The Liber Monstrorum (or Liber monstrorum de diversis generibus) is a late seventh-or early eighth-century Anglo-Latin catalogue of marvellous creatures,[1] which may be connected with the Anglo-Saxon scholar Aldhelm. It is transmitted in several manuscripts from the ninth and tenth centuries, but is often studied in connection with the better-known text Beowulf, since the Liber also mentions King Hygelac of the Geats and that he was renowned for his large size. Some scholars argue that the Beowulf-poet was in fact inspired by the Liber Monstrorum.[2] The book contains extraordinary people, such as Hygelac; some clearly historical reports of actual peoples, such as the Ethiopians; and some obviously mythological reports, such as the cyclopes and centaurs.
