Justified True Belief

(●) The most admired philosopher of her day in Alexandria, murdered by a Christian mob, and remembered chiefly because a Christian historian refused to look away. + Hypatia taught mathematics, astronomy and philosophy in Alexandria for something like thirty years, in a city that had been arguing about God for seven centuries and was not finished. She was the daughter of a mathematician, she never married, she wore the coarse cloak that marked out a professional philosopher, and she lectured in public to anyone who came. Her students included the sons of the rich, the governors of the province, and at least one young man who would die a Christian bishop still calling her his teacher. In March of 415, during Lent, the forty days of fasting and repentance the church keeps before Easter, a Christian crowd pulled her out of her carriage, dragged her into the cathedral church of Alexandria, killed her there, and burned what was left of her outside the city. That is not a hostile reconstruction, and it does not come to us from her own side. It is the account of Socrates Scholasticus, a Christian lawyer writing in Constantinople roughly a generation later, who names the ringleader as a man in minor orders, a churchman on the bishop’s staff, and who says the crime disgraced not only the bishop but the whole Alexandrian church. And then there is the one fact that governs everything else written about her since, whether built on top of it or in spite of it: not one word she wrote survives. Her three known books are lost. What we have is a sentence of her father’s attached to her name, seven letters written to her by a student who loved her, one paragraph by a Christian historian who was ashamed, and a scattering of later notices. The woman herself has to be read out of other people’s handwriting.

(●) c. 355 AD: Born in Alexandria to Theon, the last scholar the Museum ever put on record. + Nobody wrote down the year she was born. The two dates you will meet in books are both worked out rather than reported, and they sit fifteen years apart. The older guess, made in the nineteenth century, puts her birth around 370 and makes her a woman of about forty-five when she died. The other comes from a sixth-century chronicler, John Malalas, who describes the victim of 415 as an old woman; working back from that gives roughly 355, and most recent scholarship has followed it. So the "c." on the front of her dates is doing real work, and it is doing it alone. The 415 at the other end is fixed to the month. Her father Theon was a mathematician and astronomer, and the Suda, a Byzantine encyclopedia compiled around the tenth century out of older sources, calls him the man from the Museum. The Museum, the Mouseion, was the research institute the Ptolemies had founded next to the famous library, where salaried scholars were fed at public expense and expected to do nothing but study. By Theon’s day it was a shadow of that, and he is the last member of it anyone names. He dated his own work by the sky: his commentary on Ptolemy records the solar eclipse he watched at Alexandria on 16 June 364 and the lunar eclipse of that November. That was the house she grew up in. Her mother is never mentioned. A girl in a family like that would have learned to read Homer and to handle a set of astronomical tables at about the same age, and the evidence is that she learned both extremely well.

(●) c. 380s AD: She took over her father’s subjects and then went past him. + The clearest statement of what she became comes from a Christian historian who never sat in her lecture room and had his own quarrel with the church that killed her. Philostorgius was an Arian, which is to say he belonged to the party that held the Son to be the Father’s first and greatest creature rather than God in the full sense, the party the councils had condemned. He wrote at Constantinople, and he says flatly that Theon educated his daughter in mathematics so well "that she far surpassed her teacher, and especially in astronomy, and taught many others the mathematical sciences" (Walford’s translation of the summary the patriarch Photius made of the lost original). The Suda, drawing on the pagan philosopher Damascius, says the same thing from the other side: she was not content with the mathematics her father taught her, so she took up the rest of philosophy as well. In late antiquity those were two different courses, and a student met them in order. Mathematics meant arithmetic, geometry, astronomy and harmonics, which is the mathematics of musical intervals, and those four were the subjects a beginner worked through first. Philosophy came after, and it meant Plato and Aristotle and the commentaries that had grown up around them. Hypatia ended up teaching the whole ladder, from the bottom rung to the top, and running what Socrates Scholasticus simply calls the school of Plato and Plotinus. Plotinus was the philosopher of the third century who had reworked Plato into the form late antiquity actually taught. One small thing survives that shows the two of them working side by side. Theon’s commentary on the third book of Ptolemy’s great astronomical treatise, the Almagest, carries a heading that says the edition was gone over by "the philosopher, my daughter Hypatia." Scholars argue about how much that means, whether she checked the copy or reworked the argument. Either way it is the one place in all of ancient literature where her name sits on a text that still exists.

