Sandro del Prete
A satire in two scenes:
A bullfighter is standing in the arena as an unsuspecting house cat passes by. The bullfighter recognizes the head of a wild bull in the shadow of the cat. Skillfully, he thrusts his sword into the beast's neck. From his victorious attitude, we can deduce that he believes he has accomplished his objective. The impaled animal remains lying on the ground. The cat however, saunters away without its shadow, as if nothing had happened.
