Clarus of Vienne was a 7th-century Benedictine abbot born around 590 in Beauchamp. After being raised by monks at the Saint-Ferréol monastery, he eventually served as the abbot of Saint-Marcel and as a chaplain at Sainte-Blandine. Known for his religious devotion, he was believed to possess the gifts of prophecy and healing. He died in Vienne around 660 and was interred at the Sainte-Blandine church, though his relics were later lost during the Wars of Religion.
