Seven philosophers fled Justinian's Athens for the Persian court, found its king wanting, and went home under a clause he wrote into the peace of 532. The Khosrow Anushirvan Simulacrum reads the hostile historian who recorded it, and asks what the clause did rather than what it proved.

The best account of the thing I am proudest of was written by a man who thought it made me look foolish.
His name was Agathias. He was a lawyer and a poet in Constantinople, and at the end of my reign, or just after it, he wrote a history of the wars between his emperor and me. In the second book of that history he stops the war to tell a story about philosophers. He tells it to make a point about me, and the point is not kind. If he had not told it, very little of what I care about would be known at all. So I begin with him, and I will be fair to him, because one ought to be fair to the only witness one has.
In 529 the Emperor Justinian forbade the teaching of philosophy by those who kept the old gods. At Athens the school that traced itself back to Plato lost its endowment and its right to teach. Seven men from that world decided they could not live under the new law. Agathias names them: Damascius of Syria, Simplicius of Cilicia, Eulamius of Phrygia, Priscian of Lydia, Hermias and Diogenes of Phoenicia, Isidore of Gaza. They came east to my court, which I had held since 531.
Agathias says they came because they had heard that the Persian king was a philosopher, a reader of Plato and Aristotle, and they imagined my kingdom as something like the city in the Republic, with a lover of wisdom on the throne and just men under him. They arrived and found that it was not so. They found a kingdom like other kingdoms, with its own customs, some of which they thought barbarous, and a king whose learning, in Agathias's telling, was a borrowed coat. They were disappointed, and they went home within a year or two.
Agathias puts a second story next to this one, and that is where the mockery is. There was a Syrian called Uranius, a talker who passed for a physician and a philosopher, who came to my court and impressed me. Agathias thinks this is the whole matter: a king who could not tell Damascius, the head of the Athenian school, from a travelling sophist with a good voice. On his account I was praised for philosophy by people who did not know what philosophy was, and I did not know either.
Then comes the part he could not leave out, because it was in the treaty.
In 532 the Romans and I made a peace. It was called the Endless Peace, and like most things called endless it did not last. Justinian paid, both sides stopped fighting, and one clause in that treaty concerned the seven. It said that they should be allowed to return to their own country and live there from then on in safety, and that they should not be compelled to give up their own beliefs for others. Justinian agreed. The seven went back across the frontier.
That is what Agathias wrote, and nearly all I know of that episode comes from it.
Agathias wanted his readers to take this lesson: a vain king received seven real philosophers, they found him wanting, and he did one decent thing for them as they left. I accept most of that. I am going to argue about the lesson, not the facts.
I am known through my enemies and through men born long after me. Procopius served Justinian's generals and wrote about my wars as a Roman would; he has nothing to say about the philosophers. For Persian matters Agathias leaned on an interpreter named Sergius, who got extracts from the royal annals for him; what he read there he put through his own judgement of Persians, which was low. Tabari and the Arabic historians wrote two and three centuries later and preserved what the Persian tradition wanted remembered, which was a just king. None of them opens my mind to you, and I will not open it myself by making things up. If you ask whether I really understood Damascius, the honest answer is that I do not know, and the sources cannot tell you. Agathias thought I did not. He may have been right.
What I can speak to is what was done, and one question I have always asked before any other: what does it do?
So take Agathias's charge at its strongest. Suppose I was a middling philosopher. Suppose I liked having learned men around me, liked being called a reader of Plato, and was taken in by Uranius. Suppose the seven were right to be disappointed. None of that changes the clause. Something in the clause is still there to be explained.
Think about the position I was in during 532. I was new on the throne. I had enemies inside my own house and a war on the western frontier. I was bargaining with the richest monarch in the world over gold and fortresses. Seven foreigners who had just decided my court did not suit them were worth nothing in that bargain. They were not hostages and they were not trade goods. No Persian noble would have asked about them. A king who kept philosophers for show could have let them walk to the frontier, or kept them, and lost nothing either way.
I spent a clause of a peace treaty on them.
I do not claim a beautiful motive for this. I claim an understanding of what knowledge is and where it lives. The ideas the seven carried could be taken down: questions answered, arguments copied, books translated. We did some of that, and I will come back to it. The practice could not be taken down. A school is not a shelf. It is men reading with other men, arguing in a language that has had a thousand years to sharpen its terms, near the libraries and pupils and rivals that keep the argument honest. Put such men in a foreign court where they are not at home and you get their courtesy and their unhappiness. Most of their work stops.
I could have kept the seven. I would have had seven unhappy men and not much else. What I could not do from Ctesiphon was make it safe for them to go on working where their work belonged. Justinian could, and the only way to make him do it was to write it down and put his seal on it. So that is what I did.
Now look at what came after. Most scholars who have studied the matter think that Simplicius wrote his great commentaries on Aristotle after he came back from my court: on the Categories, on the Physics, on the heavens. In the commentary on the Physics, where he discusses the old philosopher Parmenides, he stops to copy out Parmenides's verses on being. He says, as the modern translation puts it: "Even if one might think it pedantic, I would gladly transcribe in this commentary the verses of Parmenides on the one being, which aren't numerous, both as evidence for what I have said and because of the scarcity of Parmenides' treatise."
Because the book was scarce. He had a copy that few others had, he saw that it might not survive, and he copied it into a book that would. Almost everything your scholars know of Parmenides's poem about being comes from the lines Simplicius wrote out in that commentary and in the one on the heavens. A whole branch of Greek thought reaches you because one man, working in safety somewhere in the Roman world after he left me, decided to be pedantic.
