also called Eiriks Saga Rauda or Porfinns Saga Karlsefnis (Pordarsonar)
This is from Chapter 3 of the saga and details the visitation of a seeress to the home of Thorkel. She is not listed as using or practising runecraft, but is obviously held in high regard.
There was a woman there in the Settlement whose name was Thorbjorg; she was a seeress and was called the Little Sybil. She had had nine sisters, but now only she was left alive. It was Thorbjorgs practice of a winter to attend feasts, and those men in particular invited her to their homes who where curious to know their future or the seasons prospects. Because Thorkel was the leading householder there it was considered his responsibility to find out when these hard times which now troubled them would come to an end, so he invited her to his home, and a good reception was prepared for her, as was the custom when a woman of this kind was received. A high-seat was prepared for her, and a cushion laid down, in which there must be hens feathers.
When she arrived in the evening, along with the man who had been sent to escort her, this is how she was attired: she was wearing a blue cloak with strips which was set with stones right down to the hem; she has glass beads about her neck, and on her head a black lambskin hood lined inside with white catskin. She had a staff in her hand, with a knob on it: it was ornamented with brass and set around with stones just below the knob. Round her middle she wore a belt made of touchwood, and on this was a big skin pouch in which she kept those charms she needed for her magic. On her feet she had hairy calfskin shoes with lengthy, strong-looking thongs to them, and on the thong - ends big knobs of lateen. She had on her hands catskin gloves which where white inside and furry.
Now when she came inside everyone felt bound to offer her fit and proper greetings, which she received according as their donors found favour with her. Master Thorkel took the prophetess by the hand and led her to the seat which had been made ready for her. Thorkel then asked her to run her eyes over the household and herd and home too. She had little comment to make about anything.. During the evening tables where brought in, and what food was prepared for the seeress must now be told of. There was porridge made for her of goats beestings, and for her meat the hearts of all living creatures that where available there. She had a brass spoon and a walrus ivory handled knife mounted with a double ring of copper, with it's point broken off. Then where the tables where cleared away franklin Thorkel walked up to Thorbjorg and asked what she thought of the household there and men's state and condition, and how soon he would be informed as to the things he had asked her and which men wanted to know. She replied that she would have nothing to announce till the following morning, when she had slept there the night through.
But on the morrow, in the latter part of the day, she was fitted out with the apparatus she needed to perform her spells. She asked too to procure her such women as knew the lore which was necessary for performing the spell, and bore the name Vardlokur, Spirit Locks. But no such women were to be found, so there was a search made right through the house to find whether anyone was versed in these matters
"I am unversed in magic" was Gudrids reply "neither am I a prophetess, yet Halldis my foster mother taught me in Iceland the lore which she called Vardlokur"
"Then you are wiser than I dared hope" said Thorbjorg.
"But this is a kind of lore and proceeding I feel I cannot assist in," said Gudrid "for I am a Christian woman."
"Yet it might happen," said Thorbjorg "that you could prove helpful to people in this affair, and still be no worse a woman than before. Still I leave it to Thorkel to procure me the things I need here."
Thorkel now pressed Gudrid hard, till she said she would do as he wished. The women now formed a circle all round, while Thorbjorg took her seat up on the spell-platform. Gudrid recited the chant so beautifully and well than no one present cloud say he had ever heard the chant recited by a lovelier voice. The seeress thanked her for the chant, saying that she had attracted many spirits there who thought it lovely to lend ear to the chant - spirits 'who before wished to hold aloof from us, and pay us no heed. And now many things stand revealed to me which earlier where hidden from me as from others. And I can tell you that this famine will not last longer and that the season will mend when spring comes. The sickness which has long afflicted us, that too will mend sooner than was expected. As for you, Gudrid, I shall repay you here and now for the help we have derived from you, for your future is now an open book to me. You will make a match here in Greenland, the most distinguished there is, yet it will not prove of long duration; for your ways lie out to Iceland, where there will spring from you a goodly progeny, and over this progeny of yours shall a bright ray shine. And so, my daughter, farewell now, and happiness go with you.'
After this men approached the prophetess and inquired one by one about what they were most concerned to know. She was free with her information, and small part indeed of what she said failed to come true
