How are both classical Greek and Roman art with Italian Renaissance art different?

Classical Greek and Roman art primarily focused on idealized forms and the representation of human figures with an emphasis on proportion, symmetry, and realism, often celebrating Humanism and mythology. In contrast, Italian Renaissance art introduced a renewed interest in naturalism, perspective, and the exploration of individual emotion and experience, influenced by the revival of classical ideals but infused with a more profound spiritual and humanistic depth. While classical art often depicted gods and heroic figures, Renaissance art encompassed a broader range of subjects, including everyday life and religious themes, showcasing advancements in techniques like chiaroscuro and linear perspective. Additionally, the Renaissance's engagement with science and philosophy marked a shift towards a more comprehensive understanding of the world, diverging from the more static representations of earlier classical traditions.
