The arrival of St. Patrick to the shores of Ireland dramatically changed the course of the indigenous culture and its art.
Contrary to popular belief, St. Patrick was not Irish. He was a Roman Britain, who was enslaved by Irish raiders and kept in captivity in Ireland for six years. He eventually escaped and returned to his home where he entered the Church and became a bishop. He believed it was his destiny to return to the Irish people and save them from their pagan ways.(1)
He is most famously known for driving the snakes out of Ireland. However, it is most likely that snakes never existed in Ireland due to its climate and its isolation from continental Europe. It is more likely that the snake represents the symbolism of the Druids and therefore the story relates to the country’s conversion from paganism to Christianity.
Another legend associated with St. Patrick tells of his use of the shamrock to describe the concept of the Holy Trinity. He used the structure of the plant, which has three leaves and one stem, to represent the idea of three beings in one God, the Father; the Son; and the Holy Spirit. This one example of symbolism has probably become the most potent icon of Irish representation the world over. But it is also a testament to the cleverness of St. Patrick in his efforts to convert the Irish pagans.
