Turpin Tilpin
Turpin, or TILPIN, Archbiship of Rheims in the reign of Charlemagne, was long supposed to be the author of the De Vita Karoli Magni et Rolandi, descriptive of Charles's conquest of Spain and of the exploits and death of Roland. The work is now variously attributed to Pope Calixtus II and Aimeri Picaud. It is agreed by all critics that the date of composition cannot have been much before the beginning of the 12th century.
