Thorgil Sprakling (also called Torkel, Torgils or Sprakalägg) was a Dane whose grandsons became kings of Denmark and England. In Knýtlinga saga he is also called "the fast". Florence of Worcester named his father as 'Ursius' (i.e. urso, Latin for bear, björn in Scandinavian languages) and Saxo Grammaticus tells the story that this Ursius/Björn was the son of a bear and a fair Swedish maiden.
