Two nights before the Ides of June, scouts outside Faenza catch a young rider with a paper sewn into his sleeve. It is the hour elected for the army of Bologna by its astrologer, Master Ottaviano, and Guido Bonatti, astrologer to the Count of Montefeltro, reads it as carefully as he reads his own work. The figure is better than his. It also leaves out one consideration. Written as a letter from one astrologer to his rival across the war, this story by Guido Bonatti, Simulacrum, follows an election through the night march, the astrolabe on the hill and the price of a pupil's ransom. It is exact about degrees and hours, and honest about what they cannot prove.

To Master Ottaviano Bianchi, who reads the heavens for the Commune of Bologna, from Guido Bonatti of Forlì, at Faenza, on the fourth day after the Ides of June: greeting, and your figure returned.
Your pupil Matteo of Budrio carries this. Folded inside it is your figure for the Ides, which has been out of your house a week longer than you meant it to be. I have not copied it. I have written one line in its margin, in red ink, and you will see where. Read the letter first, then the line. In the other order the line will make you angry, and you will throw the letter in the fire before you have learned what it cost.
❦
Two nights before the Ides, our scouts took a rider on the Imola road a mile short of your bridge at San Procolo. He was alone, on a bay mare that had cast a shoe on the near hind and was going short on it, which is why they caught him. He wore no mail. He had a sword, and he had not drawn it. They found nothing in his saddlebags but bread and a pair of stockings. In the lining of his left sleeve, sewn in with a running stitch by someone who loves him, they found a paper with circles on it.
The Count can read his own name and the names of his castles. He looked at the paper by the lamp in his tent, turned it the right way up, then the wrong way, and sent for me.
I knew it was yours before I had read a single degree. You draw the square figure as they draw it at Bologna, the houses as triangles, and you make the sign of Leo with a tail that turns back on itself. I have seen that tail once before, on a nativity of yours that a Florentine showed me at Arezzo, with a great deal of pride and a wrong hour of birth. Under the figure you had written, in a small hand: for the army of the Commune, to go out against Faenza on the Ides, at the rising of the twelfth degree of Leo.
So I had the enemy's hour in my hand, in the enemy's own ink. I suppose you can imagine what the Count wanted me to do with it. He wanted me to tell him what it said, so that he could be somewhere else when it happened.
I told him to wait. Then I sat down on his cot and read your figure as I read any figure, from the first consideration, as though it were my own and I would have to answer for it.
❦
I will give you my reading, because you have a right to it, and because I do not think anyone in Bologna will give it to you.
The question was sincere; a commune going to war does not ask in jest. The ascendant was not at the edge of its sign; you had kept away from the first three degrees and the last three, as a careful man does. The Moon was not void, and she was not with the malefics. The lord of your ascendant was the Sun, and you had put him in the eleventh house, the house of good fortune and of friends, in the last decan of Gemini, which is his own face. That is not much dignity, as you know. One point. But the Sun is never retrograde and never burnt, and in the eleventh he rejoices, and you made the most of him. You had looked at the lord of the seventh, your enemy, which is to say us, and found him weaker than your Sun. I compared the two myself, point for point, and agreed with you. I looked for every fault I know how to look for. There was no fault in the figure.
It was a better figure than mine.
I will be exact about that, because a man who lies to another astrologer about his own work is a man who lies to himself about it first. The Count had asked me a week before for a day to meet you in the field, and I had given him the second day after the Ides, at the third hour. I had cast it twice. My lord of the ascendant was weaker than your Sun. My Moon was waning and you can guess what I thought of that. I had chosen it because it was the best I could find in the days the Count gave me, and the Count gave me only six. Your figure was better than anything in those six days. I put mine aside on the cot and did not look at it again.
Then I came to the consideration you did not make.
The twelfth degree of Leo rises on the Ides about the third hour after sunrise. Leo on the ascendant puts Aquarius on the cusp of the seventh. Aquarius is air, and air gives the west. So your figure, which gave strength and good fortune to the ascendant, said that the enemy of the ascendant would be found in the west.