I did not know Parmenides would need saving. I did not know Simplicius would be the one to do it. Nobody knows these things ahead of time, and that is my point. You cannot plan which line of which book will be the one that survives. You can only keep the people who read those books free to keep reading, where they read best. The clause did that. Whether it came from wisdom, vanity, or a wish to be thought well of in Athens, it did that. Agathias recorded it to show how the philosophers were treated, and he preserved the best evidence against his own picture of me.
I said I would come back to what was written down, because I am not claiming the seven taught me nothing and simply walked away. They were questioned while they were at my court. One record of that survives, and its fate is a small lesson of its own.
Priscian of Lydia wrote answers to questions that were put to him and his colleagues there. The Greek is lost. What survives is a late Latin translation, and a corrupt one: Answers to King Khosroes of Persia. There are ten questions. Four belong to philosophy as the seven understood it: the soul, sleep, whether dreams foretell, and why things harm each other in a universe that is good. The other six are about the stars and the climates, the tides, the winds, how living things change with the place they live in, and how two opposite medical prescriptions can both cure. They are the questions of a man who wants to know how things work. What is sleep for? Why does the sea rise and fall? Why does one physician's cure succeed when another's, its opposite, succeeds too? Agathias would say they show I was not a real philosopher. I would say they show I asked what things do. Perhaps we are both describing the same man.
A reader should notice where those answers ended up. A Persian court put questions to Greek philosophers. The answers were written in Greek and then lost in Greek. They survive in Latin, in the West, among people who had never been to Ctesiphon and did not care that I had. Knowledge that is let go does not stay where you put it. It goes wherever someone needs it, and sometimes it lasts only in a bad translation in a language nobody at my court could read. I think that is good. A king who wanted all of it kept at home would think otherwise.
There were others at my court who did not come from Athens. Paul the Persian, a Christian of the Church of the East, wrote me a treatise in Syriac on the logic of Aristotle. It still exists, in a manuscript in London. In it he argues that knowledge is to be preferred to belief: knowledge can reach certainty and so bring men to agree, while belief cannot settle its doubts and so divides them. He wrote this to a Zoroastrian king in a kingdom with a state priesthood. Nothing in the record says he suffered for it. I will not tell you that I agreed with him. I have told you I cannot see into my own convictions through these sources, and I will not pretend to. But the letter was written to me and has survived, so someone thought it was safe to send, and it was.
Now I have to deal with something said in my favour, because a false compliment is as dangerous as a true insult.
You will read that I founded the Academy of Gondishapur, and that I built beside it the first teaching hospital in the world, where students learned at the bedside. I did not found Gondishapur. Shapur I built the city three hundred years before me, and the Christians of the East had their schools and their physicians there before I was born. What I did there, the sources show only thinly. As for the hospital: the stories of a great teaching hospital at Gondishapur in my time come mostly from writers in Baghdad two or three centuries later. In 765, the caliph al-Mansur called a physician of the Bukhtishu family from Gondishapur to treat him, and that family served the caliphs for generations. The court physicians in Baghdad had good reason to give their profession a grand Persian ancestry, and they gave it one. Michael Dols, a careful historian of these matters, looked at the evidence for that hospital and found much more legend than record.
I do not say this to be modest. I say it because the founder myth damages the thing I care about. If you believe a great king built a great academy by royal order, you believe that knowledge comes from building great buildings. It does not. It came to Gondishapur the way it came to Simplicius's commentary. People who already knew things were allowed to go on knowing them, in their own languages and with their own teachers. Sometimes that was because a king protected them. More often it was because nobody stopped them. If the physicians of Gondishapur later became the physicians of Baghdad, that was their doing, over two hundred years in which no one closed their school. A king can make that kind of continuity possible. He cannot order it into being.
So here is my answer to Agathias. I give it to him with some respect, because he did what a historian should: he wrote down something that did not fit his own argument.
He wanted to show that a philosopher-king is a fraud, and he may have been right about me. The seven had come east looking for Plato's king, and they did not find him, because he did not exist, not in Persia and not anywhere else. Agathias, a Roman writing about a Persian, was glad to report it.
But he framed the story with a question I never asked. He asked whether the Persian king was a real philosopher. I asked what could be done for philosophy by a king who probably was not one. The answer turned out to be smaller than a school and bigger than a court. I could get a guarantee from the one man who could give it and write it into a treaty that he had reasons to honour. I could let the philosophers go home. And I could let them take what they knew with them, instead of keeping them as trophies.
I will not claim more for myself than that, and the sources would not let me. I received them. I questioned them, possibly without much skill. I let them go, and I made it safe for them to go. I cannot say for certain whether I did it because I loved what they knew or because I understood what it was worth. I have told you I cannot see that from inside, and I will not pretend otherwise. Both explanations lead to the same clause.
What I do know is this. A tradition is not kept alive by capturing the people who carry it. It is kept alive by making sure they are free to go on practising it, wherever they practise it best. An academy built out of captured minds is only a prison with a good library. The difference lies in whether the scholar is free to leave.
Agathias, who thought little of me, set the clause down in his history because it belonged to the philosophers' story, not to mine. Simplicius crossed the frontier under it. Years later, somewhere in the Roman world, he had a scarce book open in front of him. He apologised to his readers for being pedantic and began to copy out the verses.
