GUIGAMBRESIL
Guingambresil, Guinganbresil

High steward or advisor to the kings of Escavalon, he enters Arthur's court during the questing fever inspired by the Loathly Damsel at the time of Percivale's second visit to court and rather puts a damper on things by charging Gawaine with treason in death of his master, the old King of Escavalon. Gawaine willingly pledges himself to meet his challanger within forty days at Escavalon in trial by combat before his alleged victim's father, the young king.

When next we see Guigambresil, he is returning to Escavalon, to find Gawaine and the young king's sister defending themselves against a mob. Guigambresil has known nothing until this moment of Gawaine's arrival, so it seems possible that Gawaine actually beat him back to Escavalon.

In any case, taking stock of the situation, Guigambresil hurries to find the young king and advise him that, since he has inwittingly made Gawaine his guest, he is obligated to see that no harm comes to him. We should surely understand Guigambresil as meaning "no harm before our combat"; nevertheless, his conduct looks wholly honorable. Whatever the story behind his accusation, I find it difficult to interpret Guigambresil as villainous. Arthur intervened, however, and the two knights made peace.

Guigambresil married Tancree, the niece of the king of Escavalon. Guigambresil's shield was gold with an azure band covering an exactly measured third of it.

In Wolfram’s Parzival, he is known as Kingrimursel. In the Livre d’Artus, Guinganbresil appears among Arthur’s forces in the Saxon wars. As in Perceval, he is hostile to Gawain, but because Gawain has slept with Florée, a maiden loved by Guinganbresil, as well as with Guinganbresil’s sister, begetting a child with each of them.
