Gesta Herewardi

The Gesta Herewardi is the name of a Latin text probably written around 1109-31, recounting the deeds of Hereward the Wake. The Latin text of about 1109-31 claims to be a translation of an earlier (and now lost) work in Old English, with gaps in the damaged original filled out from oral history. The earliest surviving copy of the Gesta Herewardi is in a manuscript produced around the middle of the 13th century at Peterborough Abbey, along with other materials relating to the abbey. This 13th-century manuscript is known as the "Register of Robert of Swaffham".
