Duke of Swales who, in Gottfriedís Tristan, harbored Tristan (Tristram) during one of Tristanís exiles from King Markís court. Gilan owned a little dog named Petitcrieu, which had been given to him by a lady from Avalon. He gave the dog to Tristan as a reward for Tristanís killing of the troublesome giant named Urgan.

He is known as Bramante in La Tavola Ritonda. In the Pleierís Garel, he appears as a knight defeated in combat by Garel. Each was so impressed with the otherís prowess that they became fast friends. Garel helped Gilan rescue his nephews, Alexander and Floris, from Eskilabon of Belamunt. Gilan returned the favor by fighting alongside Garel in Arthurís war against King Ekunaver of Kanadic. Arthur later awarded him a Round Table seat.
