Explanation:

[STC006937] According to legend, Saint Patrick served as a Christian missionary in Ireland during the fifth century after the Common Era (CE). While he was there, he started a fast that was supposed to last for forty days but it was cut short when a number of snakes began attacking him. In response, Patrick began the complicated and enormous task of ridding Ireland of its entire serpentine population, which legend says was successful. There are no native snakes in Ireland, but it’s highly likely that this is because there were never any in the first place. For millennia, the fact that it is an island has protected it from ophidian colonization and maintained it free of ophidian life.
