Final answer:
Greek sculptors aimed to depict statues that represented an ideal world, characterized by harmony and perfect proportions, with Polykleitos' Doryphoros being a prime example.
Step-by-step explanation:
Greek sculptors aimed to create statues that seemed to inhabit an ideal world, a concept often described by two words: harmony and proportions.
They sought to achieve perfect proportions and a harmonious balance in the depiction of the human form, combining the most attractive features from several live models. The sculptor Polykleitos is an excellent example of this endeavor, as he used mathematical principles to sculpt lifelike, proportional, and aesthetically pleasing forms, embodied in his sculpture of the Doryphoros. Greek statues exemplified this ideal world by portraying n-u-d-e, athletic, young, and beautifully proportioned bodies often in a stance known as contrapposto, reflecting a weight shift and natural body posture.
