Sibylline Books
The Sibylline Books (Latin: Libri Sibyllini) were a collection of oracular utterances, set out in Greek hexameter verses, that, according to tradition, were purchased from a sibyl by the last King of Rome, Lucius Tarquinius Superbus, and consulted at momentous crises through the history of the Roman Republic and the Empire. Only fragments have survived, the rest being lost or deliberately destroyed.
