The Exiled Stoic Who Taught Epictetus

Musonius teaching
Be prepared to laugh. Musonius could be severe and hilarious in the same breath—a combination that made him one of antiquity’s most admired teachers.

By Dr Neel Burton — Psychiatrist, philosopher, and wine writer; Fellow of Green Templeton College, University of Oxford; author of over twenty books.

If Stoicism has a forgotten hero, it is Musonius Rufus.

Today, the names of Seneca, Epictetus, and Marcus Aurelius are familiar to millions. But in antiquity, many regarded Musonius as the greatest Stoic teacher of them all. His lectures attracted students from across the Roman world, foremost among them Epictetus.

Unlike Seneca, Musonius wrote no polished essays. His philosophy was not intended for libraries but for life. He taught in public, argued fearlessly, endured repeated exile, and demonstrated by his example that philosophy is not something merely to discuss, but something to live.

For Musonius, philosophy was not an escape from ordinary life but a preparation for it. It taught people how to eat, work, marry, raise children, endure hardship, and come to terms with death. His school, he liked to say, was not some concert hall, where people came to be amused and entertained, but a hospital, where they came, in trepidation, to be treated.

Yet there was nothing gloomy about him. Though uncompromising in his principles, he possessed a wonderfully dry wit. When a man with a long beard claimed to be a philosopher, Musonius replied that he could see the beard—but not the philosopher.

Beginnings

Gaius Musonius Rufus (c. 25–c. 100 CE) was born in Etruria into a family of Roman equestrians.

As a young man, he went about inquiring into the health of people’s souls, suggesting that his sympathies then lay more with the Cynics than with the Stoics.

He later established himself in Rome as one of the most celebrated Stoic teachers of the age.

When, in 60 CE, the paranoid Nero banished Rubellius Plautus, a Stoic and distant cousin of Nero, Musonius followed his friend to Asia Minor (modern-day Turkey) and only returned to Rome after Plautus’ death in 62.

Second and Third Exiles

When, in 65, Nero learnt of the Pisonian conspiracy, led by the senator Gaius Calpurnius Piso, to have him overthrown, he condemned nineteen people to death, including Seneca. Though not involved in the plot, Musonius was banished to the barren island of Gyaros, the Alcatraz of the Mediterranean.

Exile, however, seemed to weigh lightly upon him, even on Gyaros, and one of his surviving lectures is entitled, Why Exile Is Not an Evil.

Exile, he says, does not deprive us of water, earth, air, or the sun and stars. Nor does it deprive us of human companionship. But by removing us from luxurious living, it can cure our bodies and souls of many ills.

More significantly, exile does not prevent us from caring for our real needs and acquiring virtue. On the contrary, it provides us with more leisure in which to study and do good deeds.

Resourceful people are resourceful wherever they find themselves. Those who lack resourcefulness have vice, and not exile, to blame for their miseries. Ergo, it is vice, and not exile, that we should fear.

Musonius returned to Rome in 68, in the reign of Galba. In 70, in the reign of Vespasian, he accused and obtained the conviction of Egnatius Celer, who, despite calling himself a Stoic, had colluded with Nero in condemning the Stoic Barea Soranius and his daughter Servilia to death.

When, in 71, Vespasian banished all philosophers from Rome, his reputation rode so high that he was tolerated to remain—before being banished all the same into his third and longest exile, this time in Syria.

He returned to Rome in 79, in the reign of Titus, and died around 100 CE.

The Teacher of Philosophy

Musonius exerted an important influence on his two most famous pupils, Epictetus and the polymath Dio Chrysostom (‘Dio the Golden-Mouthed’).

To separate the wheat from the chaff, he would often turn would-be students away, explaining to the young Epictetus that ‘the more one pushes the intelligent person away from the life he was born for, the more he inclines towards it.’

His school, he insisted, was no place for clever performances. People came not to be entertained but to be cured. Because treatment can sometimes be painful, students might expect to suffer a bit. He measured the success of his lectures not by the applause that they received but by the shock and silence that they provoked.

He quoted Homer after Odysseus had related the length of his labours:

Thus he spoke, and they all stayed softly in silence,
And they were held by a magic spell in the shadowy hall.