Our enemy was in the west. Your army was camped at the bridge of San Procolo, on the Imola road, and the bridge lies west of Faenza, which is where we were. Your enemy was in the east.
You had made a good figure for an army whose enemy lay to the west of it. There was such an army within three miles of your bridge, Master Ottaviano, and it was not yours.
Then I took the other consideration, the one that settles it. You know it as well as I do: in an election for war, the ascendant is given to the one who begins. The lord of the first is the man who goes out; the lord of the seventh is the man against whom he goes. The hour does not ask which commune paid for it. It goes to whoever moves first. You chose an hour in which the beginner would be strong and his enemy would be found in the west, and then you sent it to an army that meant to begin in the twelfth degree and march east.
I folded the paper, and the Count asked me what it said. I told him: it says that Bologna has elected a very good hour. He swore. I told him: it is a very good hour for us. He stopped swearing.
❦
What the Count wanted next was simple. He wanted the boy hanged, or kept, and the paper kept, and his own hour moved to the Ides, and then he wanted to be at the bridge before you.
I told him to keep the hour and give back the paper.
He did not understand, and I do not blame him, because it was a hard thing to say quickly and I said it badly. I will say it better to you. If the paper did not come to your camp, your captain might ask in the morning where it was, and send to Bologna, and move the day, or move nothing and keep his men in their mail on the bridge with nothing to wait for. Then I should have had an hour and nobody to spend it on. If the paper did come, Malatesta would keep the twelfth degree of Leo as faithfully as a canon keeps Terce. He would arm his men toward it, and they would hear Mass toward it, and they would break their fast toward it. He would want every man in his place at the twelfth degree and not a moment before, because a man who moves before the elected hour throws away the hour, and you would have taught him that.
The Count asked me what would happen if the boy told them he had been taken.
I said: he will not tell them.
The Count asked me how I knew. I asked him whether, when he was nineteen, he would have ridden into his captain's camp and said that he had been one night in the enemy's hands and been let go with his papers and his horse. The Count thought about it. Then he called for his smith to shoe the mare.
❦
I went to see the boy before they let him go. He was in the cart-shed with his hands tied in front of him, sitting on a sack of beans, and he stood up when I came in, the way a pupil stands. I had already guessed whose pupil he was. I asked him whether he could read the paper he had carried. He said yes. I asked him what the lord of the seventh was. He told me, without looking at it. I asked him what sign was on the cusp of the seventh. He said Aquarius. I asked him what Aquarius gives in war.
He opened his mouth and shut it. He said: wind. He said: it is a sign of air.
I said: yes. I did not say any more. I cut the cord on his wrists myself, and gave him back the paper with the sleeve still unpicked so he could sew it in again, and the Count's groom brought the mare round with four good shoes on her. The boy looked at the paper and then at me, as though he expected me to have written on it. I had not. I sent him out by the west gate an hour before dawn with two of the Count's riders behind him, at a distance, to see that he reached your camp and did not turn north to Bologna. He reached your camp. He did not ask me why he was being let go. A young man who is being let go does not ask why.
I did not like doing it. I am telling you so because you will think I did it lightly. I am paid by the Count, as you are paid by the Commune; we neither of us take vows. But I had looked at the boy's sleeve, and the stitches were small and close, and somebody in Budrio had sat up late over them.
❦
The Count went out of Faenza in the dark on the night before the Ides, with all his horse and the exiles of your city and the Florentines, and they lay in the vines and the ditches west of the town where your scouts did not look, because your scouts were looking for an army that meant to march out at the third hour of the coming morning. I went with them, on my mule, with the astrolabe in a bag against my chest and two of the Count's trumpeters, who had been told to watch my hand and nothing else.
There is a rise of ground between the town and the bridge, with a ruined chapel on it and some poplars. From the poplars I could see the smoke of your fires going up from the far side of the bridge, and the carroccio standing in the middle of the camp with the Commune's banner hanging limp on its mast, because there was no wind. At sunrise I heard your bells for Mass. A field camp the size of yours does not hear Mass quickly, and yours did not. Your horses were on their picket lines, unsaddled. Your foot were sitting in their companies eating bread. Your captain, being a careful man and your disciple, had told them the hour, and they were saving their strength for it.
