Life

Saint Derien (Derrien, Drien), a contraction of Adrian, is a Breton saint venerated in the Léon region. He is known only from the Life of Saint Rioc, preserved by Albert le Grand from lost manuscripts, and it is not clear how much of it is historical. According to these accounts, he and Saint Neventer were two British colonists settled in Léon north of the River Elorn, in the fifth or the seventh century; both served the lord of La Roche-⁠Maurice and freed him from a dragon. He is commemorated on 14 February and is counted among the half-⁠legendary Breton saints.
