The Holy Grail
The quest for the Holy Grail is well-known in Arthurian legend. The Grail was said to be the cup of the Last Supper; the final meal that Jesus shared with his disciples in Jerusalem before his crucifixion. According to myth, it was brought to Britain by Joseph of Arimathea, where it lay hidden for centuries.
The search for the all-powerful Grail became the most important quest of the knights of King Arthur. It was believed to be kept in a mysterious castle surrounded by a wasteland and protected by the Fisher King, who suffered from a wound that would not heal. His recovery, and the renewal of his ruined land, depended upon the knight who would successfully complete the quest to find the Grail.
Long before medieval writers introduced the Holy Grail, the quest for magical grails appeared in the stories of Celtic myth, such as the tale of Culhwch and Olwen in the Mabinogion.
