Sibylle de Cumes
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.
