This Pope built two basilicas, first St. Lawrence's, near Pompey's Theatre, which he magnificently enriched, and endowed with houses and farms; and, secondly, another, over the Catacombs on the Ardeatine Way. He also consecrated the Platónia, where the bodies of St. Peter and St. Paul lay for some time, and decorated it with elegant inscriptions in poetry composed by himself. He wrote on the subject of virginity both in prose and verse, and likewise many other poems on various subjects.
He ordained that false accusers should be punished for the offences which they had falsely laid to the charge of their neighbours. He established the usage, which already prevailed in many churches, of singing the Psalms, both by day and by night, by alternate choirs, and of adding at the end of each Psalm the words, Glory be to the Father, and to the Son, and to the Holy Ghost. It was at his command that St. Jerome revised the translation of the New Testament to accord with the Greek text. He ruled the Church for seventeen years, two months, and twenty-six days. He held five Advent ordinations, wherein he ordained thirty-one Priests, eleven Deacons, and sixty-two Bishops for divers Sees. At length he fell asleep in the Lord, in the reign of Theodosius the Elder, aged nearly eighty years, and full of righteousness, truth, and judgment. He was buried beside his mother and sister in the Church which he had himself founded on the Ardeatine Way. His relicks were afterwards taken to the Basilica of St. Lawrence, which is thence sometimes called San Lorenzo in Damaso.