(●) 391 AD: The Serapeum came down, and the city learned what its own crowds could do. + The Serapeum was the temple of Serapis, the god the Ptolemies had invented to hold Greeks and Egyptians together, and it stood on the high ground of the city like a citadel. In 391, after a street fight between pagans and Christians in which pagans had barricaded themselves inside, the bishop Theophilus obtained an imperial order and the building was pulled apart. Christian writers described it as a victory. The pagan historian Eunapius described it as the end of the world. Hypatia appears nowhere in any account of it. She was in her thirties, she was teaching in the city, and not one source places her in the temple, in the riot, or in the negotiations. If a philosopher stood at the centre of it, it was not her: the man who led the pagans inside the Serapeum was named Olympius. That distinction has not survived the retelling. A great deal of later writing runs the Serapeum and Hypatia together into a single story about the church burning down learning, and the sources will not carry it. What the year did give her was an education in her own city. Alexandria had a long habit of settling arguments in the street, and the habit ran in every direction: the city had killed bishops of its own, as the Suda points out, naming George and Proterius. So Hypatia knew what the place was. Twenty-four years before she was dragged out of her carriage, she watched a crowd in that city take a stone building apart with its hands.

(●) c. 393 AD: A young Libyan named Synesius came to her lecture room, and never got over it. + Synesius of Cyrene was a landowner’s son from the province next door, sent to Alexandria in his early twenties to be finished off intellectually. He stayed two or three years, and for the rest of his life he wrote to Hypatia as though the lecture room had never closed. Seven of his letters to her survive, and because his letters were collected and hers were not, they are the nearest thing we have to hearing her voice, in the way you can sometimes hear one end of a telephone call. They are not what a reader expects. One of them asks her to have a hydroscope made for him in brass and then describes the instrument, a graduated tube weighted at one end that floats upright in a liquid so you can read off its density from the notches. Another, written while the enemy was at his gates, tells her that he is breathing air tainted by the decay of dead bodies, and that for her sake alone he thinks he could bring himself to leave his own city. Another asks her to use her influence on behalf of two young men who have been stripped of their property, because his own influence is gone. Instruments, grief, and errands: that is what a student writes to a teacher he trusts. Synesius became a Christian bishop, of Ptolemais, in about 410. He had reservations about the job and said so in writing. What he never did, in any letter we have, is apologize for her or distance himself from her.

(●) 412 AD: Cyril became bishop, and two powers in Alexandria stopped speaking to each other. + When Theophilus died in 412 his nephew Cyril was installed on the third day, after his supporters and the supporters of the archdeacon Timothy had fought it out in the streets. Cyril would go on to become one of the most formidable theologians the church has produced, the man whose defense of the unity of Christ carried the Council of Ephesus. He was also, at thirty-something and newly installed, the head of an organization with money, crowds and no habit of restraint. The other power in the city was Orestes, the imperial prefect, which is to say the emperor’s governor for Egypt, and a baptized Christian himself. The quarrel between the two men ran through a string of ugly incidents that Socrates Scholasticus lays out one after another: a riot at the theatre; a schoolteacher named Hierax publicly tortured by the prefect; a night massacre of Christians; the expulsion of the entire Jewish community of Alexandria by Cyril and a mob; and then, down from the monastic desert of Nitria, five hundred monks who surrounded the prefect’s chariot and called him a pagan. One of them, a man named Ammonius, opened the prefect’s head with a stone. Orestes had him tortured to death. Cyril then collected the body, renamed the man Thaumasius, "the wonderful," and had him enrolled as a martyr. Socrates notes drily that the more sober-minded Christians would not go along with it, and that Cyril himself eventually let the matter drop. Hypatia was close to sixty, and Orestes was one of her friends. The Suda says the governors of Alexandria had a habit of attending her lectures. In a city where the bishop and the prefect were no longer on speaking terms, that friendship stopped being a private matter.

