Saint Patrick (Latin: Patricius; Proto-Irish: *Qatrikias; Modern Irish: Pádraig; Welsh: Padrig; c. 387 – 17 March c. 460 or c. 492) was aRomano-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. After becoming a cleric, he returned to northern and western Ireland as an ordained bishop, but little is known about the places where he worked. By the seventh century, he had already come to be revered as the patron saint of Ireland. St. Patties day = day of death (March 17th, ~457)
