- Clear (translation of his name)
Bishop of Marseille, France c.595. Correspondent with Saint Gregory the Great; four of their letters have survived and provide what little we know about Serenus. He questioned the use of sacred images, and destroyed some icons in his cathedral to stop what he considered a tendency to idolatry, especially by people who came from outside the port city, but Pope Gregory convinced him of their value in catechising the illiterate. Assisted Saint Augustine of Canterbury on his mission to England in 596. Died while returning to Marseille from a visit to Rome, Italy.