Epictetus records Musonius saying:

Am I to sit down and tell you clever slogans and sayings so that you praise me as you leave, even though the shoulder is no better than it was, the head still hurts, and the abscess and fistula remain? Do young men leave home for these reasons and leave behind their parents, friends, kinfolk, and property so that they may yell ‘hooray’ when you utter witticisms? Did Socrates do this, or Zeno, or Cleanthes?

Musonius could be severe. By Epictetus’ own account, he once rebuked him for overlooking the omission in a syllogism (formal logical argument). Epictetus sought to excuse himself, saying, ‘It’s not like I burnt down the Capitol’—to which Musonius replied, ‘Idiot, the omission here is the Capitol.’

Nothing worthwhile, he insisted, is acquired without pain. But if we think that the path of virtue is too arduous, let us consider the alternatives and how much more trouble people put up with for the sake of gain or how many ills they suffer for the sake of fame, even though these things are worthless.

Practical Philosophy

Insofar as we know, Musonius did not work on anything for publication. However, two of his students wrote down his sayings and opinions. The Discourses, collected by a certain Lucius, form the basis of the 21 short lectures preserved in Stobaeus. But a second work, by one Pollio, has been lost except for fragments.

All in all, there remain 31 fragments (preserved in Stobaeus, Epictetus, and Aulus Gellius), as well as the 21 lectures, which altogether fit comfortably within 80 or so pages.

Musonius’ lectures are full of practical, everyday advice aimed at instilling virtue and include a lecture on home furnishings and even a lecture on hair. Men, he advised, ought to grow a beard on the grounds that the beard is the mark of manhood, on a par with a cock’s comb or a lion’s mane.

Besides facial hair, Musonius advocated a vegetarian diet (preferably raw and unprepared), plain clothing, and shelter of a kind that offers little more than the protection afforded by a cave.

He once gave a thousand sesterces to a man claiming to be a philosopher. When his friends protested that the fellow was a charlatan, he let him keep the not-inconsiderable sum, explaining that money was exactly what he deserved.

To do philosophy, said Musonius, is to reason correctly, and to reason correctly is to act correctly. The person who does philosophy thereby takes care of his country, family, and friends—in a word, everybody.

The person who does not do philosophy, even if he be a doctor, lawyer, or some such, is thoughtless, and thoughtlessness is very near to insanity.

Even if one rules only oneself, no one is more kingly than a philosopher or more fit to rule, because one cannot rule others unless one first rules oneself.

Musonius was not merely a teacher of Stoicism. He showed what a Stoic looked like.

The Slave Who Inspired an Emperor

Epictetus the slave and Marcus Aurelius the emperor
Epictetus inspired not one but two of Rome’s greatest emperors: Hadrian and Marcus Aurelius

By Dr Neel Burton — Psychiatrist, philosopher, and wine writer; Fellow of Green Templeton College, University of Oxford; author of over twenty books.

A biography of the Roman slave who rose into one of the leading Stoic philosophers, inspired an emperor, and shaped modern psychotherapy.

Stoic philosophy has exerted a profound influence on the history of ideas, inspiring thinkers as diverse as Descartes, Spinoza, Leibniz, Schopenhauer, Adam Smith, and J. S. Mill.

Its influence extends far beyond philosophy. In the field of mental health, Stoicism inspired what has become the most widely practised form of talking treatment, cognitive behavioural therapy (CBT). Aaron Beck (d. 2021), the father of CBT, wrote that ‘the philosophical origins of cognitive therapy can be traced back to the Stoic philosophers.’

Epictetus, together with Seneca, Marcus Aurelius, and Musonius Rufus, is one of our principal sources on Stoicism. But whereas Marcus Aurelius ruled the greatest empire on earth, and Seneca rose into the wealthiest man in that empire, Epictetus began as a slave.

Yet his teachings came to shape an emperor, influence Christian and Islamic thought, inspire the founders of modern psychotherapy, and guide millions in the face of hardship and adversity.

So, how did a mere slave achieve all this?

Life as a Slave

Epictetus (c. 50–c. 135 CE) was born into slavery at Hierapolis, in Asia Minor (modern-day Turkey). His name, in Greek, means something like ‘Acquired One’.

