Biography
Information about the life of Saint Vincent is extremely scarce. The primary biographical source about him is the work "De viris illustribus" (On Illustrious Men) by Gennadius of Massilia, composed around 495 AD as a continuation of the work of the same name by Saint Jerome of Stridon.
Vincent was born in the city of Toul in the northeast of modern France. He was the blood brother of Saint Lupus of Troyes. After service in the army (Latin: secularis militia), he entered the Lérins Monastery of Saint Honoratus, where he was tonsured a monk. In 434, under the pseudonym Peregrinus, he wrote his most famous work, "Commonitorium". He reposed during the reign of the emperors Theodosius II and Valentinian III, i.e., in or before 450 AD. Vincent was highly esteemed by his contemporaries; for instance, Saint Eucherius of Lyon called him a holy man, outstanding in eloquence and knowledge.
