Look in it,' he said, smiling slightly, as you do when you have given someone a present which you know will please him and he is unwrapping it before your eyes.
I opened it. In the folder I found four 8×10 glossy photos, obviously professionally done; they looked like the kind of stills that the publicity departments of movie studios put out.
The photos showed a Greek vase, on it a painting of a male figure who we recognized as Hermes.
Twined around the vase the double helix confronted us, done in red glaze against a black background. The DNA molecule. There could be no mistake.
'Twenty-three or -four hundred years ago,' Fat said. 'Not the picture but the krater, the pottery.'
'A pot,' I said.
'I saw it in a museum in Athens. It's authentic. Thats not a matter of my own opinion; I'm not qualified to judge such matters; it's authenticity has been established by the museum authorities. I talked with one of them. He hadn't realized what the design shows; he was very interested when I discussed it with him. This form of vase, the krater, was the shape later used as the baptismal font. That was one of the Greek words that came into my head in March 1974, the word “krater”. I heard it connected with another Greek word: “poros”. The words “poros krater” essentially mean “limestone font”. '
There could be no doubt; the design, predating Christianity, was Crick and Watson's double helix model at which they had arrived after so many wrong guesses, so much trial-and-error work. Here it was, faithfully reproduced.
'Well?' I said.
'The so-called intertwined snakes of the caduceus. Originally the caduceus, which is still the symbol of medicine was the staff of- not Hermes-but-' Fat paused, his eyes bright. 'Of Asklepios. It has a very specific meaning, besides that of wisdom, which the snakes allude to; it shows that the bearer is a sacred person and not to be molested...which is why Hermes the messenger of the gods, carried it.'
None of us said anything for a time.
