Tree and Moonlight are placed on the second team. The order is given and the animals are goaded. Ropes groan, yokes squeak, and the oxen march slowly in place, churning the soil to a sea of mud.

“Pull, boys, all your strength,” Omeir calls. The entire team drives their hooves deeper into the clay. The teamsters add a sixth chain, a sixth rope, a sixth team of ten. By now it is nearly dusk and the bullocks stand heaving in the shafts. With a sharp cry, the air fills with “Ho!” and “Hai!” and sixty oxen begin to pull.

The animals lean forward, are hauled back as one by the incredible weight, then lean forward again, earning one step, another, drivers yelling, switching their animals, the bullocks bellowing in fear and confusion.

The immense load is a whale swimming out of the earth. They haul it maybe fifty yards before the order is given to stop. Vapor gushes from the bullocks’ nostrils and Omeir checks Tree’s and Moonlight’s yoke and shoes, and already scrapers and polishers are scrambling over the apparatus where it smokes in the cold twilight, the bronze still warm.

Maher crosses his skinny arms. He says, to no one in particular, “They will need to invent an entirely different kind of cart.”

To pull the apparatus the mile from the foundry to the sultan’s testing ground takes three days. Three times the spokes on the wagon’s wheels splinter and the rims fall out of round; wheelwrights rush around it, working day and night; the load is so heavy that every hour it sits on the cart it drives the wheels another inch into the ground.

In a field within sight of the sultan’s new palace, a crane is used to hoist the huge hooped tube of the apparatus onto a wooden platform. An impromptu bazaar springs up: traders sell bulgur and butter, roasted thrushes and smoked ducks, sacks of dates and silver necklaces and wool bonnets. Fox fur is everywhere, as though every fox in the world has been slain and turned into a cape, and some men wear gowns of snow-white ermine, and others wear mantles of fine felt upon which raindrops bead up and skitter off, and Omeir cannot take his eyes off any of them.
