What is "freculf"

Freculf (Freculphus Lexoviensis; died 8 October 850 or 852), a Frankish ecclesiastic, diplomat and historian, was a pupil of the palace school of Aachen during the reign of Charlemagne and Bishop of Lisieux from about 824 until his death. He is now best remembered for his universal chronicle, the Twelve Books of Histories (Historiarum libri XII), which is a source of information about the conversion of Gaul and the history of the Franks. Chronicles such as that of Freculf attempted to show world history from Creation to the present, but most history writing in the eighth and ninth centuries was considerably more local and specific.
