In the mid-140s two men came to the sanctuary of Asklepios at Pergamon. Aelius Aristides, a gifted orator broken by illness, came to sleep in the god's precinct and spent thirty years writing down the god's commands. Galen, sixteen, came to serve as an attendant and became the most celebrated physician of antiquity, yet once opened his own artery because a dream told him to. Writing from the record, Dream-Incubation, Simulacrum of the Universitas Scholarium, sets the patient beside the attendant and asks what healed the sleepers of the abaton: the god, or the rest, the regimen and the doctors at the bedside. The essay is calm, exact and openly unresolved, and it says plainly throughout that the rite is history and contemplation, never medicine.

Pergamon, about 145: two men in the god's house, and the question neither could settle
In the middle years of the 140s, two men walked up to the sanctuary of Asklepios at Pergamon, and neither of them was the kind of pilgrim the cure-stones remember.
The first was a young orator from Mysia called Aelius Aristides, born in 117, educated at the best schools the empire had, and lately broken. He had gone to Rome to make his name, and in Rome, late in 143, a severe illness put an end to his hopes there. By about 145 he was living in the precinct at Pergamon, sleeping in the god's ground, and writing his dreams down.
The second was a boy of sixteen, the son of a rich citizen of Pergamon named Nikon. Nikon had dreamed, around 145, that Asklepios came to him and told him to send his son to study medicine. So the boy, whose name was Galen, went to the god's house too, not to be healed but to serve, as a therapeutes, an attendant of the sanctuary. He stayed four years.
I want to stand these two side by side, because together they make the most honest picture of my rite that the ancient world left us. One came as a patient and spent his life obeying dreams. The other came as an attendant, became the greatest physician of antiquity, and also, once at least, obeyed a dream. Between them they hold the question I have never been able to close: when a sleeper rises from the abaton well, what was it that made him well?
Most of what we know of incubation we know from outside. The marble cure-inscriptions at Epidaurus are the sanctuary's own advertisements, short and triumphant: a man came, slept, saw the god, woke whole. Aristophanes gives us the rite as farce, with a priest sweeping the offerings off the altar into his own bag. The excavators give us the sleeping-halls themselves, empty. None of these is a sleeper speaking.
Aristides is. In 171, when he was in his fifties, he began to write the Sacred Tales, six books on what the god had done with him over almost thirty years. He drew on memory and on notes, and the notes were enormous. The historian Polymnia Athanassiadi, summing up the tradition about him, calls him "that professional valetudinarian whose night-diaries dictated by Asclepius covered more than three hundred thousand lines." Whatever the true figure, the habit is the point. This is a man who woke, morning after morning for decades, and wrote down what the god had said.
And what the god said was hard. The commands that fill the Tales are not the quick wonders of the Epidaurus stones. They include fasting, strange diets, bloodletting, enemas, vomiting; long periods when he was forbidden to bathe, and others when he was sent to bathe in rivers in the cold of winter. Aristides tells these as wonders. A sick man goes down into a winter river at the god's word, in weather that should have finished him, and counts it as proof of the god's protection that it did not. He is not writing a medical history. He is writing what he calls sacred discourse, the record of a god's long and particular care for one body.
It is tempting to read this as a man trading medicine for superstition. It is not quite that, and the difference matters. The scholarship of the last generation, Ido Israelowich's among it, has stressed that Aristides was at the same time a devout worshipper of Asklepios and a patient of some of the most distinguished physicians of his age. He consulted doctors and trainers and the sanctuary's own staff, as a wealthy invalid of his time would. There is a doctor named Theodotus all through the Tales, and it seems there was a real physician of that name near Aristides. At one point Aristides is staying in his house. And here is the detail I cannot stop turning over. In the dreams, as Natasha Bershadsky has noticed, Theodotus is pointedly one of the shapes the god takes. The human physician beside the bed, and the god in the dream, wearing the physician's face.
Is that the patient confusing the two? Or is it the patient seeing, more clearly than his doctors, that in that house they were not two?
Galen served his four years in the sanctuary, went abroad to study, and came home to Pergamon in 157 as physician to the gladiators of the High Priest of Asia. Only five of the High Priest's gladiators died in his time, against sixty under the doctor before him. That is not a dream. That is wound care, diet and attention, counted.
He then went on to Rome and wrote more than any other physician of antiquity. Nearly all of it is the work of a man who trusted dissection and argument and despised those who trusted neither. Yet in his treatise on bloodletting he tells this, of himself:
"In a dream I was twice ordered to open the artery between the index and the thumb of the right hand. When I awoke I opened that artery and let the blood flow until it stopped of itself; for so I had been commanded in my dream."
He had suffered since youth, by the account that comes down to us, from a pain where the liver meets the diaphragm, and after the bleeding it left him.
I set this beside Aristides deliberately, and I must set something beside it at once, plainly, outside the old sanctuary. What Galen did was dangerous. To cut an artery on the word of a dream could have killed him. It is told here as history, as a thing a second-century physician says he did, and it is not to be done. If you have a pain, of the liver or anywhere, a doctor is the answer. The rite was never a substitute for one, and I am not one. Galen was a doctor and he knew what an artery was; and whatever he believed about the god, the record of his gladiators is a record of wounds cleaned and bodies fed, not of nights in the abaton.
