The word "grail" is derived from an Old French term, "greal", meaning a kind of dish. Is it too far offbase to imagine it as a bowl?

The earliest hero of the Grail story was Perceval, who failed to achieve the Grail at first because he didn't ask the Grail questions ("What is the grail? Whom does it serve?")- thereby restoring the Maimed King (sometimes but not always identified with the FISHER KING) to health and the land round about to fertility (Illustrated Encyclopedia of Arthurian Legends).

Now, in my opinion, the Grail questions somewhat resemble Elayne and Nynaeve's use of "need" to find the Bowl of Winds (LOC 13). (I admit this is a tentative connection, but it does exist.)

And we know that Rand represents the Fisher King (PoD Prologue) because of Moridin's little game of sha'ra (although the Maimed King and the Fisher King are not always identified with each other, they often are, and in this case they are identical given the wounds).

Also, one of the Prophecies of the Dragon ties the health of the land to that of the Dragon. "There can be no health in us, nor any good thing grow, for the land is one with the Dragon Reborn, and he one with the land." (CoS Prophecy Header) It isn't that farfetched to imagine that Rand's wounds MIGHT heal with the alteration in the weather patterns, although it is just as easy to conclude that Rand's wounds are what was affecting the weather in the first place and not the other way around. (This is beginning to resemble the chicken and the egg argument, because we can't really say what is cause and what is effect, due to insufficient information.)

Could the Bowl of Winds be a parallel to the Holy Grail of Arthurian legend?
