Historically, the text is of interest primarily for materials relating to the Second 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.
