How was Donatello's David different from medieval sculpture?

Donatello's David marked a significant departure from medieval sculpture by embracing naturalism and individualism. Unlike the rigid and stylized figures typical of the medieval period, Donatello's David is characterized by a relaxed contrapposto stance, realistic proportions, and detailed facial expressions that convey emotional depth. Additionally, this sculpture represents a shift towards classical themes, celebrating Humanism and the beauty of the human form, which contrasts with the predominantly religious and symbolic focus of medieval art.