(●) March 415 AD: A Christian crowd pulled her from her carriage and killed her inside the cathedral. + The rumour went round the Christian population that Hypatia was the reason the prefect would not be reconciled to the bishop: that she was working on Orestes, and that while she lived there would be no peace. Socrates calls it what it was, a slander, and says the murder grew out of political jealousy rather than out of anything she taught. The ringleader he names is a reader called Peter. A reader, or lector, was a man in minor orders whose job was to read the Scriptures aloud in the liturgy: not a priest, but a member of the bishop’s staff, a churchman. He and others waited for her on the way home, dragged her from her carriage, and took her to the church called the Caesareum. That building had been begun by Cleopatra as a temple for Mark Antony and finished by Augustus, and by 415 it was the cathedral church of the city. There they stripped her and killed her with ostraka, a word that means potsherds and was also used of roof tiles. Then they tore the body apart, carried the pieces to a place called Cinaron, and burned them. It was Lent. What happened afterwards is thin. No one was tried, and the Suda says an imperial investigation was bought off. What did happen came from a long way away, and it came in the form of paperwork. In September of the following year the emperors issued a law about the parabalani, the bishop’s own corps of stretcher-bearers and attendants on the sick, enrolled by him and answerable to him. The law capped them at five hundred, barred them from public shows and from the council chamber and the courts, and put the enrolment of new men under the imperial prefect instead of the bishop. Sixteen months after that, in February of 418, the cap was raised to six hundred and the choosing went back to Cyril. The sources never say the parabalani killed her, and it would be wrong to say they did; but somebody in Constantinople clearly decided that the bishop of Alexandria had too many men.

(●) c. 439 AD: A Christian historian wrote it down, and called it a disgrace to the whole Alexandrian church. + Socrates Scholasticus was a lawyer in Constantinople who wrote a continuation of Eusebius’s church history. He brought the story down to the year 439 and finished within a few years of that, still within living memory of the murder, and he gave Hypatia a chapter of her own. He says she outstripped every philosopher of her own time, praises her dignity, records the slander that killed her, names the ringleader, describes the tiles, and then stops narrating and passes judgment. Set that beside the ordinary habits of ancient historians, who as a rule protected their own side and let an inconvenient episode go quiet. Socrates was a Christian writing church history for a Christian readership, and he could simply have left the chapter out. Instead he wrote that the affair brought no small disgrace on Cyril and on the whole Alexandrian church, and that nothing could be further from the spirit of Christianity than allowing things of that kind. Her school did not survive her. Her students scattered, and Alexandrian philosophy went quiet for a generation before reviving under other teachers. Her books were not copied, which in the ancient world is the same as being destroyed. The three titles the Suda records are all we have of her mind, and we have them the way we have the names of ships that sank.

What She Taught

(T1) Philosophy belongs in the open street, and to whoever will come and listen. + Picture a lecturer today walking to work in academic robes, the full medieval outfit, through ordinary traffic, and then teaching on the pavement to whoever stops. That is roughly what Damascius describes Hypatia doing. The tribon, the philosopher’s cloak, was a rough short garment that announced a trade the way a surgeon’s scrubs do, and it was a man’s garment. She put it on and walked through the middle of the city and expounded Plato or Aristotle in public. The alternative was the fashion of the day. Late antique philosophy had a strong pull toward the closed circle: initiation, ranked disciples, doctrines kept back from outsiders. Her own student Synesius wrote her a long complaint (Letter 154) about the men who had come to philosophy late in life and wore its solemn manner like a costume, the arched brows and the hand propping up the beard, and who "are even resolved to shackle us with a law which is altogether to their advantage; to wit, that no one shall be in open possession of any knowledge of the good." He set the quarrel before her and left the verdict with her, which tells you something about what she had taught him. Christian thought has its own version of this instinct and its own reasons for it. The gospel was preached in the open air from the beginning, on a hillside, in a boat, in the temple courts, and Paul argued in the market at Athens with whoever turned up (Acts 17:17). The parallel is not accidental. Both traditions held that the most important things are true for everyone, and a truth for everyone cannot be kept behind a door.

(Q) "Putting on the philosopher’s cloak although a woman and advancing through the middle of the city, she explained publicly to those who wished to hear either Plato or Aristotle or any other of the philosophers." + Source: the Suda, upsilon 166, drawing on Damascius, Life of Isidore (Suda On Line translation). Damascius was a pagan philosopher of the century after her, and the passage comes from the life he wrote of his own teacher Isidore, the book from which the encyclopedia took its long account of her. He is a hostile witness to the city that killed her and a friendly one to her.

