Maurin d'Agen was a sixth-century evangelist who worked within the Agenais region. Born in Agen to a Catholic family during the rule of the Visigoths, he studied under Saint Germain of Capua before returning home to preach. He was ordained as a levite and dedicated his life to spreading the Catholic faith. While preaching in Lactora, he defied local prohibitions against Catholic preachers, leading to his arrest and eventual execution by decapitation.
