Repanse de Schoye
The Grail bearer in Wolfram’s Parzival.
She was the daughter of Frimutel, the sister of Anfortas, Trevrizent, Schoysiane, and Herzeloyde (Herselojde), and the aunt of Perceval.
As a maiden, Repanse had charge of the Grail and carried it in the Grail Procession. After Perceval became the Grail King, Repanse fell in love with Feirefiz, Perceval’s pie-bald half brother, at Arthur’s court. Repanse and Feirefiz married and moved to India, where they became the parents of Prester John.
