Gargeloain

A lady loved by Tristan’s brother-in-law, Kahedin or Ruvalen, in one manuscript of the Prose Tristan and in Palamedes.

Tristan (Tristram) helps arrange a tryst between Gargeolain and his brother-in-law, for which Gargeolain’s husband, Bedalis, later tracked Tristan down and mortally wounded him with a poisoned lance. When Gargeloain saw her lover killed, she fell down dead.

Eilhart von Oberge tells the same story, calling the lady Gariole.
