1In the days when Uruk was already old, there was a third river, far to the east, past the salt desert and the sea. It was wider than the others and wilder. On its banks stood cities whose names are lost.
2They were not like the cities of the west. They had no mountain for a dead king and no great house for a living one. Their streets ran straight. Every house had a place for washing, and the dirty water ran away under the street in drains of brick. And every brick in every city, a month's walk apart, was made to one shape: as thick as one, as wide as two, as long as four.
3They had a thing they loved more than gold, and it was the true weight. Their weights were small cubes of banded stone, polished like water. Each was double the one before it: one, two, four, eight, sixteen, thirty-two, sixty-four. A cube from the city in the north would balance a cube from the city by the sea, to the breadth of a mustard seed. No one alive could say who had first made them agree. They only kept them so.
4In the greatest of those cities lived a bead-maker named Daman and his daughter Ila.
5Daman made the long red beads that the western kings would pay any price for. The stone was carnelian, and the bead was as long as a finger. To drill the hole through it took him the better part of a week, turning a stone point with a bow, drop of water by drop of water. He had lost his wife to the river fever when Ila was small. He had the child and the beads, and he was careful with both.
6Ila was thirteen. She could not drill. Her hands were too quick for it. But she could weigh. She could take a stone in her palm and say "eleven," and the balance would say eleven.
7That year Daman had forty long beads, the work of most of a year. A ship was going west, to the land of the black-headed people, where a new king named Sargon had made himself master of all the cities and called for the goods of the whole world to come to his quay.
8"I cannot leave you," Daman said. "And I cannot stay." So he took her.
9They went down the river with the current, twelve days, to the sea. There the ship was waiting: planks sewn with cord, one mast, a master named Kor who had made the crossing nine times and had lost two fingers to it. Daman paid for their places with three beads. He kept the rest in a belt next to his skin.
10On the water, the father began to teach the daughter. There was nothing else to do, and he was a man who could not sit idle.
11He taught her the stars the steersman used. He showed her the one that does not move, and how the others wheel about it. He taught her the count of days between each watering place, tying knots in a cord. He taught her forty words of the black-headed people's tongue: silver, wool, barley, how much, too much, you are cheating me. And he took out his little bag of cube weights and taught her what she thought she knew already.
12"You can feel a weight," he said. "Good. But the man across the scale cannot feel what you feel. He must be able to see it. So you never say, trust my hand. You say, here is the stone, here is its brother, put them in the pans yourself. A true weight is a thing two strangers can stand on. That is all it is. That is everything it is."
13She listened with half an ear. She was thirteen, and there were dolphins.
14They watered at the copper coast, where the mountains come down red to the sea. They were five days past it when the storm found them.
15It came out of a clear evening, as storms do in that sea, a black wall with lightning walking under it. Kor shouted to get the sail down. The wind got there first. The ship lay over until the sea came in across the side. The great steering oar tore out of the steersman's hands and swung.
16Ila saw it swing. She saw her father step toward the steersman to help him. She saw the oar take him across the chest and throw him down among the bales.
17The storm blew out by morning. The ship was afloat, with half its water gone and its mast sprung. Daman lay under the awning and breathed as if each breath had to be bought. There was something broken inside him that no one could see.
18He lasted eleven days, until the island of sweet water, where springs rise in the sea itself and the dead of that people lie under ten thousand round mounds. He was clear in his mind, and he did not waste the days.
19He made her say the stars again. He made her say the forty words. He made her weigh, with her eyes shut, every cube in the bag. He told her the name of a man of their own country who lived on the quay of the western king and turned one tongue into the other: Shu-ilishu. On the last evening he took off the belt and put it round her waist himself, and he hung his seal about her neck. It was a square of white stone cut with a one-horned bull and five signs.
20"That is my name," he said. "When you press it, I have spoken. Do not press it for a lie."
21"Do not talk as if you are going," said Ila.
22"I am going," said Daman. "I have known it since the oar. Listen. I am not afraid for the beads. I am afraid you will sit down on this island and wait for someone to take you home." He closed his eyes. "I have put everything I know into you these eleven days. It is the only place I had to put it. Do not let it sit."
23He died in the night. They buried him among the mounds of that island, and a man of the place piled the earth for the price of one bead. Ila set a pebble on the top.
24Then Kor came to her. He was not a cruel man. He was a man with a damaged ship and nine mouths to pay. "Child," he said, "here is how it will be. You cannot trade. You have no tongue for it and no beard. Give me the belt. I will sell the beads on the quay with my own goods and bring you home, and feed you both ways. You will have a third of what they fetch. That is a fair offer to an orphan."
25It was not a bad offer. It was the offer of a man looking a short way ahead. Ila looked at the mounds, and then at the sea to the north, where she had never been.
26"My father paid three beads for two places," she said. "One of the places is empty now. So I have paid already, to the western quay and home again. I will sell my own beads."
