Bishop of Mayo, an English monk, date of birth unknown; died 13 March 731; followed Saint Colman, after the Synod of Whitby (664), to Ireland, and settled in Innisboffin, in 668. Dissensions arose, after a time, between the Irish and the English monks, and Saint Colman decided to found a separate monastery for the thirty English brethren. Thus arose the Mayo (Magh Eo, the yew plain), known as “Mayo of the Saxons”, with Saint Gerald as the first abbot, in 670. Saint Bede writes: “This monastery is to this day (731) occupied by English monks … and contains an exemplary body who gathered there from England, and live by the labour of their own hands (after the manner of the early Fathers), under a rule and canonical abbot, leading chaste and single lives.” Although Saint Gerald was a comparatively young man, he proved a wise ruler, and governed May until 697, when, it is said, he resigned in favour of Saint Adamnan. Some authors hold that Saint Adamnan celebrated the Roman Easter at Mayo, in 703, and then went to Skreen, in Hy Fiachrach, and that after his departure the monks prevailed on Saint Gerald to resume the abbacy. The Saxon saint continued to govern the Abbey and Diocese of Mayo till his death. His feast is celebrated on 13 March. Mayo, though merged in Tuam for a time, remained a separate see until 1579.
