-Irish Blessing
Legend has it that Saint Patrick drove all the snakes out of Ireland -- that they all went into the sea and drowned. Poor snakes. I don't know why he would want to do this, except that the snake was a revered pagan symbol, and perhaps this was a figurative tale alluding to the fact that he drove paganism out of Ireland.
