Prophecy of Melkin

The Prophecy of Melkin is a medieval text about an alleged hidden grave of Joseph of Arimathea at Glastonbury in England, containing the Holy Grail. It is contained in a local chronicle (Cronica sive antiquitates Glastoniensis ecclesiae) written by John of Glastonbury in the mid-14th century, who attributes it to an alleged Celtic bard named Melkin, said to have lived "before Merlin". It is thought to have been created in the context of legends that linked Joseph of Arimathea with the mythical Avalon, Glastonbury and the court of King Arthur, which had arisen in England in the mid-13th century.
