Andeolus or Andéol was born in Smyrna in the 2nd century. A subdeacon, he was sent by Polycarp, along with Benignus, to evangelize southern Gaul. He went to the Vivarais. Septimius Severus, passing through that region, had him put to death. His head was stabbed with a gladius on May 1, 208, at Bergoiata, a Gallic settlement on a rocky peak over the Rhône River which would be later known as Bourg-Saint-Andéol.
