The Sibylline Oracles are now generally regarded as heathen fragments largely interpolated by unscrupulous men during the early ages of the Church. For an interesting account of these somewhat perplexing documents, see Burton’s Lectures on the Ecclesiastical History of the First Three Centuries, Lect. xvii. The prophecies of Hystaspes were also commonly appealed to as genuine by the early Christians. [See (on the Sibyls and Justin M.) Casaubon, Exercitationes, pp. 65 and 80. This work is a most learned and diversified thesaurus, in the form of strictures on Card. Baronius. Geneva, 1663.]
