Saint Patrick was a Romano-British Christian missionary and bishop in Ireland. Known as the “Apostle of Ireland”, he is the primary patron saint of the island along with Saints Brigid and Columba. Two authentic letters from him survive, from which come the only generally accepted details of his life. When he was about 16, he was captured from his home and taken as a slave to Ireland, where he lived for six years before escaping and returning to his family.
