Charles Louis Fouquet, Duke of Belle Isle 

This pastel portrait by Maurice Quentin de La Tour, a leading portraitist of the 18th century, depicts Charles Louis Fouquet, Duke of Belle Isle, a French military leader. La Tour's distinctive style is evident in the delicate use of pastel and the lifelike rendering of the sitter's features. The Duke is depicted in a formal pose, wearing a blue uniform adorned with gold embroidery and a sash, highlighting his military rank and prestige. The painting, although lacking a specific date, likely captures the Duke during his prominent career. This work exemplifies the elegance and refined aesthetic of French portraiture during the Rococo period.
