Diana Lounge, State room in Palace of Versailles, France.

The Salon de Diane is a room in the King's Grand Apartment at the Palace of Versailles, measuring 10.34 m by 8.70 m with a height of 7.55 m. Its centerpiece is a white marble bust of Louis XIV by Gian Lorenzo Bernini, dated 1665, set in an arched niche crowned by two gilded putti holding a garland. The niche is flanked by pilasters with green, gray, and dark red marble inlays, and two smaller white marble busts of Roman women stand on either side.

The room was commissioned by King Louis XIV, who engaged a group of leading artists of the time to decorate it. This artistic collaboration was part of the broader embellishment of the palace during the Sun King's reign.

The room takes its name from Diana, Roman goddess of the hunt, and its painted programme follows her legend: Blanchard's ceiling shows her on her chariot presiding over hunting and navigation, while grisaille medallions above the doors depict Diana and Actaeon, Diana protecting Arethusa, a flower offering and a sacrifice to Diana. The four lunettes instead show Alexander, Cyrus, Julius Caesar and Jason, pairing the goddess with rulers and heroes.

The room is readily accessible from the adjacent halls and opens to visitors during regular palace hours. It is worth taking time to observe the ceiling paintings from different angles, as the details are visible from multiple viewpoints.

The white marble bust of Louis XIV in the niche was carved by Gian Lorenzo Bernini in 1665, during the artist's stay in Paris. The two antique busts beside it are Roman: one a woman, one an empress, their heads in white marble set over onyx and brocatelle drapery. The empress's marble comes from Seravezza, in the Carrara basin.
