Why do people wander into museums and destroy priceless art/paintings sometimes?
Yes – I worked in the National Gallery in London for years, and many people who were disturbed and thought they had some sort of relationship with the paintings. They would write to them, or claim them and ask us to pop them in the post. A Spanish man was let out of a mental home in the early 70s, stole a dinner knife from the cafeteria and slashed The Worship of the Golden Calf for some reason. Very difficult to restore as the rather blunt knife stretched the canvas. A sharp craft knife would have caused less damage. We were all very shocked, but he had no idea of what he’d done, poor man.
