At Rashwan's quarry, Egyptian laborers await the call
to have another go at the ropes.

Pulling Together
by Peter Tyson
March 14, 1999
It might have been the 20th century B.C. in our small corner
of
Hamada Rashwan's
Aswan quarry today. Eight or ten quarrymen squatted atop a
long sliver of granite, chiseling it into an obelisk. Others
kindled small fires atop other slabs of granite before trying
to break off slices loosened by the heat. Wood smoke hung in
the air, as did the tap-tap-tap of dolerite balls striking yet
other blocks of granite, whose dimpled surface workers sought
to bring into a semblance of smoothness.
Most noticeably, a crowd of 50 Egyptian laborers, encouraging
one another with raucous cries of mutual support, yanked on
ropes attached to a truck-sized block of stone. Weighing
perhaps 25 tons, the block rested on a wooden sledge, which
the workers were trying to haul along a patch of ground.
Earlier, they had firmed up the ground with embedded wooden
sleepers laid down crosswise like railroad ties, and had
lubricated the sleepers with greasy smears of tallow. The rock
had not yet budged, but we were hopeful.
Why the 20th-century B.C.? Well, we know the ancient Egyptians
chipped granite, used dolerite pounders, and built embrittling
fires to help shape granite. And we know they designed wooden
sledges to transport heavy statues.

In fact, our little scene looked strikingly similar to one
depicted in a relief from the 20th-century B.C. The 12th
Dynasty scene shows a gigantic statue of Djehutihotep lashed
to a wooden sledge, which 172 laborers in four rows pull using
ropes tied to the sledge's leading edge. One man leans out
over the statue's feet, pouring a liquid under the sledge to
lubricate the runners. Another man, apparently calling out
orders or encouragement to the pullers, perches on the knees
of the statue, which scholars estimated would have weighed 57
tons.
And why were we doing all this? Because our obelisk-raising
team had finally assembled itself in its entirety here in
Aswan and had begun to undertake various tests of how the
ancients quarried, worked, moved, shipped, and raised
obelisks. The biggest test of the day, of course, was the
sledge-hauling.
We don't know if we had the particulars of the ancient
technology exactly right—we used tallow, they might have
used water or oil; our ropes were of sisal, theirs perhaps of
halfa grass; and so on—but we came as close as we could.
The question now was, would it work?

Several of our resident experts felt that as few as 50 men
could haul the sledge along the designated path once they'd
succeeded in releasing it from the ground's grip. (The sledge
had had 24 hours to settle down.) So we tried 50. No go. We
tried 100. Still no go. In an atmosphere of rising tension, as
each expert tried to advance his or her theory on how best to
proceed,
Roger Hopkins
convinced the team to add levers. Workers soon had several
wooden levers as big as telephone poles wedged beneath the
block, and as they levered and the pullers pulled, the sledge
came alive.
Actually, it moved only a few inches, and then a
rope—perhaps weakened by rubbing against the
rock—parted, flinging chief foreman
Abdel Aleem and
a bunch of others onto their backs.
A lunch break was called. It was now about 3 p.m., and we had
managed to move the sledge only about two feet.
Mark Lehner
told me that, to symbolize the word for "marvel" or "wonder,"
the Egyptians used the hieroglyph for sledge, indicating how
well this device worked for them. Would it do so for us?
At lunch, each of our experts had a different theory as to why
it had barely budged. "We weren't strong enough,"
Owain Roberts
said with a chuckle, adding that a few more pullers should do
it. Hopkins, not surprisingly, felt we needed more levers and
better levering points. For
Mark Whitby,
the problem lay in communication. No one seemed to be fully in
charge, he said, which proved especially troublesome with so
many nationalities involved. I couldn't find Aleem, but
earlier he had said that 50 men alone could move it—if
it rested on rollers. Finally, Mark Lehner said he thought the
pullers had simply not yet achieved the required rhythm, which
he said could conceivably take hours.

By 4:30, with no consensus but to continue doing what we'd
been doing, we went at it again. Like the presumed foreman in
the Djehutihotep relief, Hopkins hopped atop the block and,
through yells in Arabic and deliberately grandiose
gesticulations, managed to get the men into Lehner's hoped-for
rhythm. And it seemed to work. With each Arabic equivalent of
"Heave ho!" the sledge moved forward a few inches.
But with the sun starting its descent to the dust-colored
horizon, another rope separated, then another. Each time,
Roberts retied them with the help of some of the quarrymen.
Yet the day was quickly dying.
Finally, Hopkins called out:
"This is the last time!"
Then, from on high, he turned to 200-plus leverers and
pullers, and yelled at the top of his lungs,
"ALLAH AKBAR!! (GOD IS GREAT!)"
The sledge jumped and, for the first time, kept on going. One
foot, two feet, five feet. Only after about ten feet did it
finally grind to a halt.

Ten feet. All told, in a day's work, maybe 20 feet. Had we
done justice to Djehutihotep? Or did our attempt to recreate
it in a fashion pale in comparison?
It may not sound like a great distance—and I did
overhear one or two experts express private disappointment and
surprise that we had not achieved greater—but you
couldn't convince the workers of that. As soon as the rock
stopped, a cheer went up that I'd bet you could hear right
across to the Aga Khan Mausoleum on the other side of the
Nile, and several of the men lofted a beaming Hopkins high
into the air.
