Michelangelo’s David is recognised as one of the most sublime works in the history of sculpture, but according to the director of Florence’s Accademia Gallery, dusting it is much like cleaning a bathroom.

“You know when you clean a bathroom, you clean and clean and think you’ve done a great job but then you spot some dust and wonder ‘where did that come from?’,” Cecilie Hollberg said on Monday. “This is what it’s like. Dust is everywhere.”
