One day in 1402, into the middle of Rome, came a young man called Filippo Brunelleschi and a teenage boy called Donatello. They were fascinated by everything that they saw. They measured ancient ruined buildings, they drew things and they dug around for weeks looking for bits of broken statues and painted pottery that they could stick together. They were probably the world's first archaeologists. By the time they went back home to Florence, they knew more about Ancient Roman architecture and sculpture than anyone had known for about a thousand years. Brunelleschi became a very famous architect and Donatello became a very famous sculptor.