(T2) The way up to what is eternal runs through number, and a student who will not do the mathematics is not ready. + There is a story that Plato had a line carved over the door of his school: let no one ignorant of geometry enter. Whether or not he did, the school Hypatia inherited worked that way, and the reason was not that mathematics is useful. It was that mathematics is the one subject where a person handles something unchanging. A drawn triangle smudges; the triangle itself does not. Learn to think about the second and you have begun to use the part of yourself that can think about God. So her teaching ran through the hard technical texts. The Suda credits her with commentaries on three of them. One was on Diophantus, whose Arithmetica is a collection of problems in what we would now call algebra. One was on the Conics of Apollonius, the treatise that worked out the curves you get by slicing a cone, the ellipse and the parabola and the hyperbola, eighteen hundred years before anyone found planets moving along them. And one was on the Astronomical Canon, almost certainly Ptolemy’s Handy Tables, the reference tables an astronomer used to compute where a planet would be on a given night. None of this was chalk on a board. Her students went away able to build things. Synesius wrote to her for a hydroscope, a weighted floating tube for measuring the density of a liquid, and his description in that letter is the earliest we have of the instrument. He also had a silver astrolabe made as a gift for a man of rank at Constantinople, a flattened map of the heavens on a disc, and in the covering essay he says openly whose help went into the design.

(Q) "It is a work of my own devising, including all that she, my most reverend teacher, helped to contribute, and it was executed by the best hand to be found in our country in the art of the silversmiths." + Source: Synesius of Cyrene, On the Gift of an Astrolabe (De dono astrolabii), in the passage presenting the finished instrument (FitzGerald translation). The essay goes to Paeonius, a man of standing at Constantinople, and Synesius is careful in front of that audience to say where the knowledge came from (T2).

(T3) A teacher’s real work is her students, and her lecture room was open to pagan and Christian alike. + Alexandria in her lifetime was not a place where the two religions mixed easily. Temples were being closed, bishops were being appointed with imperial backing behind them, and a pagan philosopher with any instinct for self-preservation had every reason to keep Christians at arm’s length. Hypatia did the opposite, and she did it in the one room she controlled. Consider who was sitting in it. Synesius was a Christian and ended up a bishop, and in one of the last letters he wrote her he sends his greetings on through the rest of the circle, "father Theotecnus and brother Athanasius," the household words a group of students used of one another. Socrates says her hearers came from a distance to study with her. The Suda says the city’s magistrates attended, and the magistrate she saw most of at the end, the prefect Orestes, was a baptized Christian. What held that room together was not a shared creed. It was a shared conviction that reason is worth following wherever it goes, and a shared affection for the woman teaching. Synesius’s letters to her are not the letters of a man humouring an old teacher. They are the letters of a man in trouble writing to the person he trusts most: he asks her to look after two ruined young men because he no longer can; he tells her, with his sons dead and his old influence gone, that she and virtue are the only good things left to him unspoiled; and at the very end he dictates a greeting to her from his bed. Christians have often had to decide what to do with a teacher outside the faith who is better than they are at the thing being taught. The church’s long answer, worked out by Justin and Clement and Augustine, is that all truth is God’s truth wherever it is found, and that a Christian may take gold out of Egypt. Synesius did not have to argue his way to that conclusion. He had sat in the room.

(Q) "I am dictating this letter to you from my bed, but may you receive it in good health, mother, sister, teacher, and withal benefactress, and whatsoever is honored in name and deed." + Source: Synesius of Cyrene, Letter 16, to Hypatia (FitzGerald translation). One of the last letters he wrote. He was bishop of Ptolemais by then, his sons had died, and he was dying himself. "Withal" is the old word for "besides," and the piling up of names is a man reaching for a word that will cover what she had been to him and not finding one (T3).

(T4) A philosopher owes the city her presence, not her withdrawal. + The safest course for a pagan intellectual in 410 was to be inconspicuous. Hypatia was not. Socrates says she appeared in public before the magistrates and was not embarrassed to walk into a room full of men, and he puts it down to parrhesia, the dignified frankness her education had given her, the freedom of somebody who can say what she thinks to a man with power over her. He adds that men admired her the more for her sophrosyne, a Greek word that covers self-command, good sense and modesty all at once, the settled poise of somebody who is not performing. That poise had a use. When Synesius needed help for two young men who had lost everything, Nicaeus and Philolaus, he wrote to her, not to a court official, and asked her to get them support "from all your friends, whether private individuals or magistrates" (Letter 81). Just before the request comes a line that shows how he understood what she was doing with her position: "You always have power, and long may you have it and make good use of that power." She was, in effect, a place where petitioners could go. There is a hard edge to all of this, and the end of her story turns on it. A philosopher who stays visible in a divided city becomes a factor in its politics whether she wants to be one or not. Orestes was her friend, Orestes was at war with the bishop, and the crowd concluded that the woman advising the prefect was the obstacle. The conclusion was false and the crowd was murderous, and the fact remains that she was killed for being in public life rather than for anything she believed.

