Saint Patrick was born in the fourth or fifth century AD and legend holds this saint drove all snakes out of Ireland. This legend likely arose from the credit to Saint Patrick for spreading Christianity in Ireland. He is known as the great ‘Apostle of Ireland’. St Patrick's patronages include protection from snake infestation and bites, and he is also a patron of engineers due to the large number of churches he constructed in Ireland. His feast day is celebrated on 17 March.
