Chapter 1 HOW ASMUND THE PRIEST FOUND GROA THE WITCH
There lived a man in the south, before Thangbrand, Wilibald's son, preached the White Christ in Iceland. He was named Eric Brighteyes, Thorgrimur's son, and in those days there was no man like him for strength, beauty and daring, for in all these things he was the first. But he was not the first in good-luck.
Two women lived in the south, not far from where the Westman Islands stand above the sea. Gudruda the Fair was the name of the one, and Swanhild, called the Fatherless, Groa's daughter, was the other. They were half-sisters, and there were none like them in those days, for they were the fairest of all women, though they had nothing in common except their blood and hate.
Now of Eric Brighteyes, of Gudruda the Fair and of Swanhild the Fatherless, there is a tale to tell.
These two fair women saw the light in the self-same hour. But Eric Brighteyes was their elder by five years. The father of Eric was Thorgrimur Iron-Toe. He had been a mighty man; but in fighting with a Baresark, 
 who fell upon him as he came up from sowing his wheat, his foot was hewn from him, so that afterwards he went upon a wooden leg shod with iron. Still, he slew the Baresark, standing on one leg and leaning against a rock, and for that deed people honoured him much. Thorgrimur was a wealthy yeoman, slow to wrath, just, and rich in friends. Somewhat late in life he took to wife Saevuna, Thorod's daughter. She was the best of women, strong in mind and second- sighted, and she could cover herself in her hair. But these two never loved each other overmuch, and they had but one child, Eric, who was born when Saevuna was well on in years.
The mother of Swanhild the Fatherless was Groa the Witch. She was a Finn, and it is told of her that the ship on which she sailed, trying to run under the lee of the Westman Isles in a great gale from the north-east, was dashed to pieces on a rock, and all those on board of her were caught in the net of Ran  and drowned, except Groa herself, who was saved by her magic art. This at the least is true, that, as Asmund the Priest rode down by the sea-shore on the morning after the gale, seeking for some strayed horses, he found a beautiful woman, who wore a purple cloak and a great girdle of gold, seated on a rock, combing her black hair and singing the while; and, at her feet, washing to and fro in a pool, was a dead man. He asked whence she came, and she answered:
"Out of the Swan's Bath."
Next, he asked her where were her kin. But, pointing to the dead man, she said that this alone was left of them.
"Who was the man, then?" said Asmund the Priest.
She laughed again and sang this song:-
Groa sails up from the Swan's Bath, Death Gods grip the Dead Man's hand. Look where lies her luckless husband, Bolder sea-king ne'er swung sword! Asmund, keep the kirtle-wearer, For last night the Norns were crying, And Groa thought they told of thee: Yea, told of thee and babes unborn.
"How knowest thou my name?" asked Asmund.
"The sea-mews cried it as the ship sank, thine and others-and they shall be heard in story."
"Then that is the best of luck," quoth Asmund; "but I think that thou art fey."[ ]
[ ] I.e. subject to supernatural presentiments, generally connected with approaching doom.
"Ay," she answered, "fey and fair."
"True enough thou art fair. What shall we do with this dead man?"
"Leave him in the arms of Ran. So may all husbands lie."
They spoke no more with her at that time, seeing that she was a witchwoman. But Asmund took her up to Middalhof, and gave her a farm, and she lived there alone, and he profited much by her wisdom.
Now it chanced that Gudruda the Gentle was with child, and when her time came she gave a daughter birt
