Gaynus, Gayous, Quintilian, Quintilianus, Quencelin, Quyntalyn
A Roman warrior who was the nephew of the Roman Emperor Lucius.
At the beginning of the war between Arthur and Rome, Arthur sent Gawaine, Boso, and Guerin of Chartres (or Gawaine, Bors, Lionel, and Bedivere) as peace envoys to Lucius.
During the talks, however, Gaius Quintillianus remarked that Britons were more skilled at bragging and threatening than at battle. Gawaine, enraged at these comments, sliced off Gaius’s head, thus starting a battle and the war. Gawain later killed Marcellus Mucius, a friend of Gaius, and bade him to tell Gaius, when he met him in hell, that there were indeed no people who were better at bragging than the Britons.
The Vulgate Merlin calls him Titilus.
