At the rear of the room, on the right-hand side, the miners burned out a narrow upward-sloping corridor, and in the floor in front of the chamber entrance they dug a downward-sloping channel into the floor for a cubit. Thus there was a smooth continuous ramp that cut across the floor immediately in front of the entrance and ended just to its left.
On this ramp the Egyptians loaded the block of granite. They dragged and pushed it up into the side corridor, where it just barely fit, and propped it in place with a stack of flat mud bricks braced against the bottom of the left wall, like a pillar lying on the ramp.
With the sliding stone to hold back the waters, it was safe for the miners to continue tunneling. If they broke into a reservoir and the waters of heaven began pouring down into the tunnel, they would break the bricks one by one, and the stone would slide down until it rested in the recess in the floor, utterly blocking the doorway. If the waters flooded in with such force that they washed men out of the tunnels, the mud bricks would gradually dissolve, and again the stone would slide down. The waters would be retained, and the miners could then begin a new tunnel in another direction, to avoid the reservoir.
The miners again used fire setting to continue the tunnel, beginning at the far end of the room. To aid the circulation of air within the vault, oxhides were stretched on tall frames of wood and placed obliquely on either side of the tunnel entrance at the top of the tower. Thus the steady wind that blew underneath the vault of heaven was guided upward into the tunnel; it kept the fire blazing and cleared the air after the fire was extinguished, so that the miners could dig without breathing smoke.
The Egyptians did not stop working once the sliding stone was in place. While the miners swung their picks at the tunnel's end, the Egyptians labored at the task of cutting a stair into the solid stone, to replace the wooden steps. This they did with the wooden wedges, and the blocks they removed from the sloping floor left steps in their place.
Thus the miners worked, extending the tunnel on and on. The tunnel always ascended, though it reversed direction regularly like a thread in a giant stitch, so that its general path was straight up. They built other sliding-door rooms so that only the uppermost segment of the tunnel would be flooded if they penetrated a reservoir. They cut channels in the vault's surface from which they hung walkways and platforms; starting from these platforms, well away from the tower, they dug side tunnels, which joined the main tunnel deep inside. The wind was guided through these to provide ventilation, clearing the smoke from deep inside the tunnel.
For years the labor continued. The pulling crews no longer hauled bricks but wood and water for the fire setting. People came to inhabit those tunnels just inside the vault's surface, and on hanging platforms they grew downward-bending vegetables. The miners lived there at the border of heaven; some married and raised children. Few ever set foot on the earth again.
With a wet cloth wrapped around his face, Hillalum climbed down from wooden steps onto stone, having just fed some more wood to the bonfire at the tunnel's end. The fire would continue for many hours, and he would wait in the lower tunnels, where the wind was not thick with smoke.
Then there was a distant sound of shattering, the sound of a mountain of stone being split through, and then a steadily growing roar. A torrent of water came rushing down the tunnel.
For a moment, Hillalum was frozen in horror. The water, shockingly cold, slammed into his legs, knocking him down. He rose to his feet, gasping for breath, leaning against the current, clutching at the steps.
They had hit a reservoir.
He had to descend below the highest sliding door, before it was closed. His legs wished to leap down the steps, but he knew he couldn't remain on his feet if he did, and being swept down by the raging current would likely batter him to death. Going as fast as he dared, he took the steps one by one.
He slipped several times, sliding down as many as a dozen steps each time; the stone steps scraped against his back, but he felt no pain. All the while he was certain the tunnel would collapse and crush him, or else the entire vault would split open, and the sky would gape beneath his feet, and he would fall down to Earth amidst the heavenly rain. Yahweh's punishment had come, a second Deluge.
How much further until he reached the sliding stone? The tunnel seemed to stretch on and on, and the waters were pouring down even faster now. He was virtually running down the steps.
Stumbling, he splashed into shallow water. He had run down past the end of the stairs and fallen into the room of the sliding stone, and there was water higher than his knees. He stood up and saw Damqiya and Ahuni, two fellow miners, just noticing him. They stood in front of the stone, which already blocked the exit.
“No!” he cried.
“They closed it!” screamed Damqiya. “They did not wait!”
“Are there others coming?” shouted Ahuni, without hope. “We may be able to move the block.”
“There are no others,” answered Hillalum. “Can they push it from the other side?”
“They cannot hear us.” Ahuni pounded the granite with a hammer, making not a sound against the din of the rushing water.
Hillalum looked around the tiny room, only now noticing that an Egyptian floated facedown in the water.
“He died falling down the stairs,” yelled Damqiya.
“Is there nothing we can do?”
Ahuni looked upward. “Yahweh, spare us.”
The three of them stood in the rising water, praying desperately, but Hillalum knew it was in vain: Yahweh had not asked men to build the tower or to pierce the vault; the decision belonged to men alone, and they would die in this endeavor just as they did in any of their earthbound tasks. Their righteousness could not save them from the consequences of their deeds.
The water reached their chests. “Let us ascend,” shouted Hillalum.
They climbed the tunnel laboriously, against the onrush, as the water rose behind their heels. The few torches illuminating the tunnel had been extinguished, so they ascended in the dark, murmuring prayers that they couldn't hear. The wooden steps at the top of the tunnel had dislodged from their place and were jammed farther down in the tunnel. They climbed past them until they reached the smooth stone slope, and there they waited for the water to carry them higher.
They waited without words, their prayers exhausted. Hillalum imagined that he stood in the black gullet of Yahweh, as the Mighty One drank deep of the waters of heaven, ready to swallow the sinners.
The water rose and bore them up, until Hillalum could reach up with his hands and touch the ceiling. The giant fissure from which the waters gushed forth was right next to him. Only a tiny pocket of air remained. Hillalum shouted, “When this chamber is filled, we can swim heavenward.”
He could not tell if they heard him. He gulped his last breath as the water reached the ceiling, and swam up into the fissure. He would die closer to heaven than any man ever had before.
The fissure extended for many cubits. As soon as Hillalum passed through, the stone stratum slipped from his fingers, and his flailing limbs touched nothing. For a moment he felt a current carrying him, but then he was no longer sure. With only blackness around him, he once again felt that horrible vertigo that he had experienced when first approaching the vault: He could not distinguish any directions, not even up or down. He pushed and kicked against the water but did not know if he moved.
Helpless, he was perhaps floating in still water, perhaps swept furiously by a current; all he felt was numbing cold. Never did he see any light. Was there no surface to this reservoir that he might rise to?
