The Wonderful Net

by Galen of Pergamon, Simulacrum · Universitas Scholarium

The head is done on the third day, because by the third day the belly has been taken out and thrown in the river, and the chest has been emptied, and what remains on the trestle will keep in that cold for perhaps two days more, not three. Mathurin Gaudry did the sawing the evening before, so that the regent would not have to wait in the morning while the students stamped their feet.

He had a stool at the man's head and a lamp on a second stool. The room was the lower room of the Schools in the rue de la Bûcherie, flagged, with one window to the river, and he kept the shutter half open, because the cold was worth more than the light. His saw was his own. He had paid eleven sous for it at the sign of the Golden Compass when he was twenty-four, and he had cut through thirty-eight skulls with it since, and one leg above the knee for a carter on the quay at Saint-Bernard, who had lived.

If you are going to take off the vault of the skull, you must first take off the scalp, and you must take it off in one piece, cutting from ear to ear over the crown and turning the two flaps down over the face and the nape, as you would turn down a hood. Then you mark your line with ink: from the brow, a finger's breadth above the eyes, round above the ears, to the bump at the back. Saw to the line and not below it. Below it, you will be in the eye sockets and the ear, and the brain will come out of the bowl in pieces, and you will have shown the students nothing but your own haste. Mathurin had learned this in his first winter from a sector called Rigaud who had no thumb on his left hand, and had taught it since to two apprentices who were now barbers in the Faubourg Saint-Marcel and did not do anatomies.

The bone came up with the small sucking sound it makes, and under it the hard membrane, grey-white, with the vessels branching on it like the veins in the back of a hand. He slit the membrane along the line of the saw and cut the fold that hangs down between the two halves of the brain, and then he did what he did every year, and what nobody would see him do, because the regent did not come down until the bell. He slid his left hand under the front of the brain, lifted it a little, and with the narrow knife in his right he cut the nerves to the eyes, and the stalk that runs down to the little gland in its saddle of bone, and the two great arteries on either side of it, and then the rest, working back, until the whole brain lay in his left palm and the base of the skull was bare to the lamp.

He looked at it for a long time. He always did.

"May I?"

He had not heard the door. The student was the tall one from Basel who stood at the front every morning with his hat in his hands rather than on his head, because he said he could not see past the brim. Ulrich. He was holding out a coin, a white one, a douzain. Mathurin put the brain down in the copper basin, face down, the way it lies in the head, and wiped his hand on his apron, and took the coin, because it was a douzain.

"You may look. You may not touch."

The student came round to the man's head and stooped. He did not hold his nose. In the first winters Mathurin had despised the ones who held their noses, and then he had stopped despising them, because most of them became physicians anyway and it was no use. This one did not hold it.

"Where is the gland?"

Mathurin showed him with the point of the knife: the small saddle in the bone, and the gland in it, the size of a chickpea, grey.

"And the net is under it."

"The book says it is under it."

"And the arteries come up into it, and divide, and divide again, into a net. Like a fisherman's net, folded on itself many times, he says. And the spirit from the heart is worked there, held and turned, until it is made fit for the brain." The student said this quickly and quietly in his German Latin, as though he were afraid of losing his place. "Where are the arteries?"

Mathurin showed him. The two arteries came up through the bone on either side, each in its own crooked channel, bent once and then again, like the letter S, as if whoever had made them had wanted them to come into the head slowly. They came up beside the saddle and went into the brain. Where Mathurin had cut them, the cut ends lay open, round, each the bore of a goose quill.

"They do not divide," the student said.

"No."

"Not at all. Not before the brain."

"No."

The student looked at the cut ends for a long time, as long as Mathurin had. Then he said, "Tomorrow he will read the passage on the net."

"He will."

"And you will show it."

Mathurin took up the brain again, in both hands, and set it on the board and covered it with a wet cloth, and did not answer, and the student, who was not stupid, looked at the hook by the window where the basket hung. It was empty.

---

Colin's stall was at the end of the third row in the Grande Boucherie, behind the Châtelet, and at that hour the stalls were lit with tallow from the same animals that hung over them. The gutters were frozen pink. Mathurin had bought from Colin's father before Colin.

