"The Sibylline Oracles (Latin: Oracula Sibyllina; sometimes called the pseudo-Sibylline Oracles) are a collection of oracular utterances written in Greek hexameters ascribed to the Sibyls, prophetesses who uttered divine revelations in a frenzied state. Fourteen books and eight fragments of Sibylline Oracles survive, in an edition of the 6th or 7th century AD. They are not to be confused with the original Sibylline Books of the ancient Etruscans and Romans which were burned by order of the Roman general Flavius Stilicho in the 4th century AD. Instead, the text is an "odd pastiche" of Hellenistic and Roman mythology interspersed with Jewish, Gnostic and early Christian legend.
The Sibylline Oracles are a valuable source for information about classical mythology and early first millennium Gnostic, Hellenistic Jewish and Christian beliefs. Some apocalyptic passages scattered throughout seem to foreshadow themes of the Book of Revelation and other apocalyptic literature. The oracles have undergone extensive editing, re-writing, and redaction as they came to be exploited in wider circles."
