INCIPIT.
Hear ye the history of the most holy vessel that is called Graal, wherein the precious blood of the Saviour was received on the day that He was put on rood and crucified in order that He might redeem His people from the pains of hell. Josephus set it in remembrance by annunciation of the voice of an angel, for that the truth might be known by his writing of good knights, and good worshipful men how they were willing to suffer pain and to travail for the setting forward of the Law of Jesus Christ, that He willed to make new by His death and by His crucifixion.
