In the later romances, the Holy Grail is a Christian relic of marvellous potency. It had held the Paschal lamb eaten at the Last Supper;[500] and, after the death of Christ, Joseph of Arimathea had filled it with the Saviour’s blood.[501] But before it received this colouring, it had been the magic cauldron of all the Celtic mythologies—the Dagda’s “Undry” which fed all who came to it, and from which none went away unsatisfied;[502] Brân’s cauldron of Renovation, which brought the dead back to life;[503] the cauldron of Ogyrvran the Giant, from which the Muses ascended;[504] the cauldrons captured by Cuchulainn from the King of the Shadowy City,[505] and by Arthur from the chief of Hades;[506] as well as several other mythic vessels of less note. In its transition from pagan to Christian form, hardly one of the features of the ancient myth has been really obscured. We may recount the chief attributes, as Taliesin tells them in his “Spoiling of Annwn”, of the cauldron captured by Arthur. It was the property of Pwyll, and of his son Pryderi, who lived in a kingdom of the other world called, among other titles, the “Revolving Castle”, the “Four-cornered Castle”, the “Castle of Revelry”, the “Kingly Castle”, the “Glass Castle”, and the “Castle of Riches”. This place was surrounded by the sea, and in other ways made difficult of access; there was no lack of wine there, and its happy inhabitants spent with music and feasting an existence which neither disease nor old age could assail. As for the cauldron, it had a rim of pearls around its edge; the fire beneath it was kept fanned by the breaths of nine maidens; it spoke, doubtless in words of prophetic wisdom; and it would not cook the food of a perjurer or coward.[507] Here we have considerable data on which to base a parallel between the pagan cauldron and the Christian Grail.
