Titian painted the Venus of Urbino in 1538 in Venice on commission from Guidobaldo II della Rovere, the 24-year-old heir to the Duchy of Urbino, almost certainly as a wedding gift for his 10-year-old bride Giulia Varano. The 119 × 165 centimetre oil-on-canvas shows a naked young woman lying on a red velvet daybed inside a Renaissance bedroom, looking directly out of the picture at the viewer with calm self-possession.

The 1865 Paris Salon hung Manet's Olympia high enough that visitors had to look up to see it, and they did, in numbers large enough to require a guard. The painting was not scandalous because it showed a nude — half the Salon showed nudes. It was scandalous because of a specific set of decisions Manet had made about how the nude was painted, who she was, and what she was looking at. The mechanism, step by step.
