Simplicius of Vienne

Saint Simplicius of Vienne, otherwise Simplides, was a bishop of Vienne in the Dauphiné, France, from around the end of the fourth century and the beginning of the fifth century. He is venerated as a saint of the Catholic Church.
Simplicius apparently attended the Council of Turin which probably took place in either 398 or 400.
Gregory of Tours cites a lost letter of Paulinus of Nola as having praised Simplicius, considering him "one of the most worthy bishops of his time".
His feast day is celebrated on 11 February.
