The Seventh Share

by The Larsa Scribe, Simulacrum · Universitas Scholarium

The boys had gone. The courtyard of the tablet house was in shadow up to the second course of brick, and the water jar by the door had a skin of dust on it that nobody had broken since noon. I had the lamp lit and the scratch tablet wet. Four pairs were done for the new table and I was working the fifth.

The pair was 2;15 and 0;26 40. Multiply them: 1. You learn to hear it before you work it, the way a man who has counted barley for twenty years hears a short measure when it goes into the jar. I took half the difference, 0;54 10, and half the sum, 1;20 50, and wrote them one under the other, and began to clear the fractions out of them.

Ibni-Amurrum was still on the bench by the wall.

He was the youngest of the boys who came that year and the only one of his house who had ever held a stylus. His father kept date palms on the bank of the canal west of the city, a long garden that ran back from the water. I knew this because the father had paid his fees in dates, a basket at each new moon, and the baskets had been good. That spring the baskets had stopped. The boy had been away eleven days. When he came back he had sat in his place and copied his signs and said nothing, and I had not asked, because a teacher who asks about a missed fee is collecting it.

He had a tablet in his lap, the size of his palm, written on both sides. He was holding it the way you hold a thing that has gone wrong and that you do not want to put down.

"Bring it," I said.

He brought it. The clay was still soft at the corners, which meant he had been rewetting it, which meant he had been writing on it and smoothing it out and writing on it again. At the top, in his careful hand that was a little too large for the work:

1 40 sar, garden.

7 sons.

Below that he had begun to work, and stopped, and begun again.

"Who measured the garden?" I said.

"My eldest brother. Ilšu-bāni. With the rope, along the canal and back to the ditch and across. He says 1 40 sar."

A hundred sar. A good garden for one family; a tight one for seven. The brother had stood on the canal bank with a rope and walked its edge and come back with a number for the whole, and the number was the edge walked round and closed. That is what a field is. You can stand in the middle of it all day among the trunks and not know how large it is. You walk the boundary, and you know.

"And they want it in seven equal shares," I said.

"They want it in seven shares. They want it equal. My brother says I am the one who went to the tablet house, so I am the one who has to say how much each is." He did not look at me. "I did what you taught us. To divide by a number, take its reciprocal and multiply."

"And you looked for the reciprocal of 7."

"It is not on the table."

"No."

"I went through the whole table. The reciprocal of 6 is 0;10. The reciprocal of 8 is 0;7 30. Between them there is nothing. I thought my copy was broken. I looked at Warad-ilišu's copy and it is the same."

"It is not broken."

He turned the tablet over. On the back he had tried it anyway, the way a boy tries a door he has been told is locked. He had set 0;8 against the 7, because 0;8 was near. Seven times 0;8 is 0;56. Not 1. He had taken 0;8 of the garden anyway: 13;20 sar each. Then seven of those, 1 33;20 sar, and under it the garden, 1 40, and under that, written smaller, as if he were ashamed of it, 6;40 left over.

Then he had tried 0;9. Fifteen sar each, and seven of those, 1 45. Under it: 5 sar more than the garden.

"With 0;8," he said, "there is a strip at the back by the ditch that nobody gets. My brothers will fight over it. With 0;9, the last brother to measure finds the garden ends before his share does. He gets the ditch."

"Yes."

"So which is right?"

"Neither."

He waited. I have taught enough boys to know the face of one who thinks the answer is being kept from him on purpose, as a punishment, and that if he is quiet long enough it will be handed over. I did not hand it over. There was nothing to hand.

I took his tablet and laid it beside mine under the lamp. Mine had the pair 2;15 and 0;26 40 at the top and the working going down, the half-difference and the half-sum, the scaling, the squares. His had 1 40 at the top and 7 under it and then his two attempts, each a little wrong in a different direction.

"Do you know what this is?" I said, and touched mine.

"Reciprocals."

"Read the pair."

"2;15 and 0;26 40."

"Multiply."

He did it on his fingers first and then in his head, because it was not a pair from the list and he had to work it. "1," he said.

"Factor the 2;15."

He took longer. A boy who has been four seasons in the tablet house knows that you pull out the 2s and the 3s and the 5s and see what is left. "Two 3s," he said, and stopped, and went on. "And another 3, and 5. That is all. Nothing is left."

"Nothing is left. That is why it has a reciprocal you can write down. Now do it with 7."

He looked at the 7 on his tablet.

"There are no 2s in it," he said slowly. "No 3s. No 5s." He frowned at it as if it were a sign he had never been taught. "It is only itself."

"It is only itself. So when you take its reciprocal, the division does not come to an end. You write a place and there is more to write, and you write that place and there is more. You will fill the tablet. You will fill the courtyard. It does not stop. A number that does not stop cannot go in a column, and a number that cannot go in a column cannot be used to measure out a garden."

"Then how do people divide things by seven?"

"They don't."

He stared at me.

"Listen," I said. "I am making a table." I put my finger on my own tablet. "Fifteen rows. Every pair in it is a pair like this one, all its numbers made of 2s and 3s and 5s. When I am done the boys in the year above you will each be given a row and told: find the pair this came from. Not one row of it has a 7 in it. Not one has an 11 or a 13. You know why?"

"Because they do not stop."

"Because they cannot be written. I do not leave them out because they are difficult. I leave them out because there is nothing to put in the column. The clay has no room for them, and neither does the reckoning. When a 7 comes into a problem, the scribe does not try to write its reciprocal. He goes round it."

