[1] The Sibylline Oracles are a valuable source for information about classical mythology and early first millennium Gnostic, Hellenistic Jewish and Christian beliefs.
The final arrangement, thought to be due to an unknown editor of the 6th century AD (Alexandre), does not determine identity of authorship, time, or religious belief; many of the books are merely arbitrary groupings of unrelated fragments.
The Sibylline oracles are therefore a pastiche of Greek and Roman pagan mythology, employing motifs of Homer and Hesiod; Judeo-Christian legends such as the Garden of Eden, Noah and the Tower of Babel; Gnostic and early Christian homilies and eschatological writings; thinly veiled references to historical figures such as Alexander the Great and Cleopatra, as well as many allusions to the events of the later Roman Empire, often portraying Rome in a negative light.
Some have suggested that the surviving texts may include some fragments or remnants of the Sibylline Books with a legendary provenance from the Cumaean Sibyl, which had been kept in temples in Rome.
That the use of the Sibylline Oracles was not always exclusive to Christians is shown by an extract from Book III concerning the Tower of Babel as quoted by the Jewish historian Flavius Josephus, in the late 1st century AD.
Varro enumerated ten Sibyls: Persian, Libyan, Delphic, Cimmerian, Erythrean, Samian, Cumean, Hellospontian, Phrygian, and Tiburtine.
The Catholic Encyclopedia states, "Through the decline and disappearance of paganism, however, interest in them gradually diminished and they ceased to be widely read or circulated, though they were known and used during the Middle Ages in both the East and the West."
The main manuscripts date to the 14th to 16th centuries (Collins 1983:321): To this may be added the ample quotations found in the writings of the early Church Fathers.
In 1545 Xystus Betuleius (Sixt Birck of Augsburg) published at Basel an edition based on manuscript P, and the next year a version set in Latin verse appeared.
