The Carmen de Hastingae Proelio (Song of the Battle of Hastings) is an early written source for the Norman invasion of England from September to December 1066, in Latin; attributed to Bishop Guy of Amiens, uncle to Count Guy of Ponthieu, who figures rather prominently in the Bayeux Tapestry as the vassal of Duke William of Normandy who captured Harold Godwinson in 1064.
