Saint Catherine of Siena receiving the Heart of Christ in Exchange for her own

Christ, shown with a radiant halo and draped in red, advances from a ledge toward Saint Catherine of Siena, who leans back and is steadied by a man in pale brown and two angels. Catherine wears a white veil over a dark robe, while the other figures are clothed in soft blues and creams, set against a stone architectural backdrop with a distant landscape. The composition runs diagonally from Christ to Catherine, and the palette uses warm flesh tones, bright whites, and glowing halos, rendered with smooth, idealized modeling typical of late Renaissance to early Baroque religious painting.
