covered with little plates of glass,” she said. “Those are held on with lead nails. One of the boys swam over and had a look for me. The people here knew how to make fine glass!”
    Her father, sitting with his back to the cool stone, gave a nod. “That is quite likely. Many cultures make glass. We have the beginnings of a hypothesis, but you need to find your lens maker.”
    “Papa, it stands to reason that sooner or later a glassmaker would notice a bubble in the glass and see how the light—”
    But her father had held up a hand. “Science is not interested in what ‘stands to reason,’” he said. “It ‘stands to reason’ that the Earth is flat. What we know is that the Romans took some interest in crude lenses, and that eyeglasses were not invented until the thirteenth century. The Italian Salvino D’Armate is generally credited with—”
    “Why is it always so, so…northern hemisphere?” said Daphne. “Turn the world upside down!” She pulled her father over to the wall near the globe and pointed to a panel. “You remember I told you they were very keen on showing hands holding things, too?” she said, and held up the lamp. “There! Doesn’t that look like a pair of spectacles to you?”
    He looked at the panel critically, like a man trying to decide between cake and pie.
    “It could be,” he said, “but it could be a mask, or scales, or have some mysterious religious significance. It doesn’t help you much, I’m sorry to say.”
    Daphne sighed. “Look, if I found some evidence that they knew about lenses, would you accept they may have known how to build a telescope?”
    “Yes, that would be reasonable. I won’t accept that they did , mind you, only that they may have done so.”
    “Come and see.”
    This time she led him to the other side of the gods, to a niche in the wall where the white panel had fallen out.
    “One of the boys found them in silt at the bottom of the god pool. The glass is broken on one side and the other is cracked, but you can see they were lenses. Be careful.” She laid them carefully in his hand.
    He blinked. “Gold-rimmed spectacles…” But he breathed the words rather than said them.
    “Have I proved my telescope theory, Papa?” she said gleefully. “We know that eyeglasses lead on to telescopes.”
    “Once before, at least. Or since, I’m sure you would say. Why didn’t you show me these straightaway?”
    “I just wanted to make you admit I was doing proper science!”
    “Well done,” said His Excellency. “You have built a very strong hypothesis indeed, but I’m sorry to say that you have not proved the full theory. You’d need to find the telescope for that.”
    “That’s unfair!” said Daphne.
    “No, it’s science,” said her father. “‘Could have’ isn’t good enough. Nor is ‘might have’! ‘Did’ is the trick. But when you announce this, a lot of people will try to prove you wrong. The more they fail, the more right you will become. And they will probably try to suggest that some European traveler came here and lost his eyeglasses.”
    “And his false teeth made of gold?” snapped Daphne. She told him about Mrs. Gurgle’s proudest possession.
    “I would very much like to see them. Some people will find them easier to accept. Don’t be discouraged about the telescope. What is clear is that this place was the home of a hitherto unknown seafaring culture that was very adept in the technical arts. Good heavens, my girl, most people would be ecstatic to have discovered all this!”
    “I didn’t,” said Daphne. “Mau did. I just had to look over his shoulder. He had to walk past a hundred thousand ancestors. This is their place, Papa. Their ancestors built it. And put on the globe there the symbol of a wave breaking in front of the setting sun, which every man of the islands has worn as a tattoo for thousands of years. I saw it! And you know what? I can prove that no European has been into this cave before me.” Daphne looked around, chest heaving with passion. “See the gold on the gods and the globe and the big door?”
    “Yes. Of course, dear. I could hardly fail to notice.”
    “There you are, then,” said Daphne, picking up the lamp. “It’s still here !”
     
    Mau sat with one of the Judy ’s charts on his knees. This was, officially, a meeting of the island council, or would have been if anything on the island was official. Anyone could come, and because anyone could, many didn’t. There were