He spent his youth in Rome as a slave to Epaphroditus, a wealthy freedman and secretary to Nero. In 68, Epaphroditus assisted Nero in committing suicide (since Nero could not bring himself to plunge the dagger), with the deluded emperor lamenting, Qualis artifex pereo [‘What an artist dies in me!’].

In those early years, Epictetus, though a slave, discovered philosophy, and even managed to study under the charismatic Stoic Musonius Rufus. Musonius taught that philosophy is not merely something to be discussed but something to be lived—a lesson that Epictetus never forgot.

It is also around this time that he developed a disability, which may have owed to rheumatoid arthritis, although the Christian theologian Origen claims that it was his master who injured him.

One day, according to a famous anecdote, Epaphroditus lost his temper and grabbed Epictetus by the leg. He twisted it so forcefully that Epictetus warned him that it would break. When it snapped, Epictetus did not wince or cry, but calmly said, ‘Did I not tell you that it would break?’

Some time after Nero’s death, by virtue of his education or the dignity which it conferred upon him, Epictetus gained his civil freedom, having already acquired the far greater freedom of the mind.

Now a freedman, he taught philosophy in Rome.

Exile and the School at Nicopolis

When, in 94, Domitian banished all philosophers from the capital, Epictetus settled in Nicopolis, in Epirus, Greece, where he established a school and remained for the rest of his life.

Students travelled from across the Roman Empire to hear him speak. Among them was the young Arrian of Nicomedia, whose notes would preserve Epictetus’ teachings for posterity.

Like Musonius, Epictetus concentrated on ethics, arguing that physics and logic—the other two branches of ancient philosophy—ought to be in the service of practical action:

What do I care if matter is made up of atoms, indivisibles, or fire and earth? Isn’t it enough to know the nature of good and evil, the limits of desire and aversion, and of choice and refusal…?

The purpose of philosophy, he argued, is not to speculate about the stars but to learn how to live, ‘to practise how to remove from one’s life sighs and sorrow, grief and disappointment, and cries of “Alas!” and “Poor me!”’ This is largely a matter of according our will to the world, ‘so that nothing happens contrary to our wishes, and, conversely, nothing fails to happen that we want to happen.’

Hadrian, the future emperor, held Epictetus in the highest regard, and visited him, a former slave, in Nicopolis.

Epictetus’ Lamp

Epictetus did not marry or have children, despite urging these things upon others.

When he rebuked his friend and student Demonax for not marrying, Demonax sarcastically replied, ‘Very well, then, will you give me one of your daughters for a wife?’

However, in his retirement, Epictetus did, out of necessity, adopt the infant child of a friend, and raised him with the help of a woman.

His own needs remained remarkably modest. One day, the iron lamp by which he wrote was stolen. Reasoning that one can lose only what one has, he replaced it with a lamp of clay—which, after his death, was purchased at a great price by an admirer with no sense of irony.

The Discourses and Encheiridion

Epictetus wrote nothing himself. His teachings were recorded as the Discourses (or Diatribai) by his pupil Arrian of Nicomedia, also known for his account of the campaigns of Alexander the Great, written in a very different style.

In a prefatory note, Arrian writes: ‘Whatever I used to hear him say I wrote down, word for word, as best I could…’

He also claims that the Discourses ‘have somehow, without my knowledge or intention, fallen into the public’s hands.’

Such, in any case, is the public story. It is possible that Epictetus wrote the rather polished Discourses himself, with Arrian’s claimed authorship serving as a literary device to create an impression of spontaneity.

Whatever their precise origin, the Discourses remain unique in ancient philosophy. Rather than polished treatises, they preserve the atmosphere of a living classroom, with Epictetus questioning, teasing, rebuking… and constantly bringing philosophy back to the business of living.

Of the original eight books, only four have come down to us, and we also have the more portable Encheiridion, which is a digest of the Discourses—the word encheiridion [Greek, en+ kheir, literally, ‘in hand’]meaning something like ‘to have at hand’, originally with reference to a dagger or knife.

From Emperors to Modern Psychology

According to Origen, by the third century Epictetus’ renown exceeded that of Plato:

Plato is only found in the hands of those reputed to be philologists. By contrast, Epictetus is admired by ordinary people who have the desire to be benefited and who perceive improvement from his writings.

