Galdra-Manga

Margrét Þórðardóttir, known in history under her sobriquet Galdra-Manga ('Manga of the Spells'; fl. 1662) was an Icelandic woman, known for being persecuted for witchcraft. She has been referred to as one of only two women executed for sorcery in Iceland (alongside Thuridur Olafsdottir) and are the subject of a folktale.

She was the daughter of Þórður Guðbrandsson, one of the executed in the Kirkjuból witch trial in 1656. She was persecuted for witchcraft because of her father, and famously fled from the court until she was finally apprehended and put on trial in 1662. On the trial, she was condemned to death and executed as one of only two women in Iceland to have been so. Another version, however, claims that she was acquitted. Because documentation is lacking, the verdict of the trial and her subsequent fate is unknown.
