The Cumaean Sibyl (Latin: Sibylla Cumana) was the priestess presiding over the Apollonian oracle at Cumae, a Greek colony near Naples, Italy. The word sibyl comes (via Latin) from the ancient Greek word sibylla, meaning prophetess. There were many sibyls throughout the ancient world. Because of the importance of the Cumaean Sibyl in the legends of early Rome as codified in Virgil's Aeneid VI, and because of her proximity to Rome, the Cumaean Sibyl became the most famous among the Romans. The Erythraean Sibyl from modern-day Turkey was famed among Greeks, as was the oldest Hellenic oracle, the Sibyl of Dodona, dating to the second millennium BC according to Herodotus, favored in the east.
The Cumaean Sibyl is one of the four sibyls painted by Raphael at Santa Maria della Pace (see gallery below). She was also painted by Andrea del Castagno (Uffizi Gallery, illustration right), and in the Sistine Ceiling of Michelangelo her powerful presence overshadows every other sibyl, even her younger and more beautiful sisters, such as the Delphic Sibyl.
There are various names for the Cumaean Sibyl besides the "Herophile" of Pausanias and Lactantius[1] or the Aeneid's "Deiphobe, daughter of Glaucus": "Amaltheia", "Demophile" or "Taraxandra" all appear in various references.
