The Sibylline Oracles are a collection of oracular utterances written in Greek hexameters ascribed to the Sibyls. Sibyls were 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.
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 present similar themes of the Christian Biblical Book of Revelation.
