" The gold in Michelangelo’s strongbox represented only a fraction – considerably less than half – of his total assets, most of which were invested in property. He was not only the most famous painter or sculptor in history, he was probably richer than any artist who had ever been. This was just one of many contradictions in Michelangelo’s nature: a wealthy man who lived frugally; a skinflint who could be extraordinarily, embarrassingly generous; a private, enigmatic individual who spent three quarters of a century near the heart of power.
