Palladius was the first bishop of the Christians of Ireland, preceding Saint Patrick. It is possible that some elements of their life stories were later conflated in Irish tradition. Palladius was a deacon and member of one of the prominent families in Gaul. Pope Celestine I consecrated him a bishop and sent him to Ireland "to the Scotti believing in Christ".

Ireland is an island in the North Atlantic Ocean, in north-western Europe. It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest in the world.
