Saint Patrick is one of the best known Christian religious figures in all of Ireland and a large part of Great Britain. Worldwide he is recognized for being the patron saint of the Irish land, along with Saint Columba and Saint Bridget. He was a Christian missionary who dedicated many years to God and preaching, in addition to writing texts in which he reflected on himself and the experiences that were added to his story every day. By tradition, he is considered to be the pioneer who introduced the Christian religion to Britain, as well as having accomplished a myriad of feats that border on the superhuman.
Two of the writings by Patrick of Ireland have survived to this day: the Confessio, a text in which he narrates his life and the journeys he made in his distant youth, and the Epistle ad milites Corotici, a letter addressed to the soldiers of Coroticus. Currently, the date and place of Saint Patrick's birth are unknown; however, various hypotheses, drawn from Confessio, identify him as a northern Briton. He was the son of Calpurnius, a Christian deacon who held land and some wealth, and a British woman named Concessa. His date of death is located between the years 461 and 493., in full old age.
This saint also popularized the symbol of the shamrock, since he used it to explain what the Holy Trinity was, claiming that the first leaf is the Father, the second the Son and the last the Holy Spirit. March 17 is an important date in Ireland, as it is celebrated on Saint Patrick's Day; although, it is celebrated on a smaller scale by the Irish community settled in other countries.
