Chościsko
Chościsko (Polish pronunciation: [xɔɕˈtɕiskɔ]) is a legendary figure in a Polish prehistory, father of Piast the Wheelwright, the founder of the Piast dynasty. His name occurs in the first Polish chronicle, Cronicae et gesta ducum sive principum Polonorum[1] by Gallus Anonymus, where the author refers three times to Piast as the son of Chościsko.
Chościsko's name is probably derived from a simplified pronunciation word Hastingsko derived from the term Hasding (word Hasding meant long-haired[2]) difficult to pronouncing in Old Slavonic. The other analysis suggests that Chościsko's name is probably derived from chost or chwost meaning tail in old Slavic.
