And Arif - St Patrick is a Patron Saint of Ireland and one of the earliest Christian missionaries. He is credited with ridding Ireland of the snakes. The "snakes" are supposedly a reference to the Druids (paganism), rather than real snakes as there is little evidence that Ireland had real (slithering snakes) after the glaciers receded. He lived approximately between AD 387 & AD 461.
Thanks Isa for the updates!!
