One of Fragonard's most renowned paintings is "The Swing", also known as "The Happy Accidents of the Swing" (its original title), an oil painting in the Wallace Collection in London. It is considered to be one of the masterpieces of the rococo era, and is Fragonard's best known work. The painting portrays a young gentleman concealed in the bushes, observing a lady on swing being pushed by her spouse, who is standing in the background, hidden in the shadows, as he is unaware of the affair. As the lady swings forward, the young man gets a glimpse under her dress.
