Santa maria del polpolo, cappella chigi cupola

Looking upward into the gilded dome, the central medallion shows God in a dynamic gesture of creation. Surrounding the center are eight panels featuring the seven planets of the Ptolemaic system and the fixed stars, each represented by a classical deity like Jupiter or Mars. Each deity is paired with a celestial angel who directs the movement of the sphere according to divine will.

This work is a primary visual manifestation of Renaissance Neoplatonism, synthesizing Christian theology with the classical 'Harmony of the Spheres.' It illustrates the 'prisca theologia' tradition, where pagan astrological forces are integrated into a singular Christian cosmic order governed by divine intelligence.
