Why was Doryphoros or Spear Bearer famous throughout the ancient worl?

The Doryphoros, or Spear Bearer, is famous for its embodiment of classical Greek ideals of beauty, proportion, and the human form, as exemplified by the sculptor Polykleitos around 440 BCE. It exemplifies the use of contrapposto, a stance that conveys a sense of movement and life, and represents the perfect balance between muscularity and harmony. The statue also served as a model for later Roman sculptures and influenced the representation of the male figure in Western art. Its significance lies not only in its aesthetic qualities but also in its philosophical connections to the idea of the ideal man in ancient Greek culture.