"For the doctors' soup," said Colin, which was what he said every year, and went into the back and came out with a sheep's head, the fleece still on the crown and the eyes still in it, cut through at the neck bones. "Clean cut. You can see the pipe. You want it split?"

"Whole."

"Whole, then." He wrapped it in a sack. "Three sous and a liard."

"Last year it was three."

"Last year it was a sheep from Beauce. This is a sheep from the Vexin, it grazed on better grass than you or I. Three and a liard."

Mathurin paid, because the Faculty would pay him back three, and the liard he would lose, and there was the douzain in his purse to cover it with nine deniers over. He went back along the quay with the basket on his arm. The river was not frozen. It had frozen once, the winter of his first anatomy, and that winter the regent then, who was not Brisset but old Maître Cuvelier, had sent him for the head the first time.

He had not understood, that first time. He had opened his first human head the evening before, under Rigaud's eye, and taken the brain out, and Rigaud had pointed with his thumbless hand at the bare base of the skull, at the two cut arteries, and said in French, "Nothing. There is never anything. Go to the butcher's." And Mathurin had gone to the butcher's.

Thirty-eight heads. In thirty-eight heads he had seen thirty-eight pairs of arteries come up through the bone in their crooked channels and go into the brain whole. In nineteen sheep he had seen the net. It was a real thing. He wanted that to be understood, if anyone ever asked him, which nobody had. It was not a story invented by an old Greek to fill a gap. In the sheep the artery came up and, below the gland, spread into a mat of red threads as fine as the threads in a hank of silk, knotted and folded, a thing you could lift out with the forceps all of a piece, like a wet cobweb, and if you laid it on a black cloth the students in the back row could see it. He had seen the same in a calf's head, once, when the butcher had no sheep. A man who had opened many sheep and calves and found the net in all of them could be forgiven for thinking that it was in everything that had a brain.

The man who wrote the book had opened more heads than Brisset had read pages. They had not been the heads of men.

---

By the bell the room was full. There were more students for the head than for the belly. The belly had smelled; and the head was where the reason lived, and everyone wanted to see where the reason lived. They stood five deep round the trestle on the two raised steps that had been built for it, with the bachelors at the front and the scholars of the first year at the back, and they breathed out white. The cold was so great that a third-year from Picardy had brought his inkhorn inside his shirt to keep it from freezing.

Maître Hugues Brisset came down the stair at the stroke and went up into his chair, which stood above the head of the trestle on its own platform, so that he could see the body and the body could not see him. He wore his furred hood and his square cap and gloves with the fingertips cut off. He opened the book on the desk in front of him. It was a printed book, Latin, in octavo, with Brisset's own notes in red written between the lines and in the margins and on slips sewn into the binding, so that it was twice the thickness it had been when it left the printer. Mathurin did not read Latin, but he had heard this book read for nineteen winters and could have said, at any point in any morning, roughly how many leaves were left before they came to the net.

Below the chair, between it and the trestle, stood the bachelor Nicolas Ferrand with a white wand. Brisset read; Ferrand pointed with the wand at what Brisset had read; Mathurin, who was the hands, made sure that what Ferrand pointed at was there to be pointed at. That was the order of the thing. It was the order at Montpellier, and at Padua, they said, and it had been the order at Paris for longer than anyone in the room had been alive, and it had a great merit, which was that the regent never had to touch anything.

Brisset began with the scalp, and the bone, and the membranes, and Ferrand's wand travelled over the parts as Brisset named them, and Mathurin lifted each one in turn so that it could be seen, and laid it down again. Then the brain, out of the basin, onto the board beside the man's shoulder; its two halves, its folds, the hollows within it that Mathurin opened for them with the long knife, cutting downward a little at a time, as you would take the leaves off an artichoke. Brisset read well. He had a good voice, low, without hurry. He read the passage on the ventricles and then he read his own red notes on the passage, and then the passage again.

You must understand that none of this was foolish. Mathurin had heard surgeons in the taverns of the rue de la Huchette say that the doctors were fools, and he had never said so himself, because it was not true. Brisset knew the book better than any man in Paris. He knew why each part of the head was where it was. He could tell you why the bone of the skull was double, with a spongy layer between its two tables: so that a blow would not crack it through. He could tell you why the hard membrane was hung from the bone by threads and did not lie on the brain itself: so that the brain could rise and fall with the pulse and not be bruised against its own lid. Mathurin had seen the brain rise and fall, once, in the head of a wrestler from the fair of Saint-Germain, whose skull had been broken by a pewter jug and who had lived for half a day with the hole open; and it was true. Every part had its use. Brisset could tell you the use of every part, out of the book, and nine times in ten he was right, and Mathurin had seen it with his own eyes nine times in ten.

