The fresco celebrates Divine Wisdom, a theme with strong political and commendable values. The complex iconography derives from the Book of Wisdom, written in the Old Testament attributed to King Solomon, the prototype of the wise and enlightened king assisted by divine wisdom, to whom Urban VIII compares himself. The personification of Divine Wisdom is seated on the throne in the center of the stage. She is surrounded by eleven female figures, incarnations of her divine attributes: on the left, Nobility (Ariadne's crown), Eternity (snake biting its tail), Soavity (lyre), Divinity (triangle), Justice (libra), Strength (club), Charity (ear of corn); on the right, Holiness (cross and flaming altar), Purity (swan), Insight (eagle) and Beauty (Chioma di Berenice). Above, among the clouds, two winged young men appear associated with the lion and the hare, symbols of love and fear of God. Each virtue identifies a precise constellation so as to reflect the astral conjuncture that occurred on the night between 5 and 6 August of 1623 at the time of the election of Pope Barberini. The frescoed vault was to be used as a protective talisman for the fortunes of the family. Order, symmetry, pastel shades bring the fresco back to the classicist vein of Baroque painting, of which Andrea Sacchi was one of the greatest supporters.
