Merlin and the Grail: Joseph of Arimathea, Merlin, Perceval: The Trilogy of Arthurian Prose Romances attributed to Robert de Boron

It is hard to overstate the importance of this trilogy of prose romances in the development of the legend of the Holy Grail and in the evolution of Arthurian literature as a whole.

They give a crucialnew impetus to the story of the Grail by establishing a provenance for the sacred vessel - and for the Round Table itself - in the Biblical past; and through the controlling figure of Merlin they link the story of Joseph of Arimathea with the mythical British history of Vortigern and Utherpendragon, the birth of Arthur, and the sword in the stone, and then with the knightly adventures of Perceval's Grail quest and the betrayal and death of Arthur, creating the very first Arthurian cycle.

Ambitious, original and complete in its conception, this trilogy - translated here for the first time - isa finely paced, vigorous piece of storytelling that provides an outstanding example of the essentially oral nature of early prose.
