Marcus Aurelius

Anyone asking who was Marcus Aurelius has to begin with a wealthy, well-connected household in Rome. He was born Marcus Annius Verus on April 26, 121 CE, into a senatorial family of Spanish origin that had already produced consuls. His father died when the boy was very young, probably around the age of three, and he was raised largely by his grandfather, also named Marcus Annius Verus, who held the consulship three times ^[1].

The emperor Hadrian noticed the boy early. He nicknamed him Verissimus, a play on his family name meaning "most truthful," and enrolled him in the equestrian order at age six, an unusually early honor ^[2]. Marcus received the education of a Roman aristocrat, tutored at home rather than in public schools. His teachers included the celebrated orator Marcus Cornelius Fronto, whose surviving correspondence with his pupil gives a rare, affectionate picture of the future emperor as a student: fond of his teachers, prone to overwork, and increasingly drawn to philosophy at the expense of rhetoric ^[3].

That pull toward philosophy began in adolescence. He adopted the rough cloak of a philosopher and took to sleeping on the floor until his mother, Domitia Lucilla, talked him out of it. The painter and Stoic teacher Diognetus, and later Junius Rusticus, introduced him to the discipline that would shape his adult mind. Rusticus in particular gave him the discourses of the former slave Epictetus, the single strongest philosophical influence on the Meditations ^[1].

Succession politics, not ambition, set the course of his career. In 138 CE the dying Hadrian adopted Antoninus Pius as his heir on the condition that Antoninus in turn adopt two boys: the seventeen-year-old Marcus and the young Lucius Verus, son of Hadrian's previously intended successor ^[2]. Marcus took the name Marcus Aelius Aurelius Verus and moved into the imperial household. He later wrote that he was reluctant to leave his mother's house for the palace.

Antoninus prepared him deliberately. Marcus held the consulship in 140, at eighteen, and again in 145, the year he married Antoninus's daughter Faustina the Younger ^[1]. He received the tribunician power and other imperial prerogatives in 147, making him in practice a junior colleague in government. For over two decades he worked at Antoninus's side, absorbing the routines of administration, law, and correspondence that filled an emperor's day. It was, by ancient standards, the longest and calmest apprenticeship any Roman ruler ever received ^[4].

When Antoninus died in March 161, the Senate offered Marcus sole power. He refused to accept it unless Lucius Verus was made co-emperor with him, honoring Hadrian's original arrangement. Rome thus gained, for the first time, two Augusti ruling jointly, though Marcus held the senior position of Pontifex Maximus and greater practical authority ^[2].

The calm ended almost at once. In the reign's first year the Tiber flooded Rome and Vologases IV of Parthia invaded Armenia, destroying a Roman legion and overrunning parts of Syria. Lucius Verus went east as nominal commander while capable generals, above all Avidius Cassius, fought the war. By 166 Roman forces had sacked the Parthian cities of Seleucia and Ctesiphon and restored the eastern frontier ^[1].

The returning army brought catastrophe with it. A pandemic, known as the Antonine Plague and thought by many modern scholars to have been smallpox, spread through the empire from 165 onward. Mortality estimates vary widely, but ancient writers describe emptied army camps and towns, and the physician Galen, who witnessed the outbreak, recorded its symptoms ^[5]. The plague thinned the legions just as pressure on the northern frontier reached its worst point in generations.

From the late 160s, Germanic and Sarmatian peoples, among them the Marcomanni, Quadi, and Iazyges, crossed the Danube. At one point invaders penetrated into northern Italy and besieged Aquileia, the first such incursion in nearly three centuries ^[4]. Marcus spent most of his remaining years on campaign along the Danube, in what are collectively called the Marcomannic Wars. Lucius Verus died in 169, probably of a stroke, leaving Marcus to rule and fight alone. To fund the wars without new taxes, he auctioned imperial palace treasures, including his wife's silk and gold garments ^[1].

Any honest list of Marcus Aurelius achievements starts with a book he never intended anyone to read. During the northern campaigns, writing in Greek in army camps along the Danube, he kept a private journal of self-examination and Stoic exercise. One early section is headed "Among the Quadi on the River Gran." The work, transmitted under the title Meditations (in Greek, Ta eis heauton, "to himself"), circulated after his death and has been read continuously since the Renaissance as a manual of practical ethics ^[6]. It remains the fullest surviving record of an ancient ruler's inner life.

His government left more conventional marks as well. Legal sources preserve a large body of his rulings, and historians have noted his attention to the status of vulnerable groups: he strengthened protections in guardianship law for orphans and minors and appointed a dedicated praetor for guardianship cases ^[2]. He treated the Senate with pointed respect, appearing at its sessions when in Rome and asking its formal approval for expenditures, gestures that earned him a lasting reputation for civility rare among emperors.

