The fresco by Domenico Maria Canuti (1626-1684) with quadrature Henry Haffner (1640-1702), represents Romulus taken to heaven by Mars, accompanied in his rise from Jupiter, Venus supplicant and other Olympian gods, cupids with the Roman insignia and laurel wreaths. The symbolism related to the triumph of Rome and heraldry of the Altieri family is frequently. In the sky appear the constellations of Gemini, Cancer, Leo and Virgo and majestic figures of Atlases and personifications of the four seasons in the architectural decoration.
