Leonardo was a genius, but I'm not convinced he was a genius artist. Michelangelo was definitely a genius artist. He was insane. The Sistine Chapel? Three thousand square feet on his back? Mammoth marble statues? There's a cute little quote attributed to Michelangelo saying something like when I see a block of marble, I see the statue inside it, and all I do is chip away until it is free. Something like that. But where did he get the marble? He quarried it himself! It's not like he went down to the marble store like you or I would. He got a team of laborers and they went into the mountains and they risked life and limb for years actually finding the marble and bringing it to his studio a hundred miles away. Over two dozen major sculptures, including the David and the Pietà. Plus some pretty impressive paintings. Did I mention the Sistine Chapel? Oh, and he was an architect with buildings all around Florence and Rome. So forgive him if he isn't all that impressed with Leonardo Da Vinci, the toast of the town, the belle of the ball, and his tiny little Mona Lisa, and unfinished Last Supper. Sure he had genius ideas, but did he actually ever make that flying machine? He was a genius dreamer who could sketch up big ideas. Go dream some big ideas while sitting in the Laurentian Library and explain to me why Michelangelo should adore Leonardo Da Vinci.
