Colmán Elo was a 6th-century Irish saint, poet, and bishop who was born in Glenelly, located in modern-day County Tyrone. A student of his uncle, Saint Columba, he established the monastery at Lynally, which led to his name being associated with the site. He later founded the Abbey of Muckamore and served as the Bishop of Connor. He is recognized in Irish hagiography as a significant religious figure and a notable early writer of Old Irish prose.
