I'm glad you answered this question Richard, because I've been digging to find the interview, or whatever it was, where you explained about the Elvis Museum. I had it in my mind that the photo was from a postcard! And I do still think there's an ancient Chinese story about a tortoise ...I've been skimming through my old school books trying to find it. All I've come up with is this passage from A.D.F. Kitto's book, The Greeks: There is a pleasing, though possibly libellous, story of a Chinese philospher who was asked what the earth rested on. 'A tortoise', said the philospher. 'And what does the tortoise rest on?' 'A table.' 'And what does the table rest on?' 'An elephant.' 'And what does the elephant rest on?' 'Don't be inquisitive.' ...but I swear there is a creation story involving a tortoise! Maybe there were thousands of outlandish creation stories in Chinese history, because in Buddhism there is no one widely accepted creation theory or story. Guess I gotta dig deeper ...go to the scary university library.
