The first woman who pronounced oracles at Delphos was called Sibylla. According to Pausanias, she was the daughter of Jupiter, and of Lamia, the daughter of Neptune, and she lived a long time before the siege of Troy. From her all women were distinguished by the name of sibyls, who, without being priestesses, or even attached to a particular oracle, announced the future, and called themselves inspired. Different ages and countries have had their sibyls, or preserved predictions which bear their name, and collections were formed of them.

The greatest embarrassment to the ancients was to explain by what happy privilege these sibyls had the gift of predicting the future. Platonists found the cause of it in the intimate union which the creature, arrived at a certain degree of perfection, might have with the Divinity. Others attribute this divine property of the sibyls to the vapors and exhalations of the caves which they inhabited. Finally others attributed the prophetic spirit of the sibyls to their sombre and melancholy humor, or to some singular malady.

St. Jerome maintained that this gift was to them a recompense for their chastity; but there was at least one very celebrated one who boasted of having had a thousand lovers without being married. It would have been much more sensible in St. Jerome and other fathers of the Church to have denied the prophetic spirit of the sibyls, and to have said that by means of hazarding predictions at a venture, they might sometimes have been fulfilled, particularly with the help of a favorable commentary, by which words, spoken by chance, have been turned into facts which it was impossible they could have predicted.

It is singular that their predictions were collected after the event. The first collection of sibylline leaves, bought by Tarquin, contained three books; the second was compiled after the fire of the capitol, but we are ignorant how many books it contained; and the third is that which we possess in eight books, and in which it is doubtful whether the author has not inserted several predictions of the second. This collection is the fruit of the pious fraud of some Platonic Christians, more zealous than clever, who in composing it thought to lend arms to the Christian religion, and to put those who defended it in a situation to combat paganism with the greatest advantage.

This confused compilation of different prophecies was printed for the first time in the year 1545 from manuscripts, and published several times after, with ample commentaries, burdened with an erudition often trivial, and almost always foreign to the text, which they seldom enlightened. The number of works composed for and against the authenticity of these sibylline books is very great, and some even very learned; but there prevails so little order and reasoning, and the authors are so devoid of all philosophic spirit that those who might have courage to read them would gain nothing but ennui and fatigue. The date of the publication is found clearly indicated in the fifth and eighth books. The sibyl is made to say that the Roman Empire will have only fifteen emperors, fourteen of which are designated by the numeral value of the first letter of their names in the Greek alphabet. She adds that the fifteenth, who would be a man with a white head, would bear the name of a sea near Rome. The fifteenth of the Roman emperors was Adrian, and the Asiatic gulf is the sea of which he bears the name.
