The Twelve Caesars
On the Life of the Caesars[1], in Latin De vita Caesarum, or as it is often known in English, The Twelve Caesars, is a set of twelve biographies of Julius Caesar and the first 11 emperors of the Roman Empire. On the Life of the Caesars, which was written in 121 during the reign of the emperor Hadrian, was the most popular work of Hadrian's personal secretary, Suetonius, and is the largest among his surviving writings. It was dedicated to a friend, the Praetorian prefect Gaius Septicius Clarus, in 119. On the Life of the Caesars was considered very significant in antiquity and remains a main source on Roman history. The book discusses the significant and critical period of the Principate from the end of the Republic to the reign of Domitian; comparisons are often made with Tacitus whose surviving works document a similar period.
Critical approaches: Reliability
Suetonius used the imperial archives to research eyewitness accounts, information, and other evidence to produce the book. He also quotes from Gaius Asinius Pollio, Cremutius Cordus and the Acts of Augustus.
However, critics say the book is founded on gossip and citations of historians who had lived in the time of the early emperors, rather than on primary sources of that time. The book can be described as very racy, packed with gossip, dramatic and sometimes amusing. There are times the author subjectively expresses his opinion and knowledge.
Though he was never a senator, Suetonius took the side of the Senate in most conflicts with the princeps, as well as the senators' views of the emperor. This resulted in biases, both conscious and unconscious. Suetonius lost access to the official archives shortly after beginning his work. He was forced to rely on second-hand accounts when it came to Claudius (with the exception of Augustus' letters which had been gathered earlier) and does not quote the emperor.
Despite this, it provides valuable information on the heritage, personal habits, physical appearance, lives and political careers of the first Roman Emperors. It mentions details that other sources do not. For example, Suetonius is the main source on the life of Caligula, his uncle Claudius, and the heritage of Vespasian (the relevant sections of the Annals by his friend and contemporary Tacitus being lost). Suetonius made a reference in this work to "Chrestus", which may refer to "Christ". During the book on Nero, Suetonius mentions a sect known as the Christians (see Historicity of Jesus). Like many of his contemporaries, Suetonius took omens seriously and carefully includes reports of omens portending Imperial births, accessions and deaths.
Influence on later literature
Lives of the Caesars served as a model for the biographies of 2nd century emperors compiled by Marius Maximus. This collection, apparently entitled Caesares, does not survive, but it was a source for a later biographical collection, known as Historia Augusta, which now forms a kind of sequel to Suetonius' Lives of the Caesars. The Historia Augusta is a collective biography, partly fictionalized, of Roman emperors and usurpers of the second and third centuries.
In the ninth century Einhard modelled himself on Suetonius in writing the Life of Charlemagne, even borrowing phrases from Suetonius' physical description of Augustus in his own description of the character and appearance of Charlemagne. Robert Graves names The Twelve Caesars as one of his major sources for I Claudius and Claudius the God (later dramatized by the BBC). Graves also made a widely read translation of The Twelve Caesars, first published in Penguin Classics in 1957.
Constituent works
Life of Julius Caesar
The first few chapters of this section are missing. Suetonius begins this section by describing Caesar's conquests, especially in Gaul and his Civil War against Pompey the Great. Several times Suetonius quotes Caesar. Suetonius includes Caesar's famous decree, "Veni, vidi, vici" (I came, I saw, I conquered). In discussing Caesar's war against Pompey the Great, Suetonius quotes Caesar during a battle that Caesar nearly lost, "That man (Pompey) does not know how to win a war."
Suetonius describes an incident that would become one of the most memorable of the entire book. Caesar was captured by pirates in the Mediterranean Sea. Caesar engaged in debate and in philosophical discussion with the pirates while in captivity. He also promised that one day he would find them and crucify them (this was the standard punishment for piracy during this time). When told by the pirates that he would be held for a ransom of 20 talents of gold, Caesar laughed, and said that he must be worth at least 50 talents. Just as he had promised, after being released, Caesar captured the pirates and crucified them.
