Latuinus was a 5th-century presbyter who is recognized as the first bishop of Sées. While some historical accounts place his leadership between 400 and 440 AD, different traditions offer varying origins for his mission. Some narratives suggest he was a 1st-century missionary sent by Pope Clement I, while others claim he arrived under the direction of Boniface I. Regardless of these conflicting timelines, he is honored as a saint within the Roman Catholic Church.