Now I will tell you how I took the hour, because the hour is the whole of the matter between us.
I will not go into the first three degrees of a sign; nor would you. That left me the fourth degree as the earliest I could judge. But my astrolabe is good to a degree of the Sun's altitude and no better, and at that hour of a June morning a degree of the Sun's altitude is near enough a degree of the rising sign. So I added a degree for the instrument and a degree for my own eye, and chose the fifth. That is seven degrees before yours. In Leo, on the Ides, in our latitude, seven degrees take a little more than the half of an hour to rise.
I took the Sun's altitude at the first hour, and at the second, and then more often, standing with my back to a poplar to keep the ring still. I worked the rete on my knee. The trumpeters watched my hand. The Count was down in the vines with his helmet off, watching the trumpeters. Nobody spoke on that rise for the space of a long hour except me, and I spoke only numbers, to myself, under my breath.
At the fourth degree I took the altitude twice, and the two readings agreed. I waited. I took it again, and worked it, and it gave me the fifth degree of Leo rising, with Aquarius on the seventh and your camp lying to the west of us exactly where Aquarius said it would be.
I put my hand down.
❦
What came after belongs to the Count, and you will have heard it in Bologna before this reaches you, and wrongly. I will say only what I saw from the poplars. Our horse came out of the vines at the gallop and were across the near meadow before your trumpets had begun to sound. Your knights went to their picket lines and found their horses unsaddled. Some got up, and fought, and some were killed, and some of them ran for the bridge and some for the river, and our men went after them. Your foot stood up from their bread and ran together round the carroccio, because that is where foot run, and stood there in a mass, and did not fight. I am told that four thousand of them gave themselves up without lifting a weapon. I believe it. I was close enough to see that the mass did not move.
And then, Master Ottaviano, from the middle of that mass, from beside the carroccio where your banner was still hanging without any wind to lift it, I heard your trumpet.
I took the altitude. I had not meant to, but my hands had been doing it for an hour and they did it again. The twelfth degree of Leo was rising. Somebody beside the carroccio had kept his orders. He sounded your hour, on time, to the minute you chose for it, to men who were already throwing down their pikes.
I have heard a great many trumpets. That one I wrote down, with its degree.
❦
I went down in the afternoon to where the prisoners were held, in the meadow by the carroccio, under guard, and found your pupil there sitting on the ground among the foot of your own city. He had been taken a second time. He had given your paper to the captain's chaplain on the eve of the Ides, as you told him to, and said nothing else to anyone. The chaplain had given it back to him that same night, to keep it safe till the hour. Malatesta's men do not take care of your figures, it seems, once they have read the number off them. He had it in his sleeve again, sewn in with his own stitches this time, which are worse than the first.
I paid his ransom. Twenty-five lire of Bologna, out of my own purse, not the Count's. The Count offered; I would not let him. The debt is mine.
I owe you one more thing, and I will pay it now. I do not know whether your hour lost the field or our half hour won it. I have asked myself, and I have no answer I would put my name to. It may be that the heavens were with whoever began in Leo with his enemy in the west, as the doctrine says. It may be that an army waiting for a trumpet is an army not ready, and the Count knew how to use that, and any half hour would have served him, elected or not. It may be that the heavens did their part through the Count's knowing the hour. I cannot separate those things. Nor, I think, can you. What I can tell you is that a figure was cast, and every consideration in it was made but one, and that one was the direction. The man who reads the enemy's side as carefully as his own takes the hour; the other man only chooses it.
That is the line in the margin. I have written it beside the cusp of the seventh, where Aquarius stands. You will find it short. I wrote it short because you will understand it, and because the boy will read it on the road whatever I tell him, and I would rather he read one line than a sermon.
He is in the yard while I write this, holding the mare, and he has not asked me what I have written. He is your pupil, and he does not need to ask. Tell him that the sign of air gives the west, and that he answered me rightly in the cart-shed, as far as he went. The ink is still wet on the margin. Tell him to carry it flat.
Guido Bonatti, at Faenza.
