Salon d'Hercule, State room in Palace of Versailles, France

The Salon d'Hercule is a state room in the Palace of Versailles decorated with marble surfaces, bronze ornaments, and a large ceiling painting of the Apotheosis of Hercules created by François Lemoyne. The space connects the Royal Chapel in the North Wing to the grand appartement du roi on the palace's first floor.

The room occupies the upper level of a chapel used from 1682 to 1710. Robert de Cotte began its decoration in 1712, but work stopped at Louis XIV's death in 1715 and resumed in 1725 under Louis XV, with Ange-Jacques Gabriel as architect. Completed in 1736, it takes its name from François Lemoyne's ceiling painting Apotheosis of Hercules.

The room takes its name from Lemoyne's ceiling, but its walls hold two Veronese canvases: Rebecca at the Well above the Antin marble fireplace, and opposite it the Feast in the House of Simon, given to Louis XIV by Venice in 1664 and carved frame by Jacques Verberckt. The latter left for the Louvre in 1832 and came back in 1961.

The salon occupies the upper level of a former chapel, so it is reached by the palace's stairs rather than from the ground floor. It links the North Wing chapel to the central block and opens onto the salon de l'Abondance. It faces east and west, and is the largest room in the château.

The room was inaugurated on January 26, 1739, with a grand ball celebrating the wedding of Louis XV's daughter to a Spanish Infante. This celebration marked one of the most splendid occasions of Louis XV's early reign.
