“When they began the tower, the architects knew that far more wood would be needed to fuel the kilns than could be found on the plain, so they had a forest planted. There are crews who provide water and plant one new tree for each that is cut.”
Hillalum was astonished. “And that provides all the wood needed?”
“Most of it. Many other forests in the north have been cut as well, and their wood brought down the river.” He inspected the wheels of the cart, uncorked a leather bottle he carried, and poured a little oil between the wheel and axle.
Nanni walked over to them, staring at the streets of Babylon laid out before them. “I've never before been this high, that I can look down upon a city.”
“Nor have I,” said Hillalum, but Lugatum simply laughed. “Come along. All of the carts are ready.”
Soon all the men were paired up and matched with a cart. The men stood between the carts' two pull rods, which had rope loops for pulling. The carts pulled by the miners were mixed in with those of the regular pullers, to ensure that they would keep the proper pace. Lugatum and another puller had the cart right behind that of Hillalum and tower of Nanni.
“Remember,” said Lugatum, “stay about ten cubits behind the cart in front of you. The man on the right does all the pulling when you turn corners, and you'll switch every hour.”
Pullers were beginning to lead their carts up the ramp. Hillalum and Nanni bent down and slung the ropes of their cart over their opposite shoulders. They stood up together, raising the front end of the cart off the pavement.
“Now PULL,” called Lugatum.
They leaned forward against the ropes, and the cart began rolling. Once it was moving, pulling seemed to be easy enough, and they wound their way around the platform. Then they reached the ramp, and they again had to lean deeply. “This is a light wagon?” muttered Hillalum.
The ramp was wide enough for a single man to walk beside a cart if he had to pass. The surface was paved with brick, with two grooves worn deep by centuries of wheels. Above their heads, the ceiling rose in a corbeled vault, with the wide, square bricks arranged in overlapping layers until they met in the middle. The pillars on the right were broad enough to make the ramp seem a bit like a tunnel. If one didn't look off to the side, there was little sense of being on a tower.
“Do you sing when you mine?” asked Lugatum.
“When the stone is soft.”
“Sing one of your mining songs, then.”
The call went down to the other miners, and before long the entire crew was singing.
As the shadows shortened, they ascended higher and higher. With only clear air surrounding them, and much shade from the sun, it was much cooler than in the narrow alleys of a city at ground level, where the heat at midday could kill lizards as they scurried across the street. Looking out to the side, the miners could see the dark Euphrates, and the green fields stretching out for leagues, crossed by canals that glinted in the sunlight. The city of Babylon was an intricate pattern of close-set streets and buildings, dazzling with gypsum whitewash; less and less of it was visible as it seemingly drew nearer the base of the tower.
Hillalum was again pulling on the right-hand rope, nearer the edge, when he heard some shouting from the upward ramp one level below. He thought of stopping and looking down the side, but he didn't wish to interrupt their pace, and he wouldn't be able to see the lower ramp clearly anyway. “What's happening down there?” he called to Lugatum behind him.
“One of your fellow miners fears the height. There is occasionally such a man among those who climb for the first time. Such a man embraces the floor and cannot ascend further. Few feel it so soon, though.”
Hillalum understood. “We know of a similar fear, among those who would be miners. Some men cannot bear to enter the mines, for fear that they will be buried.”
“Really?” called Lugatum. “I had not heard of that. How do you feel yourself about the height?”
“I feel nothing.” But he glanced at Nanni, and they both knew the truth.
“You feel nervousness in your palms, don't you?” whispered Nanni.
Hillalum rubbed his hands on the coarse fibers of the rope and nodded.
“I felt it, too, earlier when I was closer to the edge.”
“Perhaps we should go hooded, like the ox and the goat,” muttered Hillalum jokingly.
“Do you think we, too, will fear the height, when we climb further?”
Hillalum considered. That one of their comrades should feel the fear so soon did not bode well. He shook it off; thousands climbed with no fear, and it would be foolish to let one miner's fear infect them all. “We are merely unaccustomed. We will have months to grow used to the height. By the time we reach the top of the tower, we will wish it were taller.”
“No,” said Nanni. “I don't think I'll wish to pull this any further.”
They both laughed.
In the evening they ate a meal of barley and onions and lentils, and slept inside narrow corridors that penetrated into the body of the tower. When they woke the next morning, the miners were scarcely able to walk, so sore were their legs. The pullers laughed, and gave them salve to rub into their muscles, and redistributed the load on the carts to reduce the miners' burden.
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 them. 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 behind 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?”
Hillalum said nothing. For the first time, he knew night for what it was: the shadow of the earth itself, cast against the sky.