It is from Suetonius that we first learn of another incident during the life of Julius Caesar. While serving as governor in Hispania, Caesar once visited a statue of Alexander the Great. Upon viewing this statue, Suetonius reports that Caesar fell to his knees, weeping. When asked what was wrong, Caesar sighed, and said that by the time Alexander was his (Caesar's) age, Alexander had conquered the whole world.
Suetonius describes Caesar's gift at winning the loyalty and admiration of his soldiers. Suetonius mentions Caesar commonly referring to them as "comrades" instead of "soldiers." When one of Caesar's legions took heavy losses in a battle, Caesar vowed not to trim his beard or hair until he had avenged the deaths of his soldiers. Suetonius describes an incident during a naval battle. One of Caesar's soldiers had his hand cut off. Despite the injury, this soldier still managed to board an enemy ship and subdue its crew. Suetonius mentions Caesar's famous crossing of the Rubicon River, (the border between Italy and Cisalpine Gaul), on his way to Rome to start a Civil War against Pompey and ultimately seize power.
Suetonius later describes Caesar's major reforms upon defeating Pompey and seizing power. One such reform was the modification of the Roman calendar. The calendar at the time had already used the same system of solar years and lunar months that our current calendar uses. Caesar updated the calendar so as to minimize the number of lost days due to the prior calendar’s imprecision regarding the exact amount of time in a solar year. Caesar also renamed the fifth month (also the month of his birth) in the Roman calendar July, in his honor (Roman months started in March, not January as they do under the current calendar). Suetonius says that Caesar had planned on invading and conquering the Parthian Empire. These plans were not carried out due to Caesar's assassination.
Suetonius then includes a description of Caesar's appearance and personality. Suetonius says that Caesar was semi-bald. Due to embarrassment regarding his premature baldness, Caesar combed his hair over and forward so as to hide this baldness. Caesar wore a senator's tunic with an orange belt. Caesar is described as routinely wearing loose clothes. Suetonius quotes the Roman dictator Lucius Cornelius Sulla as saying, "Beware the boy with the loose clothes, for one day he will mean the ruin of the Republic." This quote referred to Caesar, as Caesar had been a young man during Sulla's Social War and subsequent dictatorship. Suetonius describes Caesar as taking steps so that others would not refer to him as king. Political enemies at the time had claimed that Caesar wanted to bring back the much reviled Roman Kingdom.
Finally, Suetonius describes Caesar's assassination. Shortly before his assassination, Caesar told a friend that he wanted to die a sudden and spectacular death. Suetonius believes that several omens predicted the assassination. One such omen was a vivid dream Caesar had the night before his assassination.
The day of the assassination, Suetonius claims that Caesar was given a document describing the entire plot. Caesar took the document, but did not have a chance to read it before he was assassinated.
Suetonius says that upon being stabbed, Caesar reproached the conspirator Brutus, asking "And you, my child?" This specific wording varies slightly from the more famous quote, "Even you, Brutus?" from William Shakespeare’s play "Julius Caesar."
Life of Augustus
Before he died, Julius Caesar had designated his great nephew, Gaius Octavius (who would be named Augustus by the Roman Senate after becoming emperor) as his adopted son and heir. Octavius' mother, Atia, was the daughter of Caesar's sister, Julia Caesaris.
Octavian (who had not yet been named Augustus by the Roman Senate) finished the civil wars started by his great-uncle, Julius Caesar. One by one, Augustus defeated the legions of the other generals who wanted to succeed Julius Caesar as the master of the Roman world. Suetonius includes descriptions of these civil wars, including the final one against Mark Antony that ended with the Battle of Actium. Antony had been Octavian's last surviving rival, but committed suicide after his defeat at Actium. It was after this victory in 31 BC that Octavian became master of the Roman world and imperator (or emperor). His declaration of the end of the Civil Wars that had started under Julius Caesar marked the historic beginning of the Roman Empire, and the Pax Romana. Octavian at this point was given the title "Augustus" (meaning "the venerable") by the Roman Senate.
