Les affinités électives (Elective Affinities), 1933 by Rene Magritte (1898-1967)
One night, I woke up in a room in which a cage with a bird sleeping in it had been placed. A magnificent error caused me to see an egg in the cage, instead of the vanished bird. I then grasped a new and astonishing poetic secret, for the shock which I experienced had been provoked precisely by the affinity of two objects—the cage and the egg—to each other, whereas previously this shock had been caused by my bringing together two objects that were unrelated.
