Bishop. Patron of Paul in Cornwall. He is also known as Saint Pol de Leon. According to his Life written by Wrmonoc, a 10th century monk from Landevennec, he was the son of a Welsh chieftain who was educated at the monastery of St Iltyd. He became a monk, and together with 12 companions migrated to Brittany where they built a number of churches and monasteries.
He became bishop at Pol, which was named after him. St Paul Aurelian is said to have died at the age of 104 at his monastery on the island of Batz. There are several dedications to St Paul Aurelian in Wales and Brittany. An inscribed stone from the 6th century survives in Cynwyl Caeo.
The ancient church of Paul, near Penzance in Cornwall is dedicated to Pol de Leon.
