In the 1860s Courbet began to draw scenes with nude figures, nude women in a piquant form. Courbet received a lot of fame for his paintings with erotic nude figures, which he showed along with hunting scenes, guaranteeing sales and reputation.
The painting “Sleeping” was acquired by the Turkish diplomat Khalil Bee, who also purchased the painting “The Origin of the World” to include it in a private collection of paintings. This particular painting was also part of the police report in 1872, when the painting dealer held an exhibition in it. It was not allowed to be shown publicly until 1988.
