Peter Paul Rubens “King Philip IV of Spain” / fire
(In 1985, an unidentified man was arrested for setting fire to this painting while it was on display in the Zurich Kunsthaus in Switzerland. The fire reduced the work to ashes, leaving only its Baroque frame.
The man was captured during a check of all visitors at the museum’s exits, which were closed after a guard noticed the smoke from the fire. He later justified his deed as an act of protest against environmental pollution.)
