The Egg Made to Stand
Legend says that when Florence held a competition for the dome, people doubted Brunelleschi. He would not reveal his scheme, and only proposed: whoever could make an egg stand on a smooth table deserved the commission. All failed; he took the egg and tapped it lightly on the table — it stood. When they protested, "We could do that too," he answered: "If I told you how to build the dome, you would say you could do that too." A genius’s scheme often looks impossible before it is shown, and obvious after.
