'Burislav', 'Burisleif', 'Burysław' (d.
1008) is the name of a
mythical Wendish king from Scandinavian
sagas who is said to rule over Wendland. He is said to be father of
Gunhilda,
Astrid and
Geira. There are three possible hypotheses over his identity: first, that there actually was a Slavic prince of that name; second, that this was the name given by saga authors to any Slavic prince; third, that he is a compound person, combining two Polish rulers:
Mieszko I of Poland and
Boleslaus I of Poland.
