The three main masters of the RomanRenaissance, Bramante, Michelangelo and Raphael, dominated the period knownas theHigh Renaissance, leaving behind a vast architectural and artistic legacy.

Whilethelife of Italian humanists and artists took place in Roman humanist circles as well as at thepapal court, the life of ordinary Roman citizens mostly took place outdoors.
