Clegis
A Knight of the Round Table in the Alliterative Morte Arthure and Malory, perhaps influenced by Chrétien’s Cligés.
He participated in the Roman War. He joined Lancelot’s defection from Arthur’s court, helping him rescue Guinevere (Guenevere) from the stake and fighting in the battles against Arthur at Joyous Guard and Benoic (Benoye). In return for his support, Lancelot made him the Earl of Angen.
A knight of the same name appears in the non-Arthurian story Sir Cleges.
