Tilpin

Tilpin, Latin Tilpinus, also called Tulpin, a name later corrupted as Turpin, was the bishop of Reims from about 748 until his death. He was for many years regarded as the author of the legendary Historia Caroli Magni, which is thus also known as the "Pseudo-Turpin Chronicle". He appears as one of the Twelve Peers of France in a number of the chansons de geste, the most important of which is the Song of Roland. His portrayal in the chansons, often as a warrior-bishop, is fictitious.
