Ottavio Vannini “The Triumph of David” / foot

(In 2007, a 21-year-old named Timothy Kubena, disturbed by the painting’s violent imagery, ripped the work off the wall of the Milwaukee Art Museum and began pounding and kicking the portion showing Goliath’s head. Once he’d punctured the piece, he took off his shoes and shirt and laid down on the museum floor to wait for police to arrive, saying to museum security, “That’s it. I just want that gone. I’m done. I come in peace.” The damage - a tennis ball-sized hole between Goliath’s eyes - was eventually restored.)
