The Coming of the Gael

And when they were hindered from land there by enchantments, they went sailing along the coast until they were at last able to make a landing at Inver Sceine .....

And there they were met by a queen of the Tuatha de Danaan, and a train of beautiful women attending on her, and her Druids and wise men following her. Amergin, one of the sons of Miled, spoke to her then, and asked her name, and she said it was Banba, wife of Mac Cuill, Son of the Hazel.

The went on then till they came to Slieve Eibhline, and there another queen of the Tuatha de Danaan met them, and her women and her Druids after her , and they asked her name, and she said it was Fodhla, wife of Mac Cecht, Son of the Plough.

They went on then till they came to the hill of Uisnech, and there they saw another woman coming towards them. And there was a wonder on them while they were looking at her, for in one moment she would be a wide-eyed most beautiful queen, and in another she would be a sharp-beaked, grey-white crow. She came on the where Eremon, one of the sons of Miled, was, and sat down before him, and he asked her who was she, and she said: "I am Eriu, wife of Mac Greine, Son of the Sun."

And the names of those queens were often given to Ireland in the after time.

But as to the Tuatha de Danaan, after they were beaten, they would not go under the sway of the sons of Miled, but they went away by themselves. And because Mananaan mac Lir understood all enchantments, they left it to him to find places for them where they would be safe from their enemies. So he chose out the most beautiful of the hills and valleys of Ireland for them to settle in; and he put hidden walls about them, that no man could see through, but they themselves could see through them and pass through them.

And he made of Feast of Age for them, and what they drank was the ale of Goibniu the Smith, that kept whoever tasted it from age and from sickness and from death. And for food at the feast he gave them his own swine, that though they were killed and eaten one day, would be alive and fit for eating again the next day, and that would go on in that way for ever.
