Patrons such as popes and merchants supported Renaissance artists by giving them money and housing. This allowed artists to experiment with new styles and techniques. Art changed from realistic classical styles to portraying important people through sculpture, painting, and other media. Artists like Michelangelo, Donatello, Masaccio, and Da Vinci revolutionized their fields by focusing on human anatomy, realistic features, perspective techniques, and multi-talents. Writers also changed by writing more about real life, politics, money and satire instead of just the church. Famous Renaissance writers included Petrarch, Macchiavelli, Dante, and Boccaccio.