His influence spread far beyond the pagan world. In the ninth century, al-Kindi, the ‘Father of Arab Philosophy’, wrote a Device for Dispelling Sorrows which appears to have been influenced by Stoicism—for instance, in the contention that sorrow arises from thwarted desire, or that it is more a matter of convention than of nature.

In a striking analogy, which also features in the Encheiridion, al-Kindi compares life to a landfall during a much longer sea voyage back to our homeland, and warns us, as Epictetus did, not to get so caught up by the fruits and flowers as to forget about the ship.

Epictetus also left a lasting mark on modern psychology. In the first major work on rational emotive behaviour therapy (REBT), the forerunner of cognitive behavioural therapy (CBT), Albert Ellis (d. 2007) framed his project with a line from the Encheiridion: ‘Men are disturbed not by things, but by the views which they take of them.’

The US fighter pilot James Stockdale (d. 2005) credited Epictetus with helping him survive more than seven years of imprisonment and torture in Vietnam, including four years in solitary confinement in a 3′ by 9′ concrete, windowless cell.

When his A-4 Skyhawk was shot down over North Vietnam, Stockdale remembered thinking to himself as he parachuted towards the jungle: ‘I’m leaving the world of technology and entering the world of Epictetus!’

How the Son of a Court Physician Became the Most Influential Philosopher in History

Plato and Aristotle. Detail from the School of Athens by Raphael.
In Raphael’s School of Athens (1509–1511), Plato holds his Timaeus and points towards the heavens; Aristotle holds his Ethics and gestures towards the world before him.

By Dr Neel Burton — Psychiatrist, philosopher, and wine writer; Fellow of Green Templeton College, University of Oxford; author of over twenty books.

Few people have shaped the world as profoundly as Aristotle. Yet, for all his influence, surprisingly little is known about the man himself. As one historian remarked, all that can be said with certainty is that ‘the man was born, worked, and then died’. Even so, the surviving fragments reveal an extraordinary life, which transformed the son of a provincial court physician into the most influential philosopher in the West.

Aristotle was born in 384 BCE in Stageira, on the Chalcidice peninsula of north-eastern Greece. In 348, Philip II of Macedon occupied and destroyed the city, but then had it rebuilt and repopulated in honour of Aristotle, who had been his childhood friend and whom he had appointed to tutor his son, Alexander, the future King of the Oikouménē, or Known World. 

The Stagirite’s father, Nicomachus, served as physician to Philip’s father, Amyntas III of Macedon, and descended, purportedly, from the god of medicine, Asclepius—as did his mother, Phæstis. With the healing arts running so thickly in his blood, Aristotle would have been expected to follow in his father’s footsteps. Certainly, his medical background, and the empiricism of physicians such as Hippocrates, informed his method and philosophy. 

Aristotle had a brother and sister, and was probably the youngest of the three siblings. At about the age of thirteen, he lost both his parents and became the ward of Proxenus of Atarneus (in Æolis, Asia Minor), who rounded whatever medical training he had received from his late father. Proxenus married Aristotle’s sister, Arimneste. Together, they had a daughter, Hero, and a son, Nicanor. Hero in turn had a son, the historian Callisthenes of Olynthus, great nephew to Aristotle.

Plato’s Most Brilliant Student

In 367, Proxenus sent the seventeen-year-old Aristotle to study at Plato’s Academy, which had by then become a pre-eminent centre of learning. If Diogenes Laertius is to be believed, the grown-up Aristotle had small eyes and slender calves, dressed fashionably, and spoke with a lisp.

Aristotle remained at the Academy for nearly twenty years, only leaving after Plato’s death in 347. The reasons for his departure are unclear: he may have felt slighted at being passed over for the scholarchship of the Academy in favour of Plato’s nephew, Speussipus; or he may have fled, possibly even before Plato’s death, for fear of the growing anti-Macedonian feeling. In 351, the orator Demosthenes had delivered his First Philippic denouncing Philip II’s imperial ambitions, and in 348, the year before Plato’s death, Philip had razed Athenian ally Olynthus to the ground.

Twenty years at the Academy convinced Aristotle not only of philosophy’s power, but also of its limits. Where Plato sought truth by looking beyond the visible world, Aristotle increasingly sought it within it.

