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.
