The Six-Day Roman Fire of July 64 CE That Destroyed Ten of the City's Fourteen Districts and Was Almost Certainly Not Started by the Emperor

The Great Fire of Rome began on the night of 18-19 July 64 CE in the wooden merchant shops at the southeastern end of the Circus Maximus — the great chariot-racing stadium between the Palatine and Aventine hills. The shops were typical of late-Republican and early-Imperial Roman commercial buildings: timber-framed, multi-storey, packed close together, used for both retail and residential occupation. The combination of summer drought, tight wood-and-pitch construction, and the Roman urban density made the city catastrophically fire-prone.

The fire ran north and east along the Aventine and Palatine hills through the first night. By the morning of 19 July it had crossed into the southeastern districts. By 20 July it had reached the Forum Romanum. It burned for six days, was partially contained on 24 July 1871, then flared again from a new source on the Aemilian estate of Tigellinus the praetorian prefect and burned for three more days.

The damage assessment was specific. Of Rome’s 14 administrative districts (regiones), 3 were completely destroyed (the Aventine, the Caelian, and the area east of the Circus), 7 were severely damaged, and 4 were essentially untouched (the Transtiberim and the northern districts on the Quirinal and Esquiline). The Forum Romanum, the Capitoline temples, and several of the great Republican-era monuments were lost or badly damaged.

The death toll was not recorded by any surviving ancient source. The conventional modern estimate is several thousand, with homelessness — perhaps 200,000 of Rome’s 1 million population — through the autumn of 64.

Where Nero was

Nero was at his coastal villa at Antium — modern Anzio, about 50 km south of Rome — when the fire began. He had been there for the summer political season. The contemporary record (Tacitus, Annals 15.39) records that he returned to Rome as soon as he learned of the fire and personally organised emergency relief: opening the imperial gardens on the Vatican hill to the displaced, providing emergency food, importing grain from Ostia, and rebuilding the city through a post-fire urban-design programme that included wider streets, mandatory stone construction for ground floors, and public colonnades.

The Nero post-fire urban reconstruction is considered, by modern Roman historians, to be one of the more competent administrative responses by any Julio-Claudian emperor. The fact that he had been at Antium when the fire began, and that he had returned and organised the relief operation, is documented across all three of the main ancient sources — including the hostile Tacitean account.

The fiddling

The famous story that Nero “fiddled” — meaning, in the standard 16th-17th century English usage, played a lyre or sang — while Rome burned has three principal ancient sources, all hostile.

Tacitus (Annals 15.39), writing approximately 50 years after the fire, records the rumour without endorsing it. He says that “a rumour had spread that, while the city was burning, [Nero] had appeared on his domestic stage and sung the destruction of Troy, comparing the present evil to the calamity of ancient times.” Tacitus does not say the rumour is true. He says it spread.

Suetonius (Nero 38), writing approximately 50 years later than Tacitus, presents the same story more confidently, with Nero singing the Sack of Ilium from his Maecenas Tower as the city burned. Suetonius’s narrative voice is more hostile to Nero than Tacitus’s; the 21st-century historical consensus treats Suetonius’s flair for damaging anecdote as somewhat less reliable than Tacitus’s drier account.

Cassius Dio (62.18), writing approximately 130 years after the fire, presents the story as fact.

The physical evidence against the literal story is straightforward: Nero was at Antium when the fire began. He could not have been singing on a Roman tower at the moment of ignition because he was not in Rome. The most charitable reconstruction is that he sang a Sack of Ilium on his return to Rome on approximately 21 July as part of a public-relations performance — possibly to console the population, possibly out of poor judgement, possibly as part of a religious commemoration. The hostile retrospective reconstruction redated the performance to the early hours of the fire itself.

The Christian scapegoats

Public opinion in Rome blamed Nero personally for the fire by autumn 64. The rumours took two forms: that he had ordered the fire deliberately to clear ground for the new imperial palace complex that he had been planning for years (the Domus Aurea, eventually built on portions of the burned districts), or that the fire had been a political accident that he was insufficiently distressed by.

Nero identified a scapegoat: the small Christian community in Rome, then perhaps a few thousand members, which was already distrusted by the Roman public as a superstitious eastern religious sect. The persecutions of late 64 — burning of Christians as living torches in Nero’s gardens, throwing of Christians to wild beasts in arena spectacles — are recorded in Tacitus and in early Christian-tradition sources (notably the Roman martyrdom traditions of Saints Peter and Paul, both conventionally dated to this period).

The Christian persecution of 64 was local to Rome and in duration of perhaps several months. It established the 1st-century Roman precedent of Christian persecution as a state-organisable practice.

What followed

Nero died on 9 June 68 CE, aged 30, by suicide — having been declared a public enemy by the Roman senate after a series of failed responses to provincial revolts. His famous last reported phrase was qualis artifex pereo — “what an artist dies with me.” The Julio-Claudian dynasty ended with him; the Year of the Four Emperors (69 CE) that followed produced the Flavian dynasty under Vespasian.
