Its funny that you mention that in the painting of the last supper there are no " cups." From what i have read the word Grail comes from the Latin
gradale which means "a dish brought to the table during various stages or courses of a meal."
So perhaps if the Grail existed at all it was not a cup or drinking vessel but the dish Jesus ate from at his last meal.
Over the years the Grail has taken many shapes and forms, Wolfram Von Eschenbach's Parzival portrays the Grail as a stone that gives sustenance and
prevents death.
The Grail legend didn't really become popular until the late 12th early 13th Century. It was brought into the Arthurian legend by Robert de Boron
when he wrote his Romance Joseph d'Arimathie sometime in the early 1300's. At the time the concept of Courtly love was coming into fashion and
Knights of the time were caught up in the whole Chivalry thing.
But i think the Grail, and this is my personal opinion, is a kind of metaphor for the ideals that the Knights of old Europe held so dear. Loyalty,
Chastity, Honour and sacrifice. If you read the Grail legends they are full of hardship, disappointment and sacrifice. The quest was the important
thing the journey of self discovery, of a Knight testing his endurance and skill by taking up the Quest for a Holy and magical object that always
seems to be just out of their reach. For the Knights of legend, Sir Perceval and Sir Galahad the quest for the Grail was a test of faith.
So perhaps the Grail does exist, not as an object but as an article of faith in the hearts of those who wish to believe.
