bishop. Reputedly consecrated bishop of Clogher by Patrick, Macartan was one of the earliest Irish saints with a reputation as a miracle-worker. Nothing is known of his life, but his grave at Clogher was venerated and earth was taken from it, as Bede records of others. The liturgical office in his honour is the only one to survive from an Irish source. A reliquary called the Great Shrine of St Mac Cairthinn, intended to contain relics of the Cross as well as of his bones, has been much altered over the centuries but survives as the ‘Domnach Airgid’. Feast: 24 March.