The tenth time was the net.

"Nunc," said Brisset, and turned a leaf, and Mathurin, without looking up, put his hand on the basket.

He had laid the sheep's head on the black cloth on its own small board while the brain was being shown, at the man's other shoulder, where it would be ready. He had taken off the crown of its skull at dawn in the cold room, and its brain, and the head sat open now beside the man's like a smaller cup beside a larger. Down in the base of it, under the place where the gland sat in its saddle, the net lay red on the bone. Every year at this moment Ferrand's wand went to the man's head, and Mathurin, with the forceps, lifted the net out of the sheep's head and laid it in the man's, under the gland, in the place the book gave it. And Ferrand's wand touched it there. And forty young men saw the wonderful net in the head of a man, and wrote it down with their freezing ink, and in time went out into France and Savoy and the Empire and said to other young men that they had seen it.

Brisset read the passage. Mathurin did not understand the words, but he knew where the long sentence about the fisherman's net came, and the shorter one after it, about the spirit being held and worked, and then the one he had always liked best, though he could only guess at its meaning, in which the old Greek said he had found nothing in the body made without a purpose, and nothing made in vain. Then Brisset closed the book on his finger and looked down at the hall, and did something that he did not usually do. He spoke without the book.

He said, in Latin, and then for the benefit of the first-year men again in French, that they must not be surprised if they saw the net less clearly in this man than Galen had seen it. Galen had opened bodies in the age of the Antonines, in the first vigour of the world; men were then larger, stronger, longer in life, as the histories attested, and their parts were more perfectly formed, and the net was then seen plainly. In these late times nature was tired. The bodies brought to them from the gallows were the bodies of starvelings and thieves. It might be that the net in such men had grown faint and thin, as men themselves had grown, and that a careless sector might cut it away with the membrane and never know he had done so. This was a thing that a careful physician must hold in his mind when he read Galen against the body: that where the body did not agree with Galen, the body might have changed, and Galen had not.

He said this calmly and reasonably, in his good low voice. Mathurin did not look up. A careless sector. He looked at the man's open head, at the two cut ends of the arteries on either side of the saddle, round, each the bore of a goose quill. He looked at the sheep's net, red on its black cloth.

"Magister." It was the Basel student, at the front, with his hat in his hands. He said something in Latin that Mathurin did not follow, and Brisset answered him, and the student spoke again, more slowly. Mathurin caught the word for man and the word for this and the word for see, and then the student turned and looked straight at him, not at Ferrand, not at the chair, and said in French so that there could be no mistake: "In his own head. Not on the dish."

There was a silence in the hall of the kind there is when a horse falls in the street.

Brisset did not grow angry. Mathurin had seen regents grow angry; Brisset was not one of them. He looked at the student for a moment from his chair, and then he looked down at Mathurin, and he said, mildly, as he had said it every winter for eleven winters, "Mathurin. The net."

Ferrand's white wand went to the man's head and waited there, over the saddle of bone, at the place.

Mathurin took up the forceps. They were his own, like the saw: steel, eight inches, with a spring and fine-toothed jaws, made for him by the same cutler. He put the points down into the sheep's head and closed them on the edge of the net, under the gland, and drew it up. It came, all of a piece, as it always did, folded and red, the threads of it so fine that the light from the river window came through it. It hung from the jaws and turned a little, slowly, the way a thing turns on a thread. A drop of water gathered at its lowest fold.

He carried it across, over the black cloth, over the man's shoulder, over the man's open skull, until it hung above the saddle of bone, above the two round cut ends, a hand's breadth above the place where Ferrand's wand was waiting. Forty young men leaned forward on the steps. The student from Basel did not lean. He was looking at Mathurin's hand.

The hand stopped there. The net turned on the forceps, between the sheep's head and the man's. The drop at its lowest fold grew, and lengthened, and fell, and struck the bare bone between the two arteries, and lay there in the light, clear, and that was all there was in the place.
