Final answer:
Propertius was concerned with Classical aesthetics, reflecting the artistic trends of the Classical Period known for realistic forms and serious expressions as in the Kritios Boy. Classical Greek culture deeply influenced Roman art and aesthetics.
Step-by-step explanation:
Propertius was similarly concerned with Classical aesthetics. His work reflects a connection and adherence to the artistic and literary traditions established during the Classical Period (480/479-323 BCE), where experimentation in realistic movement began before the end of the Archaic Period. During the Early Classical Period, also known as the "Severe Style", forms achieved naturalistic proportions and postures. This period was marked by sculptural work displaying realistic anatomy and serious expressions, which can be seen in the Kritios Boy, and for painters, the development of perspective and enriched compositions, like those on the Niobid Painter's vase.
Classical aesthetics were driven by a deep admiration and respect for the Greek cultural achievements, including their philosophy, religion, education, and art, influences that continued to be significant in Roman views and art. The Roman elite often felt both reverence for and anxiety about classical Greek culture, as it became integral to their own cultural identity and view of beauty and aesthetics.
