Maximus of Turin was a 5th-century Roman Christian prelate who served as the first bishop of Turin. Born in Volterra, he became a disciple of Ambrose of Milan and was appointed to his episcopal seat in 398. Throughout his leadership, he worked to strengthen the Christian faith in Northern Italy, notably participating in the consecration of Saint Patrick. He is remembered for his dual role as a dedicated theological writer and a protector of his community during periods of barbarian incursions.
