The sun god, Apollo, guides his chariot through the center of the composition. Borne by clouds, the goddess, Juno appears. On the ground, Bacchus, the god of wine rides an ass with a crown of grape leaves on his head. This is the moment of his coronation and he is surrounded by nymphs and other members of his retinue. He is accompanied by Diana, the goddess of the hunt, who can be identified by her symbol, the half moon. In the background, Venus, the goddess of beauty, floats over the sea.

This painting, whose composition is based on classical Greco-Latin mythology, is a sketch for the ceiling of the Hall of Columns at Madrid's Royal Palace, which was painted in 1762.
