Note 1 — Chapter V · OF THE TREACHERY OF KING JOHN
Reading edition
The real Turpin was, it would seem, Tilpin, Archbishop of Rheims from 754 to 794. We do not know that Tilpin was a warrior, but his predecessor, Milo by name, is said to have been a "warrior clerk," and as such to have been put into the archbishopric by Charles Martel.
