One of the terms that interested me during our little exercise yesterday was the s-curve that some Hellenic statues possess. I found out that this s-curve is related to the term contrapposto, which simply refers to the slouching image of a figure. These depictions often appear to be resting most of their weight on one leg. The s-curve, however, is a more advanced art technique because it involves more focus on the whole body compared to contrapposto's focus on posture. Our text book also talks about the first sculptor who used the s-curve in his art, Praxiteles. I feel that, by depicting his models as slouched in his statues, Praxiteles makes his work seem more natural and relaxed. On onlooker might think, "Hey! This guy is just like me.......only nude."
