Pace Sibilas

Four Sibyls—the Cumaean, Persian, Phrygian, and Tiburtine—are arranged in a rhythmic composition across a semi-circular lunette above an archway. Winged angels and putti hover around them, presenting scrolls and tablets inscribed with prophetic messages in Greek and Latin. The figures are rendered with the graceful movement and monumental presence characteristic of the High Renaissance.

The Sibyls represent the pagan equivalent of the Old Testament prophets, serving as a bridge between classical antiquity and Christian revelation. This synthesis was a central tenet of Renaissance Neoplatonism, which held that divine truth was partially revealed to the ancient world through these inspired women.
