over the Council of Rome of 382 that determined the canon or official list of sacred scripture. Damasus spoke out against major heresies (including Apollinarianism and Macedonianism), thus solidifying the faith of the Catholic Church, and encouraged production of the Vulgate Bible with his support for Jerome. He helped reconcile the relations between the Church of Rome and the Church of Antioch, and encouraged the veneration of martyrs.
As well as various prose letters and other pieces Damasus was the author of Latin verse.
