There is no doubt but that in ancient times there existed certain women, who, led by a frenzied enthusiasm, uttered obscure sentences, which passed for predictions with the credulous people who went to consult them. Virgil and Ovid represent Æneas as going to the cave of the Cumæan Sibyl, to learn from her the success of the wars he should be engaged in. Plato, Strabo, Plutarch, Pliny, Solinus, and Pausanias, with many other writers, have mentioned the Sibyls; and it would be absurd, with Faustus Socinus, to affirm that no Sibyls ever existed. Indeed, Plato and other authors of antiquity go so far as to say, that by their productions they were essentially the benefactors of mankind. Some mention but one Sibyl, who was born either at Babylon or at Erythræ, in Phrygia. Diodorus Siculus mentions one only, and assigns Delphi as her locality, calling her by the name of Daphne. Strabo and Stephanus Byzantinus mention two, the one of Gergæ, a little town near Troy, and the other of Mermessus, in the same country. Solinus reckons three; the Delphian, named Herophile, the Erythræan, and the Cumæan. According to Varro, their number amounted to ten, whose names, in the order of time which Pausanias assigns them, were as follows:
The first and the most ancient was the Delphian, who lived before the Trojan war. The second was the Erythræan, who was said to have been the first composer of acrostic verses, and who also lived before the Trojan war. The third was the Cumæan, who was mentioned by Nævius in his book on the first Punic war, and by Piso in his annals. She is the Sibyl spoken of in the Æneid, and her name was Deïphobe. The fourth was the Samian, called Pitho, though Eusebius calls her Herophile, and he makes her to have lived about the time of Numa Pompilius. The fifth, whose name was Amalthea, or Demophile, lived at Cumæ, in Asia Minor. The sixth was the Hellespontine Sibyl, born at Mermessus, near Troy. The seventh was the Libyan, mentioned by Euripides. Some suppose that she was the first who had the name of Sibyl, which was given to her by the people of Africa. The eighth was the Persian or Babylonian Sibyl, whom Suidas names Sambetha. The ninth was the Phrygian, who delivered her oracles at Ancyra, in Phrygia. The tenth was the Tiburtine, who was called Albunea, and prophesied near Tibur, or Tivoli, on the banks of the Anio. In the present story Ovid evidently intends to represent these various Sibyls as being the same person; and to account for her prolonged existence, by representing that Apollo had granted her a life to last for many ages.
