The Carmen de Hastingae Proelio (Song of the Battle of Hastings) is a 20th-century name for the Carmen Widonis, the earliest history of the Norman invasion of England from September to December 1066, in Latin. It is attributed to Guy, Bishop of Amiens, a noble of Ponthieu and monastically-trained bishop and administrator close to the French court, who eventually served as a chaplain for Matilda of Flanders, William the Conqueror's queen. Bishop Guy was an uncle to Guy I, Count of Ponthieu, who figures rather prominently in the Bayeux Tapestry as the vassal of Duke William of Normandy who captured Harold Godwinson, later to become King Harold II of England, in 1064.