27Kor laughed. Then he saw her face and did not laugh. "They will skin you," he said.
28"Then you will have the joy of watching," said Ila.
29They came up the gulf and into the mouth of the two rivers. So they came to the quay of Agade, the new city of the new king.
30She had not known there were that many ships in the world. They lay three deep along the brick: ships of the island, ships of the copper coast, river boats from the old cities stacked with wool. The noise was like surf. Men shouted in five tongues. And up from the quay, over the roofs, the house of the king stood yellow in the sun, the first she had ever seen.
31She found Shu-ilishu by asking for him, one word at a time. He was a round, tired man who had not been home in twenty years, and when she spoke to him in the speech of the eastern river his eyes filled. He heard her story in silence. Then he said, "The palace buys carnelian through a merchant named Lu-Enki. He is the only door. He is not an honest door. I will turn your words for you, but I cannot make him fair."
32"I do not need him fair," said Ila. "I need his scale."
33Lu-Enki received them in a storeroom that smelled of cedar. He was polite to the interpreter and did not look at the girl at all. He unrolled the beads from the belt, thirty-six of them, and Ila saw his fingers go still. He had never seen their like, and he could not hide it.
34"Silver by weight," he said, through Shu-ilishu. "Six shekels for each bead." He set his balance on the table. Into one pan he counted his own weights, smooth stones shaped like sleeping ducks. Into the other his servant poured chopped silver until the beam hung level. "There. Two hundred and sixteen."
35Kor, who had come to watch her skinned, drew in his breath.
36Ila put out her hand and lifted the pan of silver. She held it a moment. Her face did not change. "That is not two hundred and sixteen," she said. "It is short by one part in six."
37Shu-ilishu did not want to turn those words. She made him. Lu-Enki looked at her for the first time. "The child's hand says so. And my stones say otherwise. Shall we ask the king whether he trusts a foreign girl's hand above the weights of his own merchant?"
38You never say, trust my hand. She heard it as plainly as if he stood behind her.
39She took out the bag and set her father's cubes in a row on the table, smallest to largest. "Tell him this," she said. "I do not ask him to trust me. I do not ask him to trust my stones. Let him put my two small ones in a pan and my next one in the other, with his own fingers. Then the two of that size against the next. All the way up. He will see they agree with themselves. Then let him do the same with his."
40The merchant did not wish to. But the door of the storeroom was open, and men had gathered there. Among them was an officer of the quay, with the king's seal at his belt. Lu-Enki shrugged and did it.
41Her cubes went up the row like steps: two against one, two against one, the beam level every time. A murmur went through the men in the door.
42Then his ducks. He had two that were called the same weight, a five and a five. The officer himself set them in the pans, one against the other. The beam went down on one side and stayed there.
43No one spoke. Every trader on that quay knew what it meant when a man kept two stones of one name. One was for buying, and one was for selling.
44"Which did you weigh my silver with?" said Ila. She said it in his own tongue. It was most of the forty words.
45The officer took the light duck and put it in his belt. What passed afterward between him and Lu-Enki she did not see. But the silver was weighed again that hour, with the heavy stone, before twenty witnesses. And when the heap was right, she pressed her father's seal into a lump of clay for the merchant to keep. The one-horned bull stood up in it with its five signs. Daman had been eleven days under his mound, and he closed a bargain at Agade.
46Shu-ilishu told her later where the beads went. The king had a daughter, a priestess in the old city of Ur, who made songs. The beads were strung for her. Ila thought about that sometimes, afterward: a year of her father's patience, lying on the neck of a woman who would never hear his name.
47Kor took her home. He did not call her child again. On the crossing he let her take the star-watch beside the steersman, and found she called the turnings right.
48She did not sit down. She took her father's bench in the lower town, and since she could not drill, she hired those who could, and she did the weighing and the sailing. She made the crossing fourteen times. She taught her children the stars, and the knots in the cord, and the forty words. She taught them to test a weight against its own brothers. When she was old she kept the weights of the whole city, at the gate. And when a stranger doubted them she did not argue. She pushed the bag across and said, "Put them in the pans yourself."
49Now hear the end of it, for it is a hard end, and you should know it.
50Those cities stood seven hundred years. Then the river shifted in its bed, and the rains changed, and the ships stopped coming. The people did not die in fire. They went away a few at a time, to the villages, to the east. The drains filled. The straight streets went under the dust.
51They had marks. They cut them on seals like Daman's, thousands on thousands: the one-horned bull, and above it a row of signs. Those seals lie now in the hands of the learned in every land. Not one person living can read a single word. The names of the cities are gone. The name of their tongue is gone. We do not know what they called the river, or their gods, or themselves. A mark lasts only while there is a hand that was taught to read it. They kept the stone. They lost the hand.
52But dig in that ground today, and you will find the little cubes of banded stone. Set two of the small ones in a pan and the next one in the other.
53The beam hangs level. It has hung level for four thousand years. Whoever first made them agree is still telling the truth.
