Shortly before, among the gods, Angus Son of the Young, had stolen away Etain, the wife of Mider. He kept her imprisoned in a bower of glass, which he carried everywhere with him, never allowing her to leave it, for fear Mider might recapture her. The Gaelic Pluto, however, found out where she was, and was laying plans to rescue her, when a rival of Etain’s herself decoyed Angus away from before the pleasant prison-house, and set his captive free. But, instead of returning her to Mider, she changed the luckless goddess into a fly, and threw her into the air, where she was tossed about in great wretchedness at the mercy of every wind.
At the end of seven years, a gust blew her on to the roof of the house of Etair, one of the vassals of Conchobar, who was celebrating a feast. The unhappy fly, who was Etain, was blown down the chimney into the room below, and fell, exhausted, into a golden cup full of beer, which the wife of the master of the house was just going to drink. And the woman drank Etain with the beer.
But, of course, this was not the end of her—for the gods cannot really die,—but only the beginning of a new life. Etain was reborn as the daughter of Etair’s wife, no one knowing that she was not of mortal lineage. She grew up to be the most beautiful woman in Ireland.
When she was twenty years old, her fame reached the high king, who sent messengers to see if she was as fair as men reported. They saw her, and returned to the king full of her praises. So Eochaid himself went to pay her a visit. He chose her to be his queen, and gave her a splendid dowry.
It was not till then that Mider heard of her. He came to her in the shape of a young man, beautifully dressed, and told her who she really was, and how she had been his wife among the people of the goddess Danu. He begged her to leave the king, and come with him to his sídh at Bri Leith. But Etain refused with scorn.
“Do you think,” she said, “that I would give up the high king of Ireland for a person whose name and kindred I do not know, except from his own lips?”
The god retired, baffled for the time. But one day, as King Eochaid sat in his hall, a stranger entered. He was dressed in a purple tunic, his hair was like gold, and his eyes shone like candles.
The king welcomed him.
“But who are you?” he asked; “for I do not know you.”
“Yet I have known you a long time,” returned the stranger.
