Maundy Thursday

Maundy Thursday is the day of the Last Supper in the book’s Christian account of the Holy Grail. In a vision before Galahad and his companions, Christ identifies the vessel as the dish from which he ate the lamb on that day, joining the Grail’s quest to the story of the Passion and the sacrament enacted in the vision.

The day and the vessel

The Grail’s identity is explained within a scene of sacred revelation. A bishop identified as Joseph of Arimathea appears before the silver table bearing the vessel; after a priestly rite, Christ emerges from it and gives the knights communion. He then tells Galahad that the holy dish was the one in which he ate the lamb on Maundy Thursday. The name also appears in the source’s form “Sher-Thursday.”

The Grail’s Christian history

The day’s significance belongs to a broader account of the Grail’s changing meaning. The introduction describes the Grail as a dish or drinking vessel and notes that earlier legends could portray it as a miraculous provider of food. In the Christian tradition presented there, it becomes either the dish used for the paschal lamb at the Last Supper, the vessel in which Joseph of Arimathea received Christ’s blood, or the sacramental cup itself. The story of Galahad makes the Last Supper identification explicit rather than leaving it as one tradition among several.

Revelation and departure

Christ’s identification of the dish is both a disclosure and a warning. Galahad has seen what he most desired, but Christ says that the vision will be more fully revealed in Sarras. The vessel is to leave Logris that night and will not be seen there again, because its people have turned to evil living and no longer serve or worship it rightly. The revelation thus connects Maundy Thursday’s sacred meal with the loss of the Grail from the kingdom and the quest’s movement toward its spiritual destination.
