Cei, Cai, Che, Kei. Sometimes with the patronymic ap Cynyr or vab Cynyr [son of Cynyr]. A character in Welsh Arthurian stories, a companion of
Arthur along with
Bedwyr, Cei is also the seneschal of Arthur's household and has a personality composed of unequal parts of courage and buffoonery. In the early poetry, such as the 12th-century
Black Book of Carmarthen, he appears to be a great and admirable hero. In the later romances, however, he descends into a surly steward characterized by cruel, sometimes ridiculous behaviour. Even in the later material he can still initiate action. He is clearly a model for Sir
Kay in English Arthurian narratives. See also
