By now, looking down the side turned Hillalum's knees to water. A wind blew steadily at this height, and he anticipated that it would grow stronger as they climbed. He wondered if anyone had ever been blown off the tower in a moment of carelessness. And the fall; a man would have time to say a prayer before he hit the ground. Hillalum shuddered at the thought.
Aside from the soreness in the miners’ legs, the second day was similar to the first. They were able to see much farther now, and the breadth of land visible was stunning; the deserts beyond the fields were visible, and caravans appeared to be little more than lines of insects. No other miner feared the height so greatly that he couldn't continue, and their ascent proceeded all day without incident.
On the third day, the miners’ legs had not improved, and Hillalum felt like a crippled old man. Only on the fourth day did their legs feel better, and they were pulling their original loads again. Their climb continued until the evening, when they met the second crew of pullers leading empty carts rapidly along the downward ramp. The upward and downward ramps wound around each other without touching, but they were joined by the corridors through the tower's body. When the crews had intertwined thoroughly on the two ramps, they crossed over to exchange carts.
The miners were introduced to the pullers of the second crew, and they all talked and ate together that night. The next morning, the first crew readied the empty carts for their return to Babylon, and Lugatum bid farewell to Hillalum and Nanni.
"Take care of your cart. It has climbed the entire height of the tower, more times than any man."
"Do you envy the cart, too?” asked Nanni.
"No, because every time it reaches the top, it must come all the way back down. I could not bear to do that."
* * * *
When the second crew stopped at the end of the day, the puller of the cart behind Hillalum and Nanni came over to show them something. His name was Kudda.
“You have never seen the sun set at this height. Come, look.”
The puller went to the edge and sat down, his legs hanging over the side. He saw that they hesitated. “Come. You can lie down and peer over the edge, if you like.” Hillalum did not wish to seem like a fearful child, but he could not bring himself to sit at a cliff face that stretched for thousands of cubits below his feet. He lay down on his belly, with only his head at the edge. Nanni joined him.
"When the sun is about to set, look down the side of the tower.” Hillalum glanced downward, and then quickly looked to the horizon.
"What is different about the way the sun sets here?"
"Consider, when the sun sinks behinds the peaks of the mountains to the west, it grows dark down on the plain of Shinar. Yet here, we are higher than the mountaintops, so we can still see the sun. The sun must descend further for us to see night."
Hillalum's jaw dropped as he understood. “The shadows of the mountains mark the beginning of night. Night falls on the earth before it does here."
Kudda nodded. “You can see night travel up the tower, from the ground up to the sky. It moves quickly, but you should be able to see it."
He watched the red globe of the sun for a minute, and then looked down and pointed. “Now!"
Hillalum and Nanni looked down. At the base of the immense pillar, tiny Babylon was in shadow. Then the darkness climbed the tower, like a canopy unfurling upward. It moved slowly enough that Hillalum felt he could count the moments passing, but then it grew faster as it approached, until it raced past them faster than he could blink, and they were in twilight.
Hillalum rolled over and looked up, in time to see darkness rapidly ascend the rest of the tower. Gradually, the sky grew dimmer as the sun sank beneath the edge of the world, far away.
"Quite a sight, is it not?” said Kudda.
Hillalum said nothing. For the first time, he knew night for what it was: the shadow of the earth itself, cast against the sky.
* * * *
After climbing for two more days, Hillalum had grown more accustomed to the height. Though they were the better part of a league straight up, he could bear to stand at the edge of the ramp and look down the tower. He held on to one of the pillars at the edge, and cautiously leaned out to look upward. He noticed that the tower no longer looked like a smooth pillar.
He asked Kudda, “The tower seems to widen further up. How can that be?"
"Look more closely. There are wooden balconies reaching out from the sides. They are made of cypress, and suspended by ropes of flax."
Hillalum squinted. “Balconies? What are they for?"
"They have soil spread on them, so people may grow vegetables. At this height water is scarce, so onions are most commonly grown. Higher up, where there is more rain, you'll see beans."
Nanni asked, “How can there be rain above that does not just fall here?"
Kudda was surprised at him. “It dries in the air as it falls, of course."
"Oh, of course.” Nanni shrugged.
By the end of the next day they reached the level of the balconies. They were flat platforms, dense with onions, supported by heavy ropes from the tower wall above, just below the next tier of balconies. On each level the interior of the tower had several narrow rooms inside, in which the families of the pullers lived. Women could be seen sitting in the doorways sewing tunics, or out in the gardens digging up bulbs. Children chased each other up and down the ramps, weaving amidst the pullers’ carts, and running along the edge of the balconies without fear. The tower dwellers could easily pick out the miners, and they all smiled and waved.
When it came time for the evening meal, all the carts were set down and food and other goods were taken off to be used by the people here. The pullers greeted their families, and invited the miners to join them for the evening meal. Hillalum and Nanni ate with the family of Kudda, and they enjoyed a fine meal of dried fish, bread, date wine, and fruit.
