Then Blaise went to get what he needed. And after he had looked for it and found it, Merlin began to recount the
love between Jesus Christ and Joseph of Arimathea, just as it had been, and to tell about Joseph and his offspring and those people who had the vessel called the Grail and all their accomplishments, just as they had been, of Alan and his companions, how he left his father’s house, how Petrus had departed, how Joseph disposed of his vessel, and how he died. Afterward he told him about the devils, how they had gathered together because they had lost the power they had enjoyed over humanity before, and he told him how the prophets had done them harm and how, for this reason, they had conspired to make a man. “And they said they would make me. You heard all about it and you learned from my mother and other people about their deeds and tricks—and then the foolishness they are all so full of, for they have lost me and every other advantage.”
