Gosaingot, Gosangos
Son of King Amant of Lambal (an enemy of Arthur) and ruler of Tharmadaise.
While marching to attack Arthur, Amant was slain by King Bors of Gannes, and Gosengos inherited Lambal. Gosengos and his seneschal, Nabunal, joined Arthur in opposing the Saxon invasion, and also in the war against Rome.
Arthur made him a Knight of the Round Table. He harbored a secret love for Guenevere, who, before her marriage to Arthur, had been infatuated with him.