Hillalum saw that this section of the tower formed a tiny kind of town, laid out in a line between two streets, the upward and downward ramps. There was a temple, in which the rituals for the festivals were performed; there were magistrates, who settled disputes; there were shops, which were stocked by the caravan. Of course, the town was inseparable from the caravan: neither could exist without the other. And yet any caravan was essentially a journey, a thing that began at one place and ended at another. This town was never intended as a permanent place, it was merely part of a centuries-long journey.
After dinner, he asked Kudda and his family, “Have any of you ever visited Babylon?"
Kudda's wife, Alitum, answered, “No, why would we? It's a long climb, and we have all we need here."
"You have no desire to actually walk on the earth?"
Kudda shrugged. “We live on the road to heaven; all the work that we do is to extend it further. When we leave the tower, we will take the upward ramp, not the downward."
* * * *
As the miners ascended, in the course of time there came the day when the tower appeared to be the same when one looked upward or downward from the ramp's edge. Below, the tower's shaft shrank to nothing long before it seemed to reach the plain below. Likewise, the miners were still far from being able to see the top. All that was visible was a length of the tower. To look up or down was frightening, for the reassurance of continuity was gone; they were no longer part of the ground. The tower might have been a thread suspended in the air, unattached to either earth or to heaven.
There were moments during this section of the climb when Hillalum despaired, feeling displaced and estranged from the world; it was as if the earth had rejected him for his faithlessness, while heaven disdained to accept him. He wished Yahweh would give a sign, to let men know that their venture was approved; otherwise how could they stay in a place that offered so little welcome to the spirit?
The tower dwellers at this altitude felt no unease with their station; they always greeted the miners warmly and wished them luck with their task at the vault. They lived inside the damp
mists of clouds, they saw storms from below and from above, they harvested crops from the air, and they never feared that this was an improper place for men to be. There were no divine assurances or encouragements to be had, but the people never knew a moment's doubt.
With the passage of the weeks, the sun and moon peaked lower and lower in their daily journeys. The moon flooded the south side of the tower with its silver radiance, glowing like the eye of Yahweh peering at them. Before long, they were at precisely the same level as the moon when it passed; they had reached the height of the first of the celestial bodies. They squinted at the moon's pitted face, marveled at its stately motion that scorned any support.
Then they approached the sun. It was the summer season, when the sun appears nearly overhead from Babylon, making it pass close by the tower at this height. No families lived in this section of the tower, nor were there any balconies, since the heat was enough to roast barley. The mortar between the tower's bricks was no longer bitumen, which would have softened and flowed, but clay, which had been virtually baked by the heat. As protection against the day temperatures, the pillars had been widened until they formed a nearly continuous wall, enclosing the ramp into a tunnel with only narrow slots admitting the whistling wind and blades of golden light.
The crews of pullers had been spaced regularly up to this point, but here an adjustment was necessary. They started out earlier and earlier each morning, to gain more darkness for when they pulled. When they were at the level of the sun, they traveled entirely at night. During the day, they tried to sleep, naked and sweating in the hot breeze. The miners worried that if they did manage to sleep, they would be baked to death before they awoke. But the pullers had made the journey many times, and never lost a man, and eventually they passed above the sun's level, where things were as they had been below.
Now the light of day shone upward, which seemed unnatural to the utmost. The balconies had planks removed from them so that the sunlight could shine through, with soil on the walkways that remained; the plants grew sideways and downward, bending over to catch the sun's rays.
Then they drew near the level of the stars, small fiery spheres spread on all sides. Hillalum had expected them to be spread more thickly, but even with the tiny stars invisible from the ground, they seemed to be thinly scattered. They were not all set at the same height, but instead occupied the next few leagues above. It was difficult to tell how far they were, since there was no indication of their size, but occasionally one would make a close approach, evidencing its astonishing speed. Hillalum realized that all the objects in the sky hurtled by with similar speed, in order to travel the world from edge to edge in a day's time.
During the day, the sky was a much paler blue than it appeared from the earth, a sign they were nearing the vault. When studying the sky, Hillalum was startled to see that there were stars visible during the day. They couldn't be seen from the earth amidst the glare of the sun, but from this altitude they were quite distinct.
One day Nanni came to him hurriedly and said, “A star has hit the tower!"
"What!” Hillalum looked around, panicked, feeling like he had been struck by a blow.
"No, not now. It was long ago, more than a century. One of the tower dwellers is telling the story; his grandfather was there."
They went inside the corridors, and saw several miners seated around a wizened old man. “—lodged itself in the bricks about half a league above here. You can still see the scar it left; it's like a giant pockmark."
"What happened to the star?"
"It burned and sizzled, and was too bright to look upon. Men considered prying it out, so that it might resume its course, but it was too hot to approach closely, and they dared not quench it. After weeks it cooled into a knotted mass of black heaven-metal, as large as a man could wrap his arms around."
"So large?” said Nanni, his voice full of awe. When stars fell to the earth of their own accord, small lumps of heaven-metal were sometimes found, tougher than the finest bronze. The metal could not be melted for casting, so it was worked by hammering when heated red; amulets were made from it.
"Indeed, no one had ever heard of a mass of this size found on the earth. Can you imagine the tools that could be made from it!"
"You did not try to hammer it into tools, did you?” asked Hillalum, horrified.