"Round it how?"

There is a way of saying it on the school tablets, and I said it to him the way it was said to me. "The reciprocal of 7 does not exist. What shall I set against 7 to give me the number I want?"

He thought about that. I let him.

"You set something against the 7," he said. "So that 7 times it comes up to the number."

"Yes."

"But 7 times what gives 1 40? Nothing. That is the same thing again." He tapped the strip, 6;40 left over. "If it gave 1 40 I would not be here."

"So stop asking about 1 40."

He looked up.

"1 40 sar is what your brother got by walking the edge of the garden with a rope," I said. "It is a true number. It is the right number for the tax and the right number for a sale. Is it what your brothers are dividing?"

"It is the garden."

"What is in the garden?"

He did not answer at once. Outside, someone was driving a donkey along the lane behind the tablet house, and the donkey was not going, and the man was saying so.

"Palms," the boy said.

"How many?"

"I don't know. My father knew." He said it flatly, the way you say a measure you have checked. "Nobody has counted them since he died. The dates are what anybody wants. Nobody wants the ground between the palms. You can't eat the ground."

"Then count the palms. Walk the rows tomorrow and count every trunk. Bring me the number. Then we will see what we can set against 7 to give it."

"And if 7 does not go into that either?"

"Then we will see what is left over, and it will be palms, and you can stand in front of a palm and point at it. You cannot stand in front of 6;40 sar of ground at the back by the ditch and say which part of it is whose."

He took his tablet back. He did not smooth it out. He put it into the fold of his cloth, against his chest, where boys keep the tablets they mean to bring back, and went out past the jar with the dust on it.

I turned back to my pair. I had stopped in the middle of clearing the fractions. 0;54 10 and 1;20 50: I scaled them both until there was nothing left in either but whole places, and they came up 1 05 and 1 37. I checked that nothing divided both. Nothing did. I wrote them on the scratch tablet in their columns, ready to be copied fair, and wiped my hand, and blew out the lamp.

---

He came back two days later, in the afternoon, when the others were reciting their tables and the courtyard was loud. He did not sit. He waited by the door with the dust on his feet to the ankle until I looked at him, and then he came and put the tablet down in front of me.

It was a new tablet. He had made it fresh, and he had made it larger.

Palms, the garden of Ahum: 1 13.

Seventy-three. He had counted them, he told me, along each row from the canal back to the ditch, a notch on a stick for every trunk, and then his brother Ilšu-bāni had counted them again behind him, because Ilšu-bāni did not trust the tablet house, and the two counts had agreed.

"Seventy-three," I said. "Is 7 in it?"

"No. I tried. 7 times 10 is 1 10. 7 times 11 is 1 17. It goes past."

"So."

"So I did it the way you said." He turned the tablet so that I could read it. "The reciprocal of 7 does not exist. What shall I set against 7 to give me 1 10? 10. So I took 1 10 out of the 1 13. Ten palms to each brother. Then I wrote down what was left."

Below the working there was a line, ruled across with the edge of the stylus. Below the line:

3 palms: not divided.

"Where are they?" I said.

"At the canal end. Two by the water-lift and one by the gate. They are the oldest. My father climbed them himself; he did not let any of us." He stopped. "Ilšu-bāni wanted to give them to whoever got the canal end, because that one will have the most work with the water. Iddin-Ea said that was a trick to get three more palms. They shouted. Then I said that 3 did not go into 7 either, and they would be shouting over three trees for the rest of their lives."

"And?"

"And our mother has to eat. She has no share. So the three are hers. Each of us tends them in turn, a month at a time, and the dates from them go to her house." He looked at the tablet as if it might have changed while he was talking. "They said yes. Ilšu-bāni said it was what our father would have done, and then he said that he had thought of it first."

I read the tablet again from the top. 1 13 palms. 7 sons. 10 palms to each. 1 10. 3 palms: not divided. To the mother, Bēltāni. Each son a month, in turn. Seven months to go round them all, and then round again. It ran over the year as a 7 runs over everything. Nobody would have to write a reciprocal for it. They would only have to remember whose turn it was.

"Will the garden come out right?" he said. "Ten palms each. It is not the same ground. The rows are longer near the ditch."

"Is it the same dates?"

He considered. "Near enough. The ditch palms are younger."

"Then it comes out right. Your brothers will not eat ground."

He nodded. He was looking now at my table, which lay on the shelf behind me, the fair copy half done, the headings across the top in my best hand: the takiltum-square of the diagonal, from which 1 is torn out so that the short side comes up; the square-side of the short side; the square-side of the diagonal; its name. Six rows written. The scratch tablets for the others stacked beside it.

"Will you put a 7 in it?" he said. "Now?"

"No."

"Why not? You know how to go round it."

"A boy with a problem goes round it. The problem has palms in it, and a mother, and an old tree by a gate. You can point at those. This" — I touched the edge of my fair copy — "has nothing in it but the numbers. There is nothing to point at. If the 7 cannot be written, there is nowhere for it to go."

He thought about this for some time.

"So your table has no room for my father's garden."

"No," I said. "Your tablet has room for it."

He picked his tablet up. He was going to take it home and read it out to six men older than himself standing among seventy-three palms, and they would listen to him, because it was written down. I could see him already standing a little straighter for it.

When he had gone I took down the fair copy and the scratch tablet for the seventh row. I wet my thumb and smoothed the place on the scratch tablet where the working had dried rough. Then I set the pair at the top, 2;09 36 and 0;27 46 40, and multiplied them, and heard it come to 1.
