Sulpicius Severus was a Christian writer and lawyer born in Aquitaine around 360. Originally a highly educated man of the Roman legal world, he was profoundly influenced by Saint Martin of Tours, which led him to abandon his worldly wealth and legal career to serve the poor and pursue a religious life. He is primarily remembered for his historical writings, including a significant chronicle of sacred history and a famous biography of Saint Martin, which remains a vital source for understanding the religious landscape of 4th-century Gaul.
