The most influential artistic shift of the Hellenistic Period that likely had a significant impact over time is A. The shift toward more naturalistic sculpture.
This period saw a move away from the strict idealism of earlier Greek art to a greater emphasis on realism, emotion, and the depiction of individual characters and experiences. This naturalistic style influenced not just subsequent Greek art but also Roman art and European art in later periods, laying the groundwork for developments in realism and expression that would continue to evolve in the centuries to come.
