Robert of Gloucester wrote a chronicle of British, English, and Norman history sometime in the mid or late thirteenth century. The Chronicle survives in some 16 manuscripts, ranging in date from the early fourteenth to mid-fifteenth centuries, and was of considerable interest to contemporaries and antiquarian scholars. It wasn't until after the editing of the text by William Aldis Wright that its neglect - "worthless as history" and "verse without one spark of poetry" according to its editor - became widespread. Historically, the text is of interest primarily for materials relating to the Barons' War, to which the author (or an author of a portion of the text) seems to have been a witness. The first part of the Chronicle translates materials from Geoffrey of Monmouth's Historia regum Britanniae, narrating fabulous British history. The majority of English/Anglo-Saxon history is compiled from the works of Henry of Huntingdon and William of Malmesbury, and the post-Conquest portions are translated from numerous sources densely interwoven with original text.