"Oh no. Men were frightened to touch it. Everyone descended from the tower, waiting for retribution from Yahweh for disturbing the workings of Creation. They waited for months, but no sign came. Eventually they returned, and pried out the star. It sits in a temple in the city below."
There was silence. Then one of the miners said, “I have never heard of this in the stories of the tower."
"It was a transgression, something not spoken of."
* * * *
As they climbed higher up the tower, the sky grew lighter in color, until one morning Hillalum awoke and stood at the edge and yelled from shock: what had before seemed a pale sky now appeared to be a white ceiling stretched far above their heads. They were close enough now to perceive the vault of heaven, to see it as a solid carapace enclosing all the sky. All of the miners spoke in hushed tones, staring up like idiots, while the tower dwellers laughed at them.
As they continued to climb, they were startled at how near they actually were. The blankness of the vault's face had deceived them, making it undetectable until it appeared, abruptly, seeming just above their heads. Now instead of climbing into the sky, they climbed up to a featureless plain that stretched endlessly in all directions.
All of Hillalum's senses were disoriented by the sight of it. Sometimes when he looked at the vault, he felt as if the world had flipped around somehow, and if he lost his footing he would fall upward to meet it. When the vault did appear to rest above his head, it had an oppressive weight. The vault was a stratum as heavy as all the world, yet utterly without support, and he feared what he never had in the mines: that the ceiling would collapse upon him.
Too, there were moments when it appeared as if the vault were a vertical cliff face of unimaginable height rising before him, and the dim earth behind him was another like it, and the tower was a cable stretched taut between the two. Or worst of all, for an instant it seemed that there was no up and no down, and his body did not know which way it was drawn. It was like fearing the height, but much worse. Often he would wake from an unrestful sleep, to find himself sweating and his fingers cramped, trying to clutch the brick floor.
Nanni and many of the other miners were bleary-eyed too, though no one spoke of what disturbed their sleep. Their ascent grew slower, instead of faster as their foreman Beli had expected; the sight of the vault inspired unease rather than eagerness. The regular pullers became impatient with them. Hillalum wondered what sort of people were forged by living under such conditions; how did they escape madness? Did they grow accustomed to this? Would the children born under a solid sky scream if they saw the ground beneath their feet?
Perhaps men were not meant to live in such a place. If their own natures restrained them from approaching heaven too closely, then men should remain on the earth.
When they reached the summit of the tower, the disorientation faded, or perhaps they had grown immune. Here, standing upon the square platform of the top, the miners gazed upon the most awesome scene ever glimpsed by men: far below them lay a tapestry of soil and sea, veiled by mist, rolling out in all directions to the limit of the eye. Just above them hung the roof of the world itself, the absolute upper demarcation of the sky, guaranteeing their vantage point as the highest possible. Here was as much of Creation as could be apprehended at once.
The priests led a prayer to Yahweh; they gave thanks that they were permitted to see so much, and begged forgiveness for their desire to see more.
* * * *
And at the top, the bricks were laid. One could catch the rich, raw smell of tar, rising out of the heated cauldrons in which the lumps of bitumen were melted. It was the most earthy odor the m
iners had smelled in four months, and their nostrils were desperate to catch a whiff before it was whipped away by the wind. Here at the summit, where the ooze that had once seeped from the earth's cracks now grew solid to hold bricks in place, the earth was growing a limb into the sky.
Here worked the bricklayers, the men smeared with bitumen who mixed the mortar and deftly set the heavy bricks with absolute precision. More than anyone else, these men could not permit themselves to experience dizziness when they saw the vault, for the tower could not vary a finger's width from the vertical. They were nearing the end of their task, finally, and after four months of climbing, the miners were ready to begin theirs.
The Egyptians arrived shortly afterwards. They were dark of skin and slight of build, and had sparsely bearded chins. They had pulled carts filled with dolerite hammers, and bronze tools, and wooden wedges. Their foreman was named Senmut, and he conferred with Beli, the Elamites’ foreman, on how they would penetrate the vault. The Egyptians built a forge with what they had brought, as did the Elamites, for recasting the bronze tools that would be blunted during the mining.
The vault itself remained just above a man's outstretched fingertips; it felt smooth and cool when one leapt up to touch it. It seemed to be made of fine-grained white granite, unmarred and utterly featureless. And therein lay the problem.
Long ago, Yahweh had released the Deluge, unleashing waters from both below and above; the waters of the Abyss had burst forth from the springs of the earth, and the waters of heaven had poured through the sluice gates in the vault. Now men saw the vault closely, but there were no sluice gates discernible. They squinted at the surface in all directions, but no openings, no windows, no seams interrupted the granite plain.
It seemed that their tower met the vault at a point between any reservoirs, which was fortunate indeed. If a sluice gate had been visible, they would have had to risk breaking it open and emptying the reservoir. That would mean rain for Shinar, out of season and heavier than the winter rains; it would cause flooding along the Euphrates. The rain would most likely end when the reservoir was emptied, but there was always the possibility that Yahweh would punish them and continue the rain until the tower fell and Babylon was dissolved into mud.