After describing the military campaigns of Augustus, Suetonius describes his personal life. A large section of the entire book is devoted to this. This is partly because after Actium, the reign of Augustus was mostly peaceful. It has also been noted by several sources that the entire work of "The Twelve Caesars" delves more deeply into personal details and gossip relative to other contemporary Roman histories.
Suetonius describes a conflicted relationship between Augustus and his daughter, Julia. Augustus had originally wanted Julia, his only child, to provide for him a male heir. Due to difficulties regarding an heir, and Julia's promiscuity, Augustus banished Julia to an island and considered having her executed. Suetonius quotes Augustus as repeatedly cursing his enemies by saying that they should have "a wife and children like mine."
According to Suetonius, Augustus lived a modest life, with few of the luxuries that his rank would have allowed him to have. Augustus lived in an ordinary Roman house, ate ordinary Roman meals, and slept in an ordinary Roman bed.
Suetonius describes certain omens and dreams that predicted the birth of Augustus. One dream described in the book suggested that his mother, Atia, was a virgin impregnated by a Roman God. In 63 BC, during the Consulship of Cicero, several Roman Senators dreamt that a king would be born, and would rescue the Republic. 63 BC was also the year Augustus was born. One other omen described by Suetonius suggests that Julius Caesar decided to make Augustus his heir after seeing an omen while serving as the Roman Governor of Hispania Ulterior.
Suetonius includes a section regarding the only two military defeats Rome suffered under Augustus. Both of these defeats occurred in Germany. The first defeat was inconsequential. During the second, the Battle of Teutoburg Forest, three Roman Legions (Legio XVII, Legio XVIII, and Legio XIX) were slaughtered by Germanic barbarians due to poor planning by the Roman General Publius Quinctilius Varus. Much of what is known about this battle was written in this book. According to Suetonius, this battle "almost wrecked the empire." It is from Suetonius where we get the reaction of Augustus upon learning of the defeat. Suetonius writes that Augustus hit his head against a wall in despair, repeating, Quintili Vare, legiones redde! ('Quinctilius Varus, give me back my legions!') This defeat was one of the worst Rome suffered during the entire Principate. The result was the establishment of the rivers Rhine and Danube as the natural northern border of the Roman Empire. Rome would never again push its territory deeper into Germany. Suetonius suggests that Augustus never fully got over this defeat.
Life of Tiberius
Suetonius describes the early career of Tiberius, which included his command of several Roman armies in Germany. It was his leadership in these German campaigns that convinced Augustus to adopt Tiberius and to make him his heir. According to Suetonius, Tiberius retired at a young age to Rhodes, before returning to Rome upon the death of Augustus. The ascendance of Tiberius to the throne was possible because the two grandsons that Augustus had died before Augustus, and the last grandson, Postumus Agrippa, although originally designated co-rule with Tiberius was later deemed morally unsound by Augustus.
Augustus began a long (and at times successful) tradition of adopting an heir, rather than allowing a son to succeed an emperor. Suetonius quotes from the will Augustus left. Suetonius suggests that not only was Tiberius not thought of highly by Augustus, but Augustus expected Tiberius to fail.
After briefly mentioning some successes, Suetonius goes into depth regarding the madness of Tiberius. Tiberius would not only have homosexual sex (which was not unusual in the ancient world), but he would also have sex with boys. The extent was considered, even by Roman standards, to be extreme. Although Suetonius doesn't suggest it, other historians have suggested that Tiberius may have had sex with his successor Caligula when he was very young. Tiberius was very cruel to his subjects. He would arbitrarily have people executed. Offenses as innocent as speaking ill of Augustus were punishable by death. He would crush the heads of children with his bare hands. Suetonius describes Tiberius once forcing a subject to drink large quantities of wine. He then had the subject's genitals tied so tightly that he could not urinate.
Tiberius died of natural causes. Suetonius describes widespread joy in Rome upon his death. There was a desire to have his body thrown off a particular cliff and into the Tiber River, as this he had done many times previously to others. Tiberius had no living children and no living heir when he died. However, he did have an adopted grandson, Gaius Caesar Caligula.
