Irish mythology states that, before the Celts, there were five waves of invaders. One of the five being Cessair, who is said to be the granddaughter of Noah of Arch. Cassair chose to travel to Ireland after the flood because,”She thought it probable that a place where people had never come before, and where no evil or sin had been committed, and which was free from the world’s reptiles and monsters, that place would be free from the Flood.”
