1. During the Renaissance, humanists were inspired by classical art, literature, and philosophy from antiquity and studied original texts in Latin and Greek. Johannes Gutenberg's invention of the printing press allowed humanist ideas to spread more widely. 2. Scientists like Copernicus developed new theories like a heliocentric solar system, and artists revived classical styles and proportions in their works. Renaissance architecture used classical elements like columns and semicircular arches. 3. Painters used techniques like linear perspective and idealized figures to create the illusion of depth and beauty. Sculptors also drew from classical models to depict realistic and idealized nudes in marble and bronze.
