Fishburn and Hughes: "The name assigned to the author, or authors, of a chronicle of the Prankish Kingdom. This contained inter alia an abridged version of the History of the Franks in nine volumes by St Gregory, bishop of Tours (c.540-594) which reflected the orthodox Christian views of the bishop and his aversion to the Arian heresy. Fredegarius' chronicle appears in Migne's Patrology. CF 227: No record has been found of Fredegarius denying (together with Aristotle) God's 75 power to change the past" (74)