The Philosopher and the Tyrant

Then in his thirty-seventh year, Aristotle travelled with fellow Platonist Xenocrates of Chalcedon to Assos (in the Troad, Asia Minor) to join the court of Hermias of Atarneus, who had studied at the Academy. Aristotle may or may not have gone to Assos as an ambassador of Philip, who wished to have Hermias for an ally. In either case, it seems that he exerted a moderating influence on Hermias, who softened his harsh tyrannical rule—enabling him, in short succession, to win over neighbouring peoples and expand his territory.

In 344, Hermias was captured by a mercenary in the service of Artaxerxes III of Persia and tortured for information about the invasion plans of his ally Philip. But Hermias held his silence, his dying words being that he had done nothing shameful or unworthy of philosophy. Aristotle honoured the memory of his perfect friend with a statue at Delphi and a still extant hymn to virtue.

At around this time, he married Hermias’ niece and adoptive daughter, Pythias, who helped him in his work and bore him a daughter, also Pythias.

Paradise on Lesbos

After the death of Hermias, Aristotle and his student Tyrtamus crossed over to Lesbos to research the flora and fauna of the island and its remarkable lagoon, then known as the Pyrrha lagoon, now known as the Gulf of Kalloni.

Tyrtamus went down in history as Theophrastus [‘Divinely-speaking’], the nickname given to him by Aristotle. Supposedly, the more empirical Theophrastus concentrated on the flora while the more speculative Aristotle concentrated on the fauna, so that the one is remembered as the father of botany and the other as the father of zoology. In fact, Theophrastus also wrote on animals, and Aristotle on plants, but these works have been lost, as have almost all of Theophrastus’ wide-ranging works.

Aristotle was not simply doing biology for the sake of biology, but for the sake of philosophy. Like Plato, he was searching for universals, but this time from the ground up. ‘We should’ he said, ‘venture on the study of every kind of animal without distaste; for each and all will reveal to us something natural and something beautiful.’

Teaching Alexander

Aristotle spent no more than two years on Lesbos.

In 343, King Philip commissioned him to tutor his son Alexander, who was then around thirteen years old, promising in return to rebuild his native Stageira and repatriate its former citizens. In the Temple of the Nymphs at Mieza, near the Macedonian capital of Pela, Aristotle taught not only Alexander but also his close friend or lover Hephæstion, and two other future rulers, Ptolemy and Cassander.

It is said that Aristotle prepared for Alexander an annotated copy of the Iliad, which inspired the prince to model his life on that of the demy-divine Achilles. Even if the story is invented, Aristotle’s influence over Alexander is indicated by the crowd of zoologists and botanists that accompanied him on his Eastern conquests, and by the official chronicler of these conquests, who was none other than Aristotle’s great nephew, Callisthenes of Olynthus.

According to both Plutarch and Aulus Gellius, upon hearing that Aristotle had published some of his teachings, Alexander wrote to him from Asia:

Alexander to Aristotle, greeting. You have not done well to publish your books of oral doctrine; for what is there now that we excel others in, if those things which we have been instructed in be laid open to all? For my part, I assure you, I had rather excel others in the knowledge of what is excellent, than in the extent of my power and dominion. Farewell.

Later, as pharaoh in Egypt, Ptolemy built the Great Library of Alexandria, turning the city, which had been founded by Alexander, into a major centre of learning. Alexander, and Ptolemy after him, did much to disseminate Greek culture, so that three centuries later Greek seemed like the natural choice of language for the New Testament.

Aristotle’s Great Project: Organising All Human Knowledge

In around 339, Speussipus suffered a stroke and died, and Xenocrates became the third scholarch of the Academy, with Aristotle passed over for a second time. Among those who frequented the lectures of Xenocrates at the Academy were Zeno of Citium, founder of the Stoic school, and Epicurus of Samos, founder of the Epicurean school.

In 334, Aristotle, now returned to Athens, established his own school in a public exercise and training ground dedicated to the god Apollo Lyceus [‘Apollo the Wolf-god’], whence its name, the Lyceum. A temple had once stood on the expansive site, which in Aristotle’s time had different areas dedicated to different purposes. Both Socrates and Plato had spoken or taught there, to the extent that the Lyceum is the setting of Plato’s Euthydemus, which features Socrates and Cleinias, the grandson of Alcibiades, in conversation with Euthydemus and Dionysodorus, a pair of moronic brothers and sophists.