(Q) "On account of the self-possession and ease of manner, which she had acquired in consequence of the cultivation of her mind, she not unfrequently appeared in public in presence of the magistrates. Neither did she feel abashed in coming to an assembly of men." + Source: Socrates Scholasticus, Ecclesiastical History VII.15 (Zenos translation, in the Nicene and Post-Nicene Fathers series). The sentence directly before this one says she had succeeded to the school of Plato and Plotinus and that students came from a distance to hear her. The sentence directly after says that all men admired her the more for her dignity and virtue.

(Q) "This affair brought not the least opprobrium, not only upon Cyril, but also upon the whole Alexandrian church. And surely nothing can be farther from the spirit of Christianity than the allowance of massacres, fights, and transactions of that sort." + Source: Socrates Scholasticus, Ecclesiastical History VII.15 (Zenos translation). "Not the least opprobrium" is nineteenth-century English for the opposite of what it sounds like to a modern ear: it means no small disgrace, a very great disgrace. This is the verdict of a Christian historian on his own church, written within a generation, and every later Christian account of Hypatia has had to begin from it.

What Christian Thinkers Made of Her

(†) The record of the crime survives because Christians kept it, and one of them named it as sin. + Everything a reader knows about the murder comes through Christian hands. Socrates Scholasticus, a lawyer and a layman of the Nicene church in Constantinople, wrote the chapter that supplies the ringleader’s name and the place and the month, and wrote it against his own side. Philostorgius, an Arian, recorded the killing in a sentence that lays it on the Homoousians, the party of Nicaea who confessed the Son to be of one substance with the Father: one Christian faction scoring against another, and thereby confirming the event from an independent direction. The Suda preserves the pagan Damascius. And late in the seventh century John of Nikiu, a bishop of the Coptic church, the Christianity of native Egypt, retold the whole business with enthusiasm, calling Hypatia a sorceress and praising the mob’s leader as a perfect believer in Jesus Christ. Those four leave a Christian reader with nowhere to hide and nothing much to argue about. The event is multiply attested, the victim was unarmed and old, the place was a church, and the season was Lent, the forty days the church sets aside for repentance. John of Nikiu is the warning: a Christian with a pen can bless a lynching and think he is defending the faith. The right response is the one Socrates already gave, which is to say plainly that this was murder and that murder is not open to a follower of Christ. "With it we bless our Lord and Father, and with it we curse people who are made in the likeness of God" (James 3:9). Whether Cyril ordered the death is the one question the sources genuinely divide on. Damascius says he plotted it out of envy, Malalas says the Alexandrians acted with their bishop’s leave, and Socrates, much the closest of the three, says only that the affair disgraced him; the historians who have worked through it mostly stop short of the charge. What the record shows without any argument is a bishop who had spent two and a half years teaching his city that its enemies could be handled by crowds, and a crowd that learned the lesson.

(†) Her Christian students never disowned her, and the best of them died calling her his teacher. + Synesius is the whole case, and he is enough. He studied under a pagan philosopher, he was made bishop of Ptolemais, and he went on writing to her as mother and teacher and benefactress until he died, probably a year or two before she was killed. He did not treat his philosophy and his office as two lives to be kept apart. He treated the first as the training that made him fit for the second. There is a name for what the church thinks is happening in a case like that. Theologians call it general revelation: the knowledge of God that is genuinely available to anyone through the created world, the conscience, and the reason, as distinct from the special revelation given in Scripture and in Christ. Paul appeals to it standing in Athens, quoting Greek poets back to Greeks (Acts 17:22-31), and again in writing when he says that Gentiles without the law "show that the work of the law is written on their hearts" (Romans 2:15). On that account a Hypatia is not an embarrassment to Christian faith. She is an example of how far an honest mind gets, and of how much a Christian can learn from one. The older Alexandrian tradition had already said so. Clement of Alexandria, teaching in the same city two centuries earlier, wrote that philosophy had been given to the Greeks as a tutor to bring them to Christ, in the way the law had been given to the Hebrews (Stromateis I.5). That was the settled Alexandrian instinct about pagan learning. What happened in 415 was the city betraying its own best habit.

