Julie Z asked me how Ross King knew that Michelangelo used a scaffold. I scoured the book and came up with an answer: M wrote a poem about it, illustrated with a sketch of him painting the ceiling, reaching his arms above his head and bending backwards like Ginger Rogers dancing with Fred Astaire--okay, not leaning that much, but definitely leaning, and complaining about it. As he seemed to complain about everything, especially his rotten family, a bunch of do-nothing brothers who just lounged around his father's house, enlarging their carbon footprints.
Now I am reading about Robert E Lee, a biography by Charles Bracelen Flood. It's almost a hagiography. Apparently Lee had some quality that led other men to like him, look up to him, and follow him, even unto death. He was offered the command of Union forces, but turned it down, unwilling to fight against his native state, Virginia.
Apparently he had something that did not outlast his life. Call it charisma. I remember how people worshipped Roosevelt when I was a tot. Nowadays he is receding into history, but Churchill said that meeting him was exhilarating, like your first taste of champagne.
Update: Apparently leaning back to paint had little or no ill effect on Michelangelo, who died at 89.
