Melaine was a 6th-century bishop of Rennes, serving the region of Brittany in what is now France. Born to a Gallo-Roman family near Redon, he initially lived as a monk and founded a small monastery. He eventually succeeded Bishop Amand, a transition that local traditions suggest he accepted with significant hesitation. During his tenure, he served as a counselor to Clovis and participated in the First Council of Orléans in 511.
Life and service

As a religious leader, Melaine worked to suppress pagan customs and acted as a trusted advisor to Clovis. He was known for his opposition to certain migrations from Britain. Following his death near the Vilaine river, his remains were reportedly transported to Rennes by a boat that moved against the current without human or wind assistance.
Veneration and legacy

He is the primary patron saint of the Diocese of Rennes, where an abbey church was dedicated in his honor. His sanctity was reinforced by stories of his tomb surviving a fire. Melaine is commemorated on 6 November, though some traditions in the Diocese of Quimper and parts of Wales observe his feast on different dates.
