Saint Placidus
Placidus was a disciple of Benedict of Nursia. He was the son of the patrician Tertullus, was brought as a child to Benedict at Sublaqueum and dedicated to God as provided for in chapter 69 of the Rule of St. Benedict.
Life
Placidus was the eldest son of the patrician Tertullus. When he was about eight years old, his father placed him under the care of Benedict at Subiaco, to be educated. Gregory the Great relates an account of Placidus being rescued from drowning by his fellow monk, Maurus, who, at Benedict's order, ran across the surface of the lake below the monastery and drew Placidus safely to shore. It appears certain that he accompanied Benedict when, about 529, he removed to Monte Cassino, which was said to have been made over to him by the father of Placidus.Of his later life nothing is known, but in an ancient psalterium at Vallombrosa his name is found in the Litany of the Saints placed among the confessors immediately after those of Benedict and Maurus; the same occurs in Codex CLV at Subiaco, attributed to the ninth century.
