Gwevyl

Gwewyl

A warrior, and son of Gwestad.

A seldom listed member of the expeditionary force led by Culhwch on his quest to locate the maiden Olwen.

Gwevyl was chosen as he was able, when sad, to

let one of his lips drop below his waist, while he turned upon the other like a cap upon his head.
