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. 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.
A leprechaun (Irish: leipreachán) is a type of fairy in Irish folklore, usually taking the form of an old man, clad in a red or green coat, who enjoys partaking in mischief. Like other fairy creatures, leprechauns have been linked to the Tuatha Dé Danann of Irish mythology. The Leprechauns spend all their time busily making shoes, and store away all their coins in a hidden pot of gold at the end of the rainbow. If ever captured by a human, the Leprechaun has the magical power to grant three wishes in exchange for their release. Popular depiction shows the Leprechaun as being no taller than a small child, with a beard and hat, although they may originally have been perceived as the tallest of the mound-dwellers (the Tuatha Dé Danann).
