The ceiling is decorated with two allegorical figures painted on canvas and applied to decorate the halls of the Palace built by Catherine the Great of Russia, between 1762 and 1768, she commissioning the artworks to the most important Master of the Venetian Academy Giambattista Pittoni. The theme of female allegories was commissioned personally from by Catherine II, where the two figures recall "Perseverance", who holds a snake in her right hand, and "Magnificence", who holds an ovate in her left hand.
