I really doubt the cup that Christ had at the last supper would be ornate. I think that is a fake.
IMO it was probably a simple cup, because Christ was a simple Rabbi on earth, not an earthly king.
The Grail is one of those funny fascinations of mine. If I remember right, that particular cup has a lot of extra stuff gilded on to the bottom. The only "real" portion would be the stone cup on the top.
Which would make sense, since stoneware was considered impossible to make unclean, it was very popular around the first century.
Tres cool.
Y'know, I was thinking earlier how many people would never belive the stone portion to be the Grail.
Many don't belive in the shroud or the sudarium or the Tilma or Lanciano or Fatima. People can come up with all sorts of explanations or excuses for why not. We more readily believe that it is a fraud rather than the Lord God who created everything could preserve some material article. We talk about faith but do we really belive in anything beyond what man can do? So many so little faith.
Oh well, I'm tired.
