This diagram shows how the perspective works in Manet's famous painting Un bar aux Folies Bergère. We are viewing the woman at an angle, and while the man is outside our field of view, his reflection can be seen.
Astounding! But it's not just a technical feat. It allowed Manet to make a deep point. While the woman is busy serving her customer, she is internally completely detached - perhaps bored, perhaps introspective. She is SPLIT.
To fully understand the painting you also need to know that many of the barmaids at the Folies Bergère also served as prostitutes. Standing behind the oranges, the champagne and a bottle of Bass ale, the woman is just as much a commodity as these other things. But she is coldly detached from her objectification.
The woman in the painting was actually a real person, known as Suzon, who worked at the Folies-Bergère in the early 1880s. For his painting, Manet posed her in his studio.
Before I understood this painting, I wasn't really looking at it - I didn't see it. I didn't even see the green shoes of the trapeze artist. I can often grasp music quite quickly. But paintings often fail to move me until someone explains them.
When Manet came out with this painting in 1882, some critics mocked him for his poor understanding of perspective. Some said he was going senile. It was, in fact, his last major painting. But he was a genius, and he was going... whoosh... over their heads, just like he went over mine.
