The history of Nero’s reign is problematic in that no historical sources survived that were contemporary with Nero. These first histories at one time did exist and were described as biased and fantastical, either overly critical or praising of Nero. The original sources were also said to contradict on a number of events. Nonetheless, these lost primary sources were the basis of surviving secondary and tertiary histories on Nero written by the next generations of historians. A few of the contemporary historians are known by name.
Fabius Rusticus, Cluvius Rufus and
Pliny the Elder all wrote condemning histories on Nero that are now lost. There were also pro-Nero histories, but it is unknown who wrote them or on what deeds Nero was praised.
The bulk of what is known of Nero comes from
Tacitus, Suetonius and
Cassius Dio, who were all of the Patrician class. Tacitus and Suetonius wrote their histories on Nero over fifty years after his death, while Cassius Dio wrote his history over 150 years after Nero’s death. These sources contradict on a number of events in Nero’s life including the death of
Claudius, the death of
Agrippina and the Roman fire of
64, but they are consistent in their condemnation of Nero.
A handful of other sources also add a limited and varying perspective on Nero. Few surviving sources paint Nero in a favorable light. Some sources, though, portray him as a competent emperor who was popular with the Roman people, especially in the east.
Constantine in the 4th century became a patron of Christianity. Christian influence in Rome continued from that time forward. In these circumstances, Nero's record of persecuting Christians reinforced the negative perceptions that already existed.
;Cassius Dio Cocceianus
Cassius Dio (
c. 155- 229) was the son of
Cassius Apronianus, a Roman senator. He passed the greater part of his life in public service. He was a senator under
Commodus and governor of Smyrna after the death of
Septimius Severus; and afterwards suffect consul around
205, as also proconsul in Africa and Pannonia.
Books 61–63 of Dio's
Roman History describe the reign of Nero. Only fragments of these books remain and what does remain was abridged and altered by
John Xiphilinus, an 11th century monk.
;Dio Chrysostom
Dio Chrysostom (
c. 40– 120), a Greek philosopher and historian, wrote the Roman people were very happy with Nero and would have allowed him to rule indefinitely. They longed for his rule once he was gone and embraced imposters when they appeared:
Indeed the truth about this has not come out even yet; for so far as the rest of his subjects were concerned, there was nothing to prevent his continuing to be Emperor for all time, seeing that even now everybody wishes he were still alive. And the great majority do believe that he still is, although in a certain sense he has died not once but often along with those who had been firmly convinced that he was still alive.<ref>Dio Chrysostom, Discourse XXI, On Beauty</ref>
;Epictetus
Epictetus (
c. 55- 135) was the slave to Nero's scribe
Epaphroditos. He makes a few passing negative comments on Nero's character in his work, but makes no remarks on the nature of his rule. He describes Nero as a spoiled, angry and unhappy man:
Is [prosperity and happiness] in royal power? It is not. If it were, Nero would have been happy.<ref>Epictetus, About Cynicism</ref>
Only see that he has not Nero's stamp. Is he passionate, is he full of resentment, is he fault-finding? If the whim seizes him, does he break the heads of those who come in his way?<ref>Epictetus,Against the Quarrelsome and Ferocious</ref>
;Josephus
The historian
Josephus (
c. 37- 100), while calling Nero a tyrant, was also the first to mention bias against Nero. Of other historians, he said:
But I omit any further discourse about these affairs; for there have been a great many who have composed the history of Nero; some of which have departed from the truth of facts out of favor, as having received benefits from him; while others, out of hatred to him, and the great ill-will which they bare him, have so impudently raved against him with their lies, that they justly deserve to be condemned. Nor do I wonder at such as have told lies of Nero, since they have not in their writings preserved the truth of history as to those facts that were earlier than his time, even when the actors could have no way incurred their hatred, since those writers lived a long time after them.<ref>Josephus, Antiquities of the Jews [[wikisource:The Antiquities of the Jews/Book XX#Chapter 8
;Marcus Annaeus Lucanus
Though more of a poet than historian,
Lucanus (
c. 39- 65) has one of the kindest accounts of Nero's rule. He writes of peace and prosperity under Nero in contrast to previous war and strife. Ironically, he was later involved in a conspiracy to overthrow Nero and was executed. He wrote:
Where Caesar sits, be evermore serene, And smile upon us with unclouded blue. Then may all men lay down their arms, and peace, Through all the nations reign, and shut the gates, That close the temple of the God of War.<ref>Marcus Annaeus Lucanus, Pharsalia (Civil War) (c. 65)</ref>
;Philostratus
Philostratus II "the Athenian" (
c. 172- 250) spoke of Nero in the
Life of Apollonius Tyana (Books 4–5). Though he has a generally negative view of Nero, he speaks of others' positive reception of Nero in the East.
