the Round Table in imitation of the table of the Last Supper and of Joseph of Arimathea's Grail Table. Made of silver, the Grail Table was used by the followers of Arimathea after he created it as directed by a vision of Christ, and was taken by him to Avalon (later identified with Glastonbury Tor, but this connection was not mentioned by Robert). This version of the Round Table, here made for Arthur's father Uther Pendragon rather than Arthur himself, has twelve seats and one empty place to mark the betrayal of Judas; this seat, must remain empty until the coming of the knight who will achieve the Grail. The Didot Perceval, a prose continuation of Robert's work, takes up the story as the knight Perceval sits in the seat and initiates the Grail quest. The prose cycles of the 13th century, the Lancelot-Grail (Vulgate) Cycle and the Post-Vulgate Cycle, further adapt the chivalric attributes of the Round Table but make it and its fellowship much larger, with many more seats and usually dozens of members at any given time. Here it is the perfect knight Galahad, rather than Percival, who assumes the empty seat, now called the Siege Perilous. Galahad's arrival marks the start of the Grail quest as well as the end of the Arthurian era. In these works the Round Table is kept by King Leodegrance of Cameliard after Uther's death; Arthur inherits it when he marries Leodegrance's daughter Guinevere. Other versions treat the Round Table differently, for instance Arthurian works from Italy like La Tavola Ritonda (The Round Table) often distinguish between the knights of the "Old Table" of Uther's time and those of Arthur's "New Table". In the Post-Vulgate, the Table is eventually destroyed by King Mark during his invasion of Logres after the deaths of Arthur and almost all of the Knights, many of whom in fact had killed each other, especially in internal conflicts at the end of the cycle. Round Table tournaments During the Middle Ages, festivals called Round Tables were celebrated throughout Europe in imitation of Arthur's court. These events featured jousting, dancing, and feasting, and in some cases attending knights assumed the identities of Arthur's entourage. Winchester Round Table The Winchester Round Table is a large tabletop hanging in Winchester Castle and bearing the names of various knights of Arthur's court, was probably created for a Round Table tournament.
