Legends do, of course, get somewhat distorted in the passage of time. In the future, the passage across space to other planets may cause a slight modification here and there ?
President O'Hanrahan of the planetary government of Eire listened unhappily to his official guest. He had to, because Sean O'Donohue was chairman of the Dail-of Eire on Earth-Committee on the Condition of the Planet Eire. He could cut off all support from the still-struggling colony if he chose. He was short and opinionated, he had sharp, gimlet eyes, he had bristling white hair that once had been red, and he was the grandfather of Moira O'Donohue, who'd traveled to Eire with him on a very uncomfortable spaceship.

St. Patrick drove them out. What sets this world apart from all the other livable planets men have put down their smelly spaceships on? There's no snakes here! St. Patrick has great influence up in Heaven. He knew his fine Erse people would presently need more room than there was on Earth for them. So he'd a world set aside, and marked by the sign that no least trace of a serpent could exist on it. No creature like the one that blarneyed Mother Eve could be here! No--"