(†) The legend she became is mostly not about her, and the truth is bad enough without it. + From the eighteenth century onward Hypatia became a useful weapon. John Toland published a pamphlet in 1720 setting her death against the clergy; Voltaire took her up; Gibbon gave the murder a memorable paragraph and laid it at Cyril’s door; Charles Kingsley wrote a popular novel in 1853 with a quarrel about High Church Anglicanism buried inside it; and in 1980 she reached a much wider audience through a chapter of Carl Sagan’s Cosmos, and a wider one still through a feature film in 2009. Along the way she acquired a set of details the ancient sources do not have. - She was not young. The girl of the paintings and the film comes from the novel. Damascius does call her beautiful, but the one ancient writer who comments on her age calls her an old woman. - She did not die with the Library of Alexandria. The great Ptolemaic library had been gone for centuries, and when the Serapeum that once held a daughter collection was pulled down in 391, no ancient account of that day mentions books at all. It happened twenty-four years before her death, and no ancient source connects her to it. - She was not killed for doing science. Socrates, the nearest witness, says the cause was political jealousy over her friendship with the prefect, and says the charge against her was a slander. The Suda adds envy of her wisdom, astronomy above all, which is envy of her standing and not an objection to her results. Nobody in the ancient record disputes her astronomy, her father’s trade was not illegal, and her students included churchmen. - Her death did not end ancient learning. Philosophy carried on in Alexandria for another two centuries, and the city produced Christian and pagan commentators of the first rank after her, John Philoponus among them. Cutting the legend away does not soften anything. A Christian mob murdered an elderly woman in a church during Lent because she was a friend of the wrong official, and a reader in minor orders led them. That is the charge the church actually has to answer, and the reason to strip off the additions is that they let the real one go unnoticed.

(†) Where the gospel parts company with her: a God who is spoken to rather than ascended to, and a way up that is not a curriculum. + An honest account of her philosophy has to begin with an admission, and it is a large one. Her books are lost, she wrote no creed, and the differences that follow are drawn from the school she taught in and from what her students carried away, not from sentences of hers. Socrates calls it the school of Plato and Plotinus; her pupil Synesius wrote hymns and essays full of it. That is the tradition called Neoplatonism, the late form of Platonism worked out by Plotinus in the third century, and these are its divisions from the gospel. - The One and the Father. At the summit of the Neoplatonist world stands the One, a source so far above everything that strictly speaking nothing can be said of it, not even that it thinks. Everything else overflows from it the way light comes off a lamp, without choice and without a beginning. The God of Scripture is not a source of that kind. He decides, he speaks, he is heard, and the world begins because he says so (Genesis 1:3; John 1:3). - Ascent and descent. The Platonist way up is a climb, and it comes in stages: purification first, then mathematics, then dialectic, which is the disciplined back-and-forth of argument that tests a definition until it holds, and at the summit contemplation. It is a curriculum, and a curriculum for the few with the leisure and the aptitude to attempt it. The gospel runs the other direction. "And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth" (John 1:14). God comes down, and he comes down to people who would have failed the entrance examination: "not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth" (1 Corinthians 1:26). - The body. For the Platonist the body is the soul’s descent into matter, and salvation means getting free of it. Scripture promises the opposite: not escape from the body but its resurrection. When Paul reached that point in Athens, some of his audience mocked him (Acts 17:32), and the mockery marks the exact place where the two accounts of a human being separate. - Knowing God. Contemplation as Plotinus describes it is a solitary achievement, the alone reaching the Alone. Christian faith is a relationship begun from the other side, and its language is address rather than attainment. None of this was the reason she died, and that bears saying twice, because the legend keeps turning it the other way round. Hypatia was killed by a rumour about a quarrel between two officials, not by a disagreement about the One. Her murderers had no interest in her metaphysics and almost certainly could not have stated it. That ledger is where an honest Christian reader disagrees with her, and the ledger of 415 is a different one altogether, in the church’s handwriting, and much worse.