Life of Caligula
Most of what is known about the reign of Caligula comes from Suetonius. Caligula was so hated upon his death, in the upper classes it is to be noted, that the Roman Senate issued a decree that all records of him be destroyed. In addition, other contemporary Roman works, such as those of Tacitus, contain little, if anything, about Caligula. Therefore, most of what existed at some point regarding his reign was lost long ago.
Suetonius refers to Caligula as Gaius during most of the work, his true name; Caligula being the name given to him by his father's soldiers: 'little boots', as he would often dress in miniature battle gear and 'drill' (as he knew not the commands, but the troops loved him all the same though, and pretended to understand him) the troops at a young age. Caligula's father, Germanicus, was loved throughout Rome as a brilliant military commander and example of Roman pietas. Tiberius had adopted Germanicus as his heir, with the hope that Germanicus would succeed him. Germanicus ended up dying before he could succeed Tiberius.
Upon the death of Tiberius, Caligula became emperor. Initially the Romans loved Caligula due to their memory of his father. But most of what Suetonius says of Caligula is negative. Suetonius says that Caligula was worse than Tiberius. Modern historians have speculated that he may have had anything from Schizophrenia to Encephalitis. Suetonius describes Caligula as having an affliction that caused him to suddenly fall unconscious. Suetonius believed that Caligula knew that something was wrong with him.
Suetonius cited examples of Caligula's insanity, whose supposed 'infamy' lives to this day, however there is evidence to support the logic behind a rival theory, that he based himself as some sort of romano-greco ruler, almost an equivalent to the older meaning of 'tyrant'. Most, if not all, of the surviving examples of Caligula's madness come from Suetonius too. Caligula appointed his horse to the Senate, however again, it has been suggested that this was merely to insult the senators, as if to say his horse could do a better job than them. He married one of his sisters, although it is important to note that incest was rife in all areas of society at the time, and also had had sexual relations with multiple men, although it is important to note that only certain kinds of homosexual acts in much of Ancient Rome, and Ancient Greece too, were looked down upon, that would be being on the receiving end of homosexual anal intercourse as this was seen to 'put men upon the level of women', so it more of a sexist view than anything really. It is no wonder therefore that this time was seen as a 'corrupted one' compared to the earlier Republican era, where monogamy, faithfulness and honesty were qualities much more put into practice.
He tells also, that Caligula once sent an army to the northern coast of Gaul. As they prepared to invade Britain, one rumour had it that he had them pick sea shells on the shore, although this was probably a fabrication of one of his enemies back in Rome, the word for shell in Latin doubling as the word that the legionaries of the time used to call the 'huts' that the soldiers erected during the night while on campaign, and that he had no choice but to return as there was dissent among the Senate. He once built a walkway from his palace to a Pagan Temple, so that he could be closer to his "brother," the Roman God Jupiter, as he believed himself to be a deity, not uncommon among Roman emperors, although this bridge building adventure may have something to do with him almost being challenged to by a prophecy, or that he was imitating the 'apparently infamous' crossing of the Hellespont by Xerxes, prior to his invasion of Ancient Greece. He would also have busts of his head replace those on statues of different Gods.
He would call people to his palace in the middle of the night. When they arrived, he would hide and make strange noises. At other times, he would have people assassinated, and then call for them. When they did not show up, he would remark that they must have committed suicide, part of his apparent odd sense of humour, sadism some cried.
Suetonius describes several omens that predicted the assassination of Caligula. He mentions a bolt of lightning that struck Rome on the Ides of March, which was when Julius Caesar was assassinated. Lightning was an event of immense superstition in the ancient world. The day of the assassination, Caligula sacrificed a flamingo. During the sacrifice, blood splattered on his clothes. Suetonius also describes a comet that was seen shortly before the assassination. In the ancient world, comets were believed to foretell the death or assassination of important people. Suetonius even suggested that Caligula's name itself was a predictor of his assassination, noting that every Caesar named Gaius (such as the dictator Gaius Julius Caesar) had been assassinated.
