 Even after these events, Metz cannot truly be said to have become the most powerful bishopric until the time of Arnulf.It is of some interest that the name of the diplomatically adept deacon of Gregory of Tours in 590 was also an Agilulf.The "Commemoratio Genealogiae Domni Karoli Glorissimi Imperatoris" written originally in the early 9th century states that Arnulf of Metz was the son of predecessor Arnoaldus of Metz, himself a son of Ansbertus and thus the Ferreoli of the Midi.
