one side they could see the entire city, and swampy Lake Mareotis and the dusty Egyptian plain beyond it, and from the other they peered far out into the gray and choppy Mediterranean. He gestured toward the innumerable reefs and shallows that infested the waters leading to the harbor entrance. “No wonder they needed a lighthouse here,” he said. “Without some kind of gigantic landmark they’d never have found their way in from the open sea.”
A blast of sound, a ferocious snort, erupted just above him. He looked up, startled. Immense statues of trumpet-wielding Tritons jutted from the corners of the Lighthouse at this level; that great blurting sound had come from the nearest of them. A signal, he thought. A warning to the ships negotiating that troubled passage. The sound was produced by some kind of steam-powered mechanism, he realized, operated by teams of sweating temporaries clustered about bonfires at the base of each Triton.
Once again he found himself swept by admiration for the clever way these people carried out their reproductions of antiquity. Or were they reproductions, he wondered? He still did not understand how they brought their cities into being. For all he knew, this place was the authentic Alexandria itself, pulled forward out of its proper time just as he himself had been. Perhaps this was the true and original Lighthouse, and not a copy. He had no idea which was the case, nor which would be the greater miracle.
“How do we get to the top?” Gioia asked.
“Over there, I think. That doorway.”
The spiraling donkey-ramps ended here. The loads of lantern fuel went higher via a dumbwaiter in the central shaft. Visitors continued by way of a cramped staircase, so narrow at its upper end that it was impossible to turn around while climbing. Gioia, tireless, sprinted ahead. He clung to the rail and labored up and up, keeping count of the tiny window slits to ease the boredom of the ascent. The count was nearing a hundred when finally he stumbled into the vestibule of the beacon chamber. A dozen or so visitors were crowded into it. Gioia was at the far side, by the wall that was open to the sea.
It seemed to him he could feel the building swaying in the winds up here. How high were they? Five hundred feet, six hundred, seven? The beacon chamber was tall and narrow, divided by a catwalk into upper and lower sections. Down below, relays of temporaries carried wood from the dumbwaiter and tossed it on the blazing fire. He felt its intense heat from where he stood, at the rim of the platform on which the giant mirror of polished metal was hung. Tongues of flame leaped upward and danced before the mirror, which hurled its dazzling beam far out to sea. Smoke rose through a vent. At the very top was a colossal statue of Poseidon, austere, ferocious, looming above the lantern.
Gioia sidled along the catwalk until she was at his side. “The guide was talking before you came,” she said, pointing. “Do you see that place over there, under the mirror? Someone standing there and looking into the mirror gets a view of ships at sea that can’t be seen from here by the naked eye. The mirror magnifies things.”
“Do you believe that?”
She nodded toward the guide. “It said so. And it also told us that if you look in a certain way, you can see right across the water into the city of Constantinople.”
She is like a child, he thought. They all are. He said, “You told me yourself this very morning that it isn’t possible to see that far. Besides, Constantinople doesn’t exist right now.”
“It will,” she replied. “You said that to me, this very morning. And when it does, it’ll be reflected in the Lighthouse mirror. That’s the truth. I’m absolutely certain of it.” She swung about abruptly toward the entrance of the beacon chamber. “Oh, look, Charles! Here come Nissandra and Aramayne! And there’s Hawk! There’s Stengard!” Gioia laughed and waved and called out names. “Oh,