;Pliny the Elder
The history of Nero by
Pliny the Elder (
c. 24- 79) did not survive. Still, there are several references to Nero in Pliny's
Natural Histories. Pliny has one of the worst opinions of Nero and calls him an "enemy of mankind."
;Plutarch
Plutarch (
c. 46- 127) mentions Nero indirectly in his account of the Life of Galba and the Life of Otho. Nero is portrayed as a tyrant, but those that replace him are not described as better.
;Seneca the Younger
It is not surprising that
Seneca (
c. 4 BC- 65), Nero's teacher and advisor, writes very well of Nero. He wrote:
So Nero shows his face to Rome before the people's eyes, His bright and shining countenance illumines all the air, While down upon his graceful neck fall rippling waves of hair. Thus Apollo. But Lachesis, quite as ready to cast a favourable eye on a handsome man, spins away by the handful, and bestows years and years upon Nero out of her own pocket. As for Claudius, they tell everybody to speed him on his way, With cries of joy and solemn litany.<ref>Seneca the Younger, Apocolocyntosis 4</ref>
;Suetonius Tranquillus
Suetonius (
c. 69- 130) was a member of the equestrian order and head of the department of the imperial correspondence. Removed by Hadrianus in 121, he started writing biographies of the emperors, accentuating the anecdotal and sensational aspects.
Portions of his biography of Nero appear openly hostile, and while it might be possible that Nero's rule invited such hostility, some modern historians question the accuracy of his account. For example, the following quote, often taken as a sign of Nero's insanity, might simply be propaganda:
He castrated the boy Sporus and actually tried to make a woman of him; and he married him with all the usual ceremonies, including a dowry and a bridal veil, took him to his home attended by a great throng, and treated him as his wife. And the witty jest that someone made is still current, that it would have been well for the world if Nero's father Domitius had that kind of wife. This Sporus, decked out with the finery of the empresses and riding in a litter, he took with him to the courts and marts of Greece, and later at Rome through the Street of the Images, fondly kissing him from time to time.<ref>Suetonius, The Lives of Twelve Caesars, Life of Nero 28</ref>
;Tacitus Publius Cornelius
The
Annals by
Tacitus (
c. 56- 117) is the most detailed and comprehesive history on the rule of Nero, despite being incomplete after the year
66. He is unkind to Nero, but unlike other historians, he minimizes the use of sensational stories. Tacitus described the rule of the Julio-Claudian emperors as generally unjust. He also thought that existing writing on them was unbalanced:
The histories of Tiberius, Caius, Claudius, and Nero, while they were in power, were falsified through terror, and after their death were written under the irritation of a recent hatred.<ref>Tacitus, Annals [[wikisource:The Annals (Tacitus)/Book 1#1
Tacitus was the son of a
procurator, who married into the elite family of Agricola. He entered his political life as a senator after Nero's death and, by Tacitus' own admission, owed much to Nero's rivals. Realizing that this bias may be apparent to others, Tacitus protests that his writing is true:
I would not deny that my elevation was begun by Vespasian, augmented by Titus, and still further advanced by Domitian; but those who profess inviolable truthfulness must speak of all without partiality and without hatred.<ref>Tacitus, History [[wikisource:The Histories (Tacitus)/Book 1#1
