Patron of St Levan (Cornwall) was probably a Welsh or Cornish saint of the 6th century.
He maybe the same as the Selevan or Selomon honoured in S. Brittany. A chapel on the cliff at St Levan, believed to be his hermitage, and a well, survive in a ruined state. A bench-end there, carved with two fish, preserves the memory of his fishing from the rocks, when once he found two bream on the same hook. He removed them both and returned them to the sea. Again they both came to the hook and again were cast into the sea. The same thing happened the third time: Selevan took them home and found his sister Breage had come to visit him with her two children. No date is provided for his feast by the Cornish Church Calendar. In Brittany, however, a King Selyf, often confused with Selevan, is venerated on 14 October.
