Simeu, Symeon, Symeu, Symon
A follower of Joseph of Arimathea who was not pure.
At a dinner, he was one of only two followers that the Grail would not serve. In envy, he attacked his cousin Peter, one of Joseph’s pious followers, and badly wounded him. The other followers decided to bury him alive, but before they could perform the task, he was carried away in flames to a tomb in Wales, where he was destined to remain, in agony, until the Grail Quest.
Lancelot found the tomb and tried to free him but failed. When Galahad approached, the flames disappeared and Simeon was allowed to die. His son, Moses, also sinned and had to be freed by Galahad.
