Jean-Honoré Fragonard, The Swing, 1767-68, oil on canvas, 81 × 64 cm, Wallace Collection, London. Source
The epitome of aristocratic naughtiness! A girl sits on an outdoor swing pushed by an elderly gentleman, whilst a younger man lies hidden in the foreground foliage. As the girl swings forward, she lifts her leg and tosses her shoe towards a marble statue, a movement that also grants her hiding lover a rather racy view. The Swing is one of the most famous works of the French Rococo period.
Mary Davis (c.1735–1825) rose from humble origins to marry the banker Alexander Nesbitt by 1762. She was apparently roundly unfaithful to her husband, who died insane and bankrupt in 1772. She then became the acknowledged mistress of the 3rd Earl of Bristol. Following his death in 1779, she benefited considerably from his will.
