Celebrated: 18 Apr (Ireland)
He was born in Ireland, became a monk on Iona, and was ordained priest in Rome by St Gregory the Great. Returning to Ireland, he entered the monastery at Leighlin, of which he became abbot a few years before his death. He was active in promoting harmony between the Celtic and Roman churches, notably in the matter of the date on which Easter should be celebrated.
