Augustus and the Tiburtine Sibyl

This Augustus and the Tiburtine Sibyl from 1664, held in the Royal Collection, depicts the legend in which the Sibyl of Tivoli showed Emperor Augustus a vision of the Virgin and Child in the sky, foretelling the birth of Christ. The subject was popular in Counter-Reformation art as it linked classical antiquity to Christian revelation. This late work by Cortona was likely painted for an important patron given its placement in the British Royal Collection, which acquired significant Italian Baroque paintings through diplomatic gifts and purchases.

The composition contrasts the earthly figures of Augustus and the Sibyl with the celestial vision above, using dramatic lighting to distinguish between the temporal and divine realms. Cortona's fluid brushwork and warm palette create a visionary atmosphere bridging classical and Christian iconography.