Aristotle taught in the morning, and in the afternoon would sometimes give a public lecture. He often did his thinking and teaching while walking along the Lyceum’s shaded paths, or peripatoi, so that his students, who doubled up as his colleagues and researchers, came to be known as the peripatetics.

Over the next twelve years, Aristotle wrote many of his works and collected the West’s first great library, including copies of the constitutions of 158 cities. He also developed the world’s first botanical garden and zoological park from the plant and animal specimens that Alexander kept returning from the East.

After the death of his wife Pythias, he became involved with Herpyllis of Stageira, who bore him a son whom he named Nicomachus after his father. To this son, he dedicated his major work of ethics, the Nicomachean Ethics. According to the Suda, he also had an eromenos [younger male lover], the historian Palæphatus of Abydus.

Aristotle’s school lived or limped on until 86 BCE, when Athens was sacked by Sulla, the only man in history to have occupied both Athens and Rome. According to Plutarch, Sulla felled the ancient planes of the Academy and Lyceum to build siege engines. In antiquity, the Lyceum had stood to the east of the city wall. In 1996, its remains were uncovered in a park behind the Hellenic Parliament, while clearing space for the new Museum of Modern Art.

Exile and Death

In the East, Callisthenes had become increasingly critical of Alexander’s adoption of Persian customs, especially those, such as proskynesis (falling down before the king and kissing the ground or his feet), which fed into his mounting megalomania.

When a former pupil implicated Callisthenes in a regicidal plot, Alexander left Aristotle’s great nephew to perish in prison. According to Diogenes Laertius, Callisthenes was ‘confined in an iron cage and carried about until he became infested with vermin through lack of proper attention; and finally he was thrown to a lion and so met his end.’ The death of his great nephew soured Aristotle’s relationship with Alexander, and prompted Theophrastus to write a treatise on grief, the now lost Callisthenes.

Even so, Aristotle’s long-time association with Alexander had led the Athenians to perceive him as Macedonian. After Alexander’s death in Babylon in 323, anti-Macedonian feeling in Athens flared up, and Demophilius and Eurymedon the Hierophant charged Aristotle with impiety, possibly for praying to his late friend Hermias rather than anything in the Physics or Metaphysics. Aristotle fled to the solitude, or loneliness, of his country house at Chalcis in Eubœa, an island off the Attic coast and the homeland of his mother’s family. Referencing the trial and execution of Socrates, he explained, ‘I will not allow the Athenians to sin twice against philosophy.’

In the event, Aristotle died within the year, in 322, aged sixty-two, possibly from an abdominal condition. Theophrastus, who was not Macedonian but Lesbian, had remained in Athens as scholarch of the peripatetic school. In his will, Aristotle named him as his successor and bequeathed him his works and library. On the family side, he left a furnished house, three female slaves, and a talent of silver to his wife or concubine Herpyllis, and appointed his nephew Nicanor as guardian to the still young Nicomachus. Nicomachus became a pupil of Theophrastus and, according to Aristippus, his eromenos. He died in battle while still young.

Theophrastus inherited not only Aristotle’s school but also the intellectual legacy of the man who, for centuries to come, would simply be known as ‘The Philosopher’.

Did Stoicism Make Marcus Aurelius a Better Emperor?

Marcus Aurelius writing the Meditations
Marcus Aurelius wrote the Meditations as a private journal, never intending it to be published.

By Dr Neel Burton — Psychiatrist, philosopher, and wine writer; Fellow of Green Templeton College, University of Oxford; author of over twenty books.

Essay substantially revised on 28 July 2026.

In Plato’s Republic (c. 375 BCE), Socrates says that his vision of the ideal state could not exist ‘until philosophers are kings, or the kings and princes of this world have the spirit and power of philosophy…’

Here he was at last, more than five hundred years later, rarer even than the Æthiopian phœnix: the fabled philosopher-king—and not just any vassal or kinglet, but the Emperor of Rome.

His private journal, the Meditations, has become one of the world’s most widely read works of philosophy, inspiring everyone from statesmen and soldiers to psychologists and countless ordinary readers seeking wisdom in difficult times. J. S. Mill, in On Liberty (1859), hailed it as ‘the highest ethical product of the ancient mind’.

