Lancelot’s mother, according to Ulrich von Zatzikhoven.
She was the wife of King Pant (Ban) of Genewis (Gennewis). When the barons of Genewis overthrew and killed Pant, Clarine ran off, carrying the infant Lancelot, but a water fairy appeared and snatched the child away.
She returned to Genewis, where she enjoyed the protection of the noble Duke Aspyol until Lancelot returned many years later and claimed his ancestral property.
Clarine is probably a variation of Elaine, who is usually given as Lancelot’s mother.
