Go to the Galleria Dell'...
Go to the Galleria Dell' Accademia and see Michelangelo's David. It truly is a spectacular representation of the human form! The one thing to notice is that the right hand is out of proportion to the rest of the body! I read in one place that they think that this oversized hand is supposed to represent the hand of God.
