Refers to presenting standing figures with opposing alternations of tension and relaxation around a central axis a convention that dominates Greek Classical art?

The description refers to the contrapposto stance, a key convention in Greek Classical art that creates a dynamic balance between tension and relaxation in the depiction of standing figures. This technique involves positioning the figure's weight on one leg while the other leg is relaxed, resulting in a naturalistic and fluid pose that emphasizes the human form. This approach not only conveys a sense of movement but also reflects the Greeks' understanding of human anatomy and their pursuit of ideal beauty. The central axis serves as a focal point, enhancing the overall harmony and compositional balance of the artwork.