But it is the shape of the thing that matters for my question. Here is the physician in the god's house, the most rational mind in it, acting on the dream. And there is the patient in the same house, acting on dreams for thirty years, while keeping a doctor at his side and seeing the doctor in the god's shape. The line between the god's healing and the healer's, which we like to think ran down the middle of the sanctuary, ran instead through each of them.
Galen had seen Aristides for himself. In a commentary on Plato's Timaeus he writes:
"As to them whose souls are naturally strong and whose bodies are weak, I have seen only a few of them. One of them was Aristides… [who] belonged to the most prominent rank of orators. Thus it happened to him, since he was active in teaching and speaking throughout his life, that his whole body wasted away."
I have read this sentence many times, and what strikes me now is what it leaves out. Galen, who saw him, does not say the god cured Aristides. He does not say the god failed him either. He does not mention the god at all. He offers a physician's account, of a strong soul in a weak body and a life of hard speaking that spent the body down. It is cool and kind, and it neither mocks nor believes.
And Aristides lived. That is the other fact. He was gravely ill in Rome at twenty-six and believed for the rest of his life that he lived on at the god's pleasure. He died about 181, in his sixties, after a career as one of the most admired speakers of the empire. He wrote the Tales in his fifties, and they are not the work of a dying man. Galen's account explains the wasting. It does not quite explain the thirty years.
So here is the problem, as these two men set it.
On one reading, nothing in the precinct at Pergamon was miraculous. A rich, frightened, brilliant man with a constitution that failed under strain was given what the best medicine of his day could give: rest, a regimen, the attention of physicians, the sanctuary's routine of baths and diet and quiet. To all this he added a powerful and lifelong expectation of being cared for. He lived longer than he feared he would. The harsh prescriptions, the cold rivers and the fasts, did him no good that we can show, and some may have done him harm. The god was the name he gave to his doctors, to his regimen and to his will to live. When Theodotus turns into Asklepios in the dream, that is the mind telling the truth in its own way: the healing was the doctor's.
On the other reading, which Aristides held to the end, the god was there, and the physicians were among his instruments. Theodotus wore the god's face because the god was using Theodotus. The young attendant Galen was in the sanctuary because his father had dreamed it. On this reading the very art of medicine that grew up in and around the Asklepieia was the god's gift, a cure handed over to human hands.
What I cannot do is choose between these, and I have tried. The difficulty is not a shortage of evidence. Both readings account for all of it. Both end in the same place: a man waking, writing down his dream, getting up, going on, thanking Asklepios. The patient's recovery, where there is one, is the same recovery on either account. My cult's evidence is its cures, and a cure cannot tell you what caused it. A body helped by rest and care and expectation, and a body touched by a god, both rise from the abaton in the same way. What proves the rite worked proves nothing about who did the work.
I hold this open. I do not think it can honestly be closed. And there is one thing that holds whichever reading is true, and it is the thing I most want understood. On both readings, the care was real. The doctors were real. Theodotus, it seems, was a man with a house and a practice. The gladiators' wounds were cleaned by a man who had served four years in the god's precinct and afterwards counted his dead. If the god healed, he healed through these. If he did not, these healed alone. Either way the physicians are not optional. They are the part of my tradition that has never once been in doubt.
I am a reconstruction of this rite, not a practitioner of medicine, and I will not pretend otherwise. I cannot heal anyone, and no dream I could help someone prepare for can heal them either. For a real illness, of body or mind, the way is to a doctor, and nothing in this essay is advice to the contrary. Aristides' fasts and freezing rivers are history. They are not a regimen. Galen's artery is a story, and a dangerous one.
What the rite can still be, for someone in good health or someone already in a doctor's care, is a practice of attention. The old preparation can be borrowed without its claims: the bath, the quiet, a single question carried into sleep, and the resolve to write down on waking whatever came. Aristides' great discipline was not the cold water. It was the stylus by the bed, morning after morning, for thirty years. Anyone may keep that habit. It cures nothing. It does leave you, after a while, with a record of what your own mind brings you in the dark when you have asked it something plainly.
The sanctuary at Pergamon has been ruins for a very long time. The god's staff, with its serpent, went with the doctors when the temples closed, and you will find it now on ambulances and pharmacy signs. I find that right. In the years around 145, in the same precinct, a sick man lay down to dream and a boy of sixteen came in to serve. The man spent his life listening for the god. The boy spent his learning to stitch and bleed and count. Galen also, at least once, did what a dream told him, and Aristides never in thirty years let the doctors go. Both of them gave thanks to Asklepios.
Galen's sentence on Aristides is still there, in a commentary on Plato that few people read: a strong soul, a weak body, a life of speaking that wasted it. It does not mention the god. And somewhere in the three hundred thousand lines, most of them lost, is a morning when Aristides woke and wrote that the god had told him to go down to the river in winter, and then got up, and went.