So, how did it work out?

How Marcus Became Emperor

Marcus was born in 121 CE as Marcus Annius Verus, into a prominent senatorial family with intimate imperial ties. He began from an early age to evince signs of virtue, so that the emperor Hadrian noticed him and even punned on his name, Verus (‘True’), calling him Verissimus (‘The Truest’).

In 136, Hadrian, having no male heir, adopted Lucius Ceionius Commodus, who now became Lucius Aelius Caesar. But Lucius died in 138, and Hadrian had to choose again.

This time, Hadrian adopted Titus Aurelius Antoninus, the husband of Marcus’ aunt Faustina the Elder, on condition that Antoninus in turn adopt Marcus and the son of the late Lucius, also Lucius.

The intricacy of these machinations suggests that Hadrian intended Antoninus as a simple placeholder for Marcus, and the much younger Lucius as a spare.

Whatever the case, by the age of 17, Marcus had already been marked out as a future emperor.

Childhood and Education

Whereas most would have been overjoyed, Marcus was not.

In 132, under the influence of Diognetus, the eleven-year-old Marcus had taken up the dress and habits of a philosopher—to the extent that his mother had had to talk him out of sleeping on the floor. In the Meditations, the grown-up Marcus thanks Diognetus, a Stoic and painter, for introducing him to ‘the Greek lifestyle—the camp-bed and the cloak.’

His other tutors came to include the lawyer and orator Marcus Cornelius Fronto, the rhetorician Herodes Atticus, and Plutarch’s grandson, Sextus of Chaeronea.

As an orator, Fronto was second only to Cicero, and had something of the Cicero about him when he purchased the fabled Gardens of Maecenas. Much of the extensive and years-long correspondence between Marcus and Fronto is still with us.

Herodes Atticus, one of the richest men in the empire, funded several public works including, in Athens, the Panathenaic Stadium and the odeon known as the Herodeon, both of which, remarkably, are still in use.

But although Marcus had for tutors the greatest men of his age, it is the dog-eared copy of Epictetus that he received from the Stoic Junius Rusticus that made the greatest impression upon him. Still today, it is difficult to read the Meditations without hearing the echo of Epictetus—the former slave who inspired an emperor. 

Marriage and Children

In 136, Marcus had been betrothed to the daughter of Lucius Aelius Caesar.

But after the death of Hadrian, the engagement was annulled, and Antoninus, the new emperor, betrothed him to his daughter Faustina (even though Marcus and Faustina were legally brother and sister).

Marcus married Faustina seven years later, in 145, while serving out his second term as consul.

After the birth of their first child, a daughter, in 147, Antoninus gave Marcus the imperium and the tribunicia potestas(tribunician power), thereby elevating him, in effect, to the rank of junior emperor.

Faustina the Younger would bear Marcus at least thirteen more children, including two sets of twins, over the next 23 years—but only four daughters and one unfortunate son, Commodus, outlived their parents. In the Meditations, Marcus likens his children to leaves, and echoes Homer in the Iliad: ‘Men come and go as leaves year by year upon the trees. Those of autumn the wind sheds upon the ground, but when the spring returns the forest buds forth with fresh vines.’

Relationship with His Co-Emperor

As Antoninus began to age and ail, Marcus took over more of his responsibilities—so that he was already well worn in upon his accession to the imperial throne in 161.

He could easily have ruled alone, but instead insisted upon making his adoptive brother Lucius co-emperor.

In truth, Marcus would rather have remained a philosopher, or private citizen, but considered it his Stoic duty to take up the purple. In the Meditations, he compares philosophy and the court to a mother and stepmother: ‘you would pay your respects to your stepmother, yes… but it’s your real mother you’d go home to. The court… and philosophy. Keep returning to it, to rest in its embrace. It’s all that makes the court—and you—endurable.’

In practice, Lucius—now Lucius Verus—deferred to Marcus, who was ten years older and, by experience and temperament, better suited to the role.

The burden Marcus inherited could scarcely have been greater. Rome stretched from Britain to Mesopotamia, embracing perhaps a quarter of the world’s population. Every frontier demanded vigilance, every province justice, every crisis a solution. Marcus found himself ruling the greatest empire on earth just as it entered one of the most turbulent periods in its history.

