Forseti is the god of justice and reconciliation in Norse mythology. He is generally identified with Fosite, a god of the Frisians. Jacob Grimm noted that if, as Adam of Bremen states, Fosite's sacred island was Heligoland, that would make him an ideal candidate for a deity known to both Frisians and Scandinavians, but that it is surprising he is never mentioned by Saxo Grammaticus.
