Founder of the Abbey and Diocese of Mayo, born in Connacht, c.605; died 8 August 676. He became a monk of Iona, and so famous were his virtues and learning, as testified by Saint Bede, that on the death of Saint Finan, in 661, he was appointed Bishop of Lindisfarne. During his brief episcopacy, the Synod of Whitby was held, in 664, as a result of which (Saint Colman being a determined protagonist of the old Irish computation), owing to the decision of King Oswy on the Paschal controversy, he resigned his see. Between the years 665 and 667 Saint Colman founded several churches in Scotland, and, at length, accompanied by thirty disciples, sailed for Ireland, settling down at Innisboffin, County Mayo, in 668. Less than three years later he erected an abbey, exclusively for the English monks in Mayo, subsequently known as “Mayo of the Saxons”. His last days were spent on the island of Innisboffin. His feast is celebrated 8 August.
