Patrons, including popes and merchants, supported artists financially which allowed artists to focus solely on their work. Art during the Renaissance revolutionized as the focus shifted away from religious themes and toward classical influences with an emphasis on realistic human forms and perspective. Famous Renaissance artists like Michelangelo, Donatello, Masaccio, and Da Vinci advanced painting and sculpture techniques. Renaissance writers also flourished as they wrote poetry, plays, and prose exploring experiences, politics, money, and satire.
