The
Gesta principum Polonorum is a
medieval gesta, or deeds narrative, concerned with Duke
Boleslaw III Wrymouth, his ancestors, and the Polish principality during and before his reign. Probably completed between 1112 and 1118, the extant text is present in three manuscripts with two distinct traditions. Its author, though anonymous, is traditionally called
Gallus, probably a non-Pole connected with the
monastery of Saint-Gilles or somewhere else in
western Europe.
