What did Giotto introduce ito paintings of religious scenes?

Giotto introduced a sense of realism and emotional depth to religious scenes, moving away from the flat, stylized representations typical of Byzantine art. He utilized techniques such as chiaroscuro and perspective to create a three-dimensional effect, allowing figures to appear more lifelike. His focus on human emotion and naturalistic details helped to convey the spiritual narratives in a more relatable manner, setting the stage for the evolution of Renaissance art.