Caligula was an avid fan of Gladiatorial combats. He was assassinated shortly after such a fight. Suetonius mentions two possible scenarios describing the exact events. The assassination plot had been put together by several angry subjects supposedly young, fanatical men intent upon restoring the Republic, states one theory. Although what we hear of Caligula of the plebs or commoners is all good, as he did provide a stable economy, and paid the legions in good time, important in keeping the peace and the borders safe of emboldened enemies, making the time a healthy, prosperous one for the lower class, save for the upper echelons of society and power, who were affected by his so called 'ravings'. Caligula was only the first of what would be many Roman Emperors who were to be assassinated.
Life of Claudius
Suetonius describes Claudius as the first emperor adopted into the Julian family. The previous emperors (Augustus, Tiberius, Caligula, as well as the earlier dictator Julius Caesar) had all been born into the Julian family,
The assassination of Caligula caused Claudius to become frightened. He hid behind some curtains, convinced that he would be murdered next. A soldier noticed his feet underneath the curtains and took him to a Praetorian camp, where he was declared emperor.
We learn from Suetonius that Claudius was the first Roman commander to invade Britain since Julius Caesar a century earlier. He also went farther than Caesar, and made Britain subject to Roman rule. Caesar had conquered Britain, but left the Britons alone to rule themselves. Claudius was not as kind. The invasion of Britain was the only major military campaign under his reign.
His madness was similar to that of Tiberius. Like Tiberius, he was not as cruel as Caligula. Suetonius discusses some of the cruelties that Claudius had been known for, although he does not devote as much attention to this as he did to Caligula's cruelty or even to that of Tiberius.
Suetonius discusses several omens that foretold the assassination of Claudius. He mentions a comet that several Romans had seen shortly before the assassination. As mentioned earlier, comets were believed to foretell the deaths of significant people. Upon hearing of this, Claudius ordered the execution of several Roman citizens, including Senators and aristocrats. Claudius was shortly after this the victim of an assassination conspiracy, dying of poison.
Suetonius paints Claudius as a ridiculous figure, belittling many of his acts and attributing the objectively good works to his retinue.[2] Thus the conception of Claudius as the weak fool, controlled by those he supposedly ruled, was preserved for the ages. Claudius’s dining habits figure in the biography, notably his immoderate greed and his affection for the city taverns, on which several other emperors attempted to impose tight regulations.
His personal and moral failings aside however, most modern historians agree that Claudius generally ruled well. They cite his military success in Britannia as well as his extensive public works. His reign came to an end when he was poisoned by a mushroom, probably by his last wife Agrippina in an attempt to have her own son from a previous marriage ascend the throne.
Life of Nero
Suetonius portrays the life of Nero in a similar fashion to that of Caligula—it begins with a recounting of how Nero assumed the throne ahead of Claudius' son Britannicus and then descends into a recounting of various atrocities the young emperor allegedly performed.
One characteristic of Nero that Suetonius describes was Nero's fascination with music. Suetonius describes Nero as being a gifted musician. Nero would often give great concerts with attendance compelled for upper class Romans. These concerts would last for hours on end, and some women were rumored to fake childbirth to escape them.
Nero's eccentricities continued in the tradition of his predecessors in mind and personal perversions. According to Seutonius, Nero had one boy castrated, and then had sex with him as though he were a woman. Suetonius quotes one Roman who lived around this time who remarked that the world would have been better off if Nero's father Gnaeus Domitius Ahenobarbus had married someone more like the castrated boy.
It is in Suetonius we find the beginnings of the legend that Nero "fiddled as Rome burned." Suetonius recounts how Nero, while watching Rome burn, exclaimed how beautiful it was, and sang an epic poem about the sack of Troy while playing the lyre.
Suetonius describes Nero's suicide, and remarks that his death meant the end of the reign of the Julio-Claudians (because Nero had no heir). According to Suetonius, Nero was condemned to die by the Senate. When Nero knew that soldiers had been dispatched by the senate to kill him, he committed suicide.
Life of Galba
The book about Galba is short. This is because Galba's reign was only several months long. Galba was the first emperor of the Year of the Four Emperors.
Galba was able to ascend to the throne because Nero's death meant the end of Julio-Claudian rule.
