Thorbjörg was a fortune-teller and that is why she was called the Sybil.  (Actually she was called “lítilvölva” which means “slim-sybil”). She had nine sisters that had all been fortune tellers, but Thorbjörg was the only one who was still alive.

During winter time Þorbjörg used to travel between farms and tell people their destiny, if they were ready to pay for her prediction which depende upon how curious people were and how much they would pay.

One day Thorkell Eiríksson invited Thorbjörg to his farm. Like what was customary  on farms where Thorbjörg came to visit, she was equipped a throne which cushions made of henfeathers.

The next morning when Thorbjörg was going to perform sorcery and predict for the people, she was wearing a blue womanovercoat with neckband and it was covered with stones. On her head she was wearing a black skullcap made of lamb-skin but inside it was white cat-skin and she also had some kind of a magical-stick which had an orb made of copper on the end. Thorbjörg was wearing a belt and on it hang a big pouch where she kept all her magical stuff that she needed to have for her soothsaying. She was also wearing some calf-skin shoes and some cat-skin gloves which were white and hairy inside. To perform the sorcery she had a knife with a broken tip. She also needed a woman to chant a heathen rune song called “Varðlokur”. Guðríður Thorbjarnardottir did that extremely well despite being a Christian woman.

When the sorcery had been done, Thorbjörg was payed and then she kept on her trip between farms in Greenland.
