What were the Sibylline Books?
The Sibylline Books were Rome's official oracle. They were scrolls of Greek hexameter verse, credited to a sibyl, an inspired prophetess, and stored in the temple of Jupiter on the Capitol. No private person could read them. When a plague, a military disaster or an alarming prodigy shook the city, the Senate told a college of priests to open the books and report.
What the priests brought back was not a forecast. It was a remedy: a sacrifice to perform, a festival to hold or a foreign god to bring to Rome. The cult of the Great Mother, Cybele, was fetched from Asia Minor in 204 BCE, during the war with Hannibal, on their advice.

What sets Sibylline Books apart
The Sibylline Books were an oracle that could not be asked a question. No one put a query to them; the priests searched the verses for a passage that fitted the trouble at hand, and the reply always took the form of a rite. Access was the point. The scrolls were state property, the college that read them grew from two men to ten and then fifteen, and to disclose their contents was a crime. Their authority lay less in any line of verse than in the Senate's control of when they were opened.
- Language: Greek hexameter verse
- Kept in: the temple of Jupiter on the Capitol, later the temple of Apollo on the Palatine
- Read by: a college of two, then ten, then fifteen priests, on the Senate's order
- First set lost: in the fire on the Capitol in 83 BCE
- Famous ruling: the bringing of the Great Mother to Rome in 204 BCE
- Final loss: early fifth century CE, blamed by Rutilius Namatianus on Stilicho
Often mistaken for something else: The Sibylline Oracles are surviving Jewish and Christian poems that foretell the fate of empires; the Sibylline Books were lost Roman state scrolls that prescribed rites and foretold nothing.
The story behind Sibylline Books
Legend says an old woman, the Sibyl of Cumae, offered nine books to King Tarquin the Proud. He refused her price; she burned three, then three more, and he bought the last three for the sum first asked. The original scrolls perished when the Capitol burned in 83 BCE, and envoys gathered a replacement set from around the Mediterranean. Augustus had it sifted and moved to the temple of Apollo on the Palatine. The poet Rutilius Namatianus blames the general Stilicho for burning the books in the early fifth century CE.
Why Sibylline Books matters
Sibylline Books show a state using an oracle to restore public calm and to license religious change, which is a different use from private fortune telling.
How to read Sibylline Books
Historians refer to them when tracing how new cults entered Rome, and the tale of the nine books is retold as a lesson about the cost of delay.
Sibylline Books in practice: an example
After a string of defeats and strange portents, the Senate would order the books opened, and the city would then hold the rites the priests said were prescribed.
Where readings of Sibylline Books go wrong
Sibylline Books are easily confused with the Sibylline Oracles, a separate set of Jewish and Christian verse texts that still survives.

What were the Sibylline Books?
They were scrolls of Greek verse oracles owned by the Roman state. A college of priests consulted them, on the Senate's order, to learn which rites would set right a crisis.
Do the Sibylline Books still exist?
No. The first collection burned in 83 BCE and its replacement was destroyed in late antiquity. Only a few quoted lines survive, and their authenticity is uncertain.

No. The Sibylline Oracles are twelve surviving books of Greek verse composed by Jewish and Christian authors between about the second century BCE and the seventh century CE.
