How does contrapposto create a sense of movement in Donatello’s St. George?

In Donatello’s St. George (c. 1415), the use of contrapposto creates a sense of movement by establishing a natural rotation of the figure's central body axis and a shift in weight.1

By poising the statue so that the weight rests on one leg while the other is subtly adjusted, Donatello emphasizes a dynamic balance between repose and action. This disposition of the legs and shoulders breaks the static frontality common in medieval art, animating the figure and suggesting the internal organic movement that denotes life.21

Beyond the physical stance, this technique serves as a psychological achievement, representing a moment of "pause" that captures a sense of potential energy. Through this sophisticated manipulation of the human form, Donatello rendered the statue as a self-activating, functional organism, marking a significant departure from earlier sculptural traditions.13