The Antonine Plague

Towards the end of 161, the Tiber broke its banks and flooded much of Rome, bringing about a famine.

At around the same time, the Parthians invaded the client state of Armenia and began destabilizing the East.

Lucius nominally led the Roman response from Antioch, assisted by able generals such as the Assyrian Roman, Gaius Avidius Cassius.

As the war wore on, Lucius made a trip to Ephesus to wed Marcus’ daughter Lucilla.

The Romans prevailed, but the returning armies brought back a plague, possibly of smallpox. The so-called Antonine Plague raged throughout the empire for many years and quite literally decimated (killed one in every ten) the population.

The Marcomannic Wars

In 167 or 168, Marcus and Lucius set out on a punitive expedition across the Rhine and Danube, while a horde of German tribes invaded Italy from behind their backs.

In 169, Lucius suddenly died, perhaps of a stroke, or from the plague.

Marcus battled on for three more years to secure the north-eastern border, while other parts of the empire suffered smaller scale rebellions or invasions. It is at around this time that he kept the notebook which we now know as The Meditations.

He never intended these notes for publication. They were not a philosophical treatise but a private conversation with himself: reminders to remain patient, humble, just, and rational amid war, illness, political intrigue, and personal grief. Their very privacy adds to their enduring appeal. We encounter Marcus not as a distant emperor addressing his subjects, but as a fellow human being struggling, day after day, to become a better person.

Threat to His Throne

By 175, Avidius Cassius had taken control of the East, including Egypt, the granary of Rome.

In that year, he heard rumours of Marcus’ death and proclaimed himself emperor.

Marcus set off for the East, rejecting offers of assistance from some of the friendlier German tribes. But three months after his proclamation, Cassius was murdered by one of his own centurions.

His head was sent to Marcus, but the philosopher-king refused to behold it, and pardoned Cassius’ co-conspirators in the Senate.

Eastern Tour

Marcus then felt obliged to shore up the East, visiting Antioch, Alexandria, and Athens, where he was initiated into the Eleusinian Mysteries.

In Athens, he endowed the first ever public chairs, one for each of the four major schools of philosophy, the Platonic, Peripatetic (Aristotelian), Stoic, and Epicurean.

His beloved Faustina, who had come with him, died in Cappadocia, and he honoured her service by having her deified.

Death and Succession

In 177, Marcus proclaimed his 16-year-old son Commodus co-emperor, breaking with the Nerva-Antonine dynasty’s remarkably successful practice of succession by the best man available—a tradition which, in truth, owed more to necessity than to enlightened principle.

This, with the benefit of hindsight, or even without, was a grave error, but what else could Marcus have done short of planting the seed of a civil war, or ordering the assassination of his own son?

In 180, Marcus, who had been sickly all his life, possibly with a stomach ulcer, passed away at his military headquarters in Sirmium, Pannonia, thereby bringing to an end the long period of relative peace and prosperity now known as the Pax Romana (27 BCE—180 CE).

In 192, Commodus was strangled in the bath by his wrestling partner Narcissus, acting in concert with other palace insiders, and with the retrospective approval of the Senate.

The demise of Commodus brought the Nerva-Antonine dynasty to a close, to be followed by the chaotic Year of the Five Emperors.

Assessment

Marcus did not merely write about Stoicism but sought to govern an empire according to its principles. Faced with flood, famine, plague, invasion, rebellion, bereavement, and chronic ill health, he repeatedly chose duty over inclination, clemency over retribution, and self-command over self-glorification. If any ruler came close to Plato’s ideal of the philosopher-king, it was Marcus Aurelius.

I’ll leave the last word on Marcus to the historian Cassius Dio, who lived through his entire reign:

[Marcus Aurelius] did not meet with the good fortune that he deserved, for he was not strong in body and was involved in a multitude of troubles throughout practically his entire reign. But for my part, I admire him all the more for this very reason, that amid unusual and extraordinary difficulties he both survived himself and preserved the empire. Just one thing prevented him from being completely happy, namely, that after rearing and educating his son in the best possible way he was vastly disappointed in him. This matter must be our next topic; for our history now descends from a kingdom of gold to one of iron and rust, as affairs did for the Romans of that day.
