Lambergus

In the Italian Tristano Riccardiano and La Tavola Ritonda, the husband of the Hebrew Damsel of Thornbush Ford.

He found out that his wife and Tristan were having an affair. When he challenged Tristan to combat, he lost. He was also cuckolded by a knight named Blanor or Brunoro, but Tristan returned the woman to Lambergus.

In the Prose Tristan, the same character is called Seguarades.

The author of Tavola may have confused him with Lambegue, a friend of Tristan in Tristan.