Suetonius includes a brief description of Galba's family history. Suetonius describes Galba as being of noble birth, and born into a noble patrician family. Suetonius also includes a brief list of omens regarding Galba and his assassination.
Most of this book describes Galba's ascension to the throne and his assassination, along with the usual side notes regarding his appearance and related omens. Suetonius does not spend much time describing either any accomplishments nor any failures of his reign.
According to Suetonius, Galba was killed by Otho's loyalists.
Life of Otho
His full name was Marcus Salvius Otho. Otho's reign was only a few months. Therefore, the book on Otho is short, much as the book on Galba had been.
Suetonius used a similar method to describe the life of Otho as he had used to describe the life of Galba. Suetonius describes Otho's family, and their history and nobility. And just as Suetonius had done with prior Caesars, he includes a list of omens regarding Otho's reign and assassination.
Suetonius spends most of the book describing the ascension of Otho, his assassination, and the other usual topics. Suetonius suggests that as soon as Otho ascended the throne, he started defending himself against competing claims to the throne.
According to Suetonius, Otho suffered a fate similar to the fate Galba had suffered. It was the loyalists of another aspiring emperor (in this case, the next emperor Vitellius) who wanted to kill him. Suetonius claims that one night Otho realized that he would soon be murdered. He contemplated suicide, but decided to sleep one more night before carrying out a suicide. That night he went to bed, with a dagger under his pillow. The next morning he woke up, and stabbed himself to death.
Life of Vitellius
In the book of the last of the short-lived emperors, Suetonius briefly describes the reign of Vitellius.
Suetonius says that it was the followers of Vitellius who had assassinated Otho.
This book gives an unfavorable picture of Vitellius; however it should be remembered that Suetonius' father was an army officer who had fought for Otho and against Vitellius at the first Battle of Bedriacum.
Suetonius includes a brief description of the family history of Vitellius, and related omens.
Suetonius finally describes the assassination of Vitellius. According to Suetonius, Vitellius was dragged naked by Roman subjects, tied to a post, and had animal waste thrown at him before he was killed. However, unlike the prior two emperors, it was not the next emperor who killed Vitellius. The next emperor and his followers had been waging a war against the Jews in Palestine at the time. The death of Vitellius and subsequent ascendance of his successor ended the worst year of the early principate.
Life of Vespasian
Suetonius begins by describing the humble antecedents of the founder of the Flavian dynasty a follows with a brief summary of his military and political career under Aulus Plautius Claudius and Nero and his suppression of the uprising in Judaea. Suetonius documents an early reputation for honesty but also a tendency toward avariciousness.
A detailed recounting of the omens and consultations with oracles follows which Suetonius suggests furthered Vespasian's imperial pretensions. Suetonius then briefly recounts the escalating military support for Vespasian and even more briefly the events in Italy and Egypt that culminated in his accession.
Suetonius presents Vespasian's early imperial actions, the reimposition of discipline on Rome and her provinces and the rebuilding and repair of Roman infrastructure damaged in the civil war, in a favourable light, describing him as 'modest and lenient' and drawing clear parallels with Augustus. Vespasian is further presented as being extraordinarily just and with a preference for clemency over revenge.
Suetonius describes avarice as Vespasian's only serious failing, documenting his tendency for inventive taxation and extortion. However, he mitigates this failing by suggesting that the emptiness of state coffers left Vespasian little choice. Moreover, intermixed with accounts of greed and 'stinginess' are accounts of generosity and lavish rewards. Finally Suetonius gives a brief account of Vespasian's physical appearance and penchant for comedy.
Having contracted a 'bowel complaint,' he tried to continue his duties as emperor from what would be his deathbed, but on a sudden attack of diarrhea he said "An emperor ought to die standing," and died while struggling to do so.
Life of Titus
Elder son of Vespasian, and second emperor of the Flavian dynasty. As Suetonius writes: "The delight and darling of the human race."
Life of Domitian
Younger brother of Titus, second son of Vespasian, and third emperor of the Flavian dynasty. Recorded as having gained the throne through deliberately letting his brother die of a fever. During Titus' rule he had caused dissent and had sought the throne through rebellion.
