Une courtesane sans doute

The painting is Olympia by Edouard Manet.
In 1865, it was pilloried by people of good sense as depraved and immoral. A journalist wrote:
If the canvas of the Olympia was not destroyed, it is only because of the precautions that were taken by the administration.
Years later, Manet’s painting has been pegged as the start of modern art.
Mores change.