Military results were mixed but real. By the late 170s Roman arms had beaten the Marcomanni, Quadi, and Iazyges into treaties, and Cassius Dio reports that Marcus hoped to organize new provinces north of the Danube before his death cut the project short ^[4]. The wars are commemorated on the Column of Marcus Aurelius, which still stands in Rome's Piazza Colonna, its spiral reliefs including the famous "rain miracle" that saved a trapped Roman force. The gilded bronze equestrian statue of Marcus, preserved through the Middle Ages and now in the Capitoline Museums, survives as the only complete bronze equestrian statue of a Roman emperor ^[7].

Marcus and Faustina were married for thirty years, until her death in 175. The union was unusually fertile and unusually sad: the couple had at least thirteen children, and most died young ^[1]. Only one son, Commodus, born in 161, survived to adulthood, along with several daughters. Later gossip, preserved in the unreliable Historia Augusta, accused Faustina of infidelity, but Marcus's own words tell a different story. In the first book of the Meditations he thanks the gods for a wife "so obedient, so affectionate, so simple" ^[6].

His health was fragile for much of his life. He wrote to Fronto about chest pains and poor appetite, and Cassius Dio records that he ate sparingly and relied on the drug theriac, prescribed by his physician Galen, to manage chronic illness during the northern wars ^[4]. He was, by his own account, a man who had to work at equanimity rather than one to whom it came naturally.

One domestic detail from his early life became legend. Book One of the Meditations is a catalogue of debts: to his grandfather he owed good morals, to his mother piety and simple living, to his adoptive father Antoninus a long portrait of patient, unpretentious rule. Scholars treat the passage as one of the most personal documents to survive from antiquity, the emperor privately auditing his own upbringing ^[3].

In 175, while Marcus campaigned in the north, the general Avidius Cassius proclaimed himself emperor in the east, reportedly after false news of Marcus's death. Egypt and much of Syria recognized the usurper. Marcus prepared to march east, but within about three months Cassius was killed by his own officers, and the revolt collapsed ^[2]. Marcus refused to punish the senators who had corresponded with Cassius and asked that the rebel's papers be burned unread, an act ancient writers cited as proof of his clemency ^[4]. Faustina, who had accompanied the eastern journey, died late that year in a village in Cappadocia; Marcus had her deified and founded a charity for girls in her name.

He returned to Rome in 176 and celebrated a triumph, then in 177 raised the sixteen-year-old Commodus to the rank of co-emperor, settling the succession on his son rather than on an adopted heir. The decision broke with the adoptive pattern of the previous four reigns and has been debated ever since, though Marcus was the first emperor in nearly a century to have a legitimate son survive him ^[1].

War on the Danube resumed in 178, and father and son went north together. Marcus fell ill early in 180 and died on March 17 at or near Vindobona, the legionary base on the site of modern Vienna; some sources place his death at Sirmium ^[2]. He was fifty-eight. Cassius Dio, who lived through what followed, wrote that with his death the empire descended from a kingdom of gold to one of iron and rust ^[4].

The verdict of antiquity was quick and durable. Marcus was deified by the Senate, and later Romans looked back on him as a model ruler; the historian Herodian remarked that he proved his philosophy by his conduct rather than his words ^[4]. Edward Gibbon, in the eighteenth century, famously judged the period ending with Marcus's death the happiest and most prosperous age of the human race, an assessment that fixed the emperor's place in the modern imagination ^[2].

The Meditations gave him a second, larger afterlife. First printed in 1559, the book has been translated into dozens of languages and read by figures as different as Frederick the Great, John Stuart Mill, and Bill Clinton. Its core exercises, focusing on what lies within one's control, accepting mortality, and treating obstacles as material for virtue, made Marcus a central figure in the modern revival of Stoicism as practical self-help and in cognitive approaches to therapy ^[6]. Popular culture has kept his image current too, from the equestrian statue copied in city squares to fictionalized versions of his final days in films such as Gladiator.

Historians reading beyond the legend find a more complicated figure. Persecution of Christians occurred under his rule, including the executions at Lyon in 177, though scholars debate how far the emperor directed rather than merely tolerated local actions ^[1]. His choice of Commodus proved disastrous. Yet the basic Marcus Aurelius facts retain their force: a ruler with absolute power who spent his nights interrogating his own conduct, and who governed through plague, flood, revolt, and nearly continuous war without abandoning either the work or the examination. Few lives in any Marcus Aurelius biography ancient or modern offer so direct a view of a person trying, under maximum pressure, to be good ^[3].
