Jón lærði Guðmundsson (Icelandic pronunciation: [ˈjouːn ˈlairðɪ ˈkvʏðmʏntsɔn]; 1574–1658) was an Icelandic autodidact, poet, and alleged sorcerer.
Guðmundsson, who lived in Strandir, was considered a great master of magic in 17th century Iceland.
He was said to have turned around the Turkish slave ships from the coasts of Iceland more than once, an achievement which gave him widespread fame, and was described in popular prints.
[2] Guðmundsson wrote an unbiased report of the Slaying of the Spaniards and as a result was declared an outlaw in his own country.
