The seventeen men who survived had been higher up in the tower. The other eighty-three, including their horses, had, by some unknown device, been swept out into the harbor.
Dakhil was led to the rocky shore east of the lighthouse and was forced to watch the bodies of those he had betrayed wash up against the stones, forced to stare at those he had sent to their deaths, their bloated, battered corpses a testament to his impatience.
He looked on, attempting stoicism, even as Barraq’s men set about sawing off his hands at the wrists and his feet at the ankles. Amidst his screams, they cauterized the stumps with flames from an oil-soaked torch and then chained him to the rocks in the water at the base of the lighthouse, facing west, away from Mecca.
At one point during the ensuing days of agony, as the gulls and the ravenous fish came to feast on his flesh, Dakhil recalled the old Greek legend of Prometheus. He had, after all, merely longed to bring light into the world, to present a powerful gift to mankind. Unlike Prometheus, he had failed; but like the Titan, he had nevertheless been ruthlessly punished.
Barraq left him there after retrieving the dead and placing a team of six men at the summit to staff a continually burning pyre. They could not afford to lose any more ships in the treacherous harbor, and their vigilance against Constantinople must not cease. He rode off on the tenth day of Dakhil’s slow death, too soon to see the lone boat steal across the harbor through the moonless night.
A man in a gray cloak stepped out onto the embankment and calmly traversed the rocks until he reached the dying man. “It seems,” he said after a moment of contemplation, “your father chose poorly.”
Dakhil moaned. His chewed-out eye sockets, above the ragged flesh and protruding cheekbones, turned toward the sound. His lungs choked on seawater and congealed blood. “No…”
“We are Keepers,” said the stranger. “ Keepers. A sacred trust we have held for centuries. I cannot forgive what you have done.”
“Believed… it was time,” Dakhil muttered as the water crashed over his emaciated body and the cloaked form bent over him.
“It is not for us to decide the time. Only to keep the secret until the world is ready.” The words, spoken deeply, powerfully, came from within the folds of his hood. “In the meantime, the Pharos protects itself. The Pharos has always protected itself.”
Dakhil moaned.
The cloaked stranger moved in closer. “While I cannot forgive, I can be merciful.”
A thin blade cut through Dakhil’s throat with almost no resistance and produced very little blood. A soft gasp wheezed into the surf.
The man stood up. He bowed his head toward the flickering beacon high above in a final sign of respect and a renewed commitment to its protection. Then, with a heavy sigh, he made his way back into his boat and sailed into the shadows.

Whoever wants to conquer Egypt has to conquer Alexandria, and whoever wants to conquer Alexandria has to conquer the Harbor.

Alexandria-December
Sixty feet under the harbor’s churning waves, his blue fins kicking just above the reef’s dangerous uppermost protrusions, Professor Caleb Crowe held the grapefruit-sized marble head in his bare hands, letting the colder currents wash off the sediment and muck. He turned the sculpture around, marveling at the late classical Egyptian artistry-the perfect symmetry, the deep-set, thoughtful eyes.
Isis.
The headdress and the Sothis star on her forehead placed this artifact in the Ptolemaic Dynasty-just about the right age. He reached for the camera hanging from his neck, considering how he might use this photo in a series of Ancient History lectures he was currently preparing for the spring semester at Columbia.
In the shadowy depths, the reefs and amphorae intermingled with the huge rocks, immense pillars and chunks of masonry thrust between the long-forgotten shipwrecks. Caleb’s breathing quickened, echoing in his ears even as the Mediterranean’s pressure squeezed his head in its grip. The current tugged him sideways into a massive block of moss-coated basalt.
He let go of the camera and reached out to steady himself. And as Isis looked on, the bare skin on his fingers touched the ancient slab — and something like an electric jolt ripped through his nervous system, starting at the base of his spine and spearing out in all directions. The water shimmered, the sea bottom shuddered, and a red-hot pain tore open the doors to his mind, barged inside and exploded in a blast of golden light like a swarm of maddened yellow jackets on fire, careening off the insides of his skull.
Caleb hadn’t had a clairvoyant vision in more than four years, and to have it strike now, of all times, at the bottom of Alexandria’s harbor, with his air running out and his dive partner wandering off on his own somewhere beyond the dim shadows, was about as dangerous as it was startling. The vision ripped through him like a teasing jolt of pleasure, then just as quickly left him alone again in the cold water, with Isis’s eyes looking upon him with pity.
There was a brief moment of confusion, then it returned with a vengeance. He doubled over, hyperventilating, burning through his oxygen, seeing…
His mind reeled and his stomach twisted. An armada of bubbles surrounded his head like ravenous fish, nipping at his skin, shouting out alarms. But his eyes, wide open, no longer perceived what lay before him, for they strode with his mind…
… to the tower… the lighthouse… the Pharos… there it is, rising before him, a three-stage construction, almost four hundred feet high, tapering to a glorious spire that seems to challenge the simmering Egyptian sun itself. The tower’s outer casing glitters on the western side, reflecting the sun with the light of a thousand stars, and all along its ascent hang statues of divinities and mythical guardians, peering down from their lofty perches.
He tears his eyes away and blinks, bringing into focus the man standing on the steps, welcoming him. A man he instinctively knows as the architect of the Pharos: Sostratus of Cnidos.
“Welcome, Demetrius,” he says. “Come, I have much to show you.”
Seeing through Demetrius’s eyes, Caleb speaks as if following a well-rehearsed script. His voice cracks and the words spill like gravel off his parched tongue. “Sostratus, engineering wonder this may be, yet it has the imposing grandeur, aura and beauty of the divine. My friend, this lighthouse will be adored for ages.”
Sostratus turns and looks up at his handiwork. “I hope you are right, and humbly, I trust in the gods that I have built it well enough to last.” He helps Demetrius up the final steps into the courtyard, where doves and sparrows coo in transplanted palm trees and fountains pour out fresh reservoir water at each of the cardinal points.
“And it is not yet done.” Sostratus raises his hand to the distant, dwindling spire atop the converging stages; past the mammoth two-hundred-foot rectangular lower section, pierced with three hundred windows; beyond the octagonal second stage, rising a hundred feet more, to the last part ascending the final hundred feet.
