The Monk of Malmesbury is the supposed author of a chronicle among the Cottonian manuscripts in the British Museum. The authorship is uncertain, and the work in question is said by some to be only a copy of a chronicle written by Alfred of Beverley in the twelfth century, while others claim it is almost entirely based on that of Geoffrey of Monmouth. It is a valueless compilation, describing English history from the invasion of the Saxons to the year 1129.
