What is the story about St. Patrick driving the snakes out of Ireland?
In religious lore the snake (or serpent) represented evil, godlessness and the devil’s will (e.g., offering the apple to Adam). St. Patrick has been heralded as devoting his life to converting the pagans (or godless) to Christians. Thus, driving away evil. Symbolically this is shown as Patrick driving the “snakes” out of Ireland.
