In 15th century Italy, Florence emerged as an intellectual, financial, and artistic center under the patronage of the Medici family. Humanism flourished during this period, emphasizing secular ideals and the study of classical Greek and Latin texts. Important early Renaissance artists included Filippo Brunelleschi, who pioneered the use of linear perspective in painting and constructed the dome of Florence Cathedral, and Lorenzo Ghiberti, whose Gates of Paradise on the Florence Baptistery made use of classical influences and set new standards for realism in sculpture. Masaccio's frescoes in Florence further advanced the use of linear perspective and naturalism in figure painting.
