The daughter of King Faramon of France.

She fell in love with Tristan while he was living and serving in Faramon's court. When Tristan did not reciprocate, she became enraged and staged a "rape" scene for which Tristan was convicted and sentenced to execution.

Governal, Tristan's tutor, pleaded the truth to Faramon, who in turn coaxed it from his daughter. Acquitted, Tristan left France, and Belide killed herself.
