What group artworks with similar characteristics into period civilization or style?

Artworks with similar characteristics are often grouped into periods, civilizations, or styles based on shared themes, techniques, materials, and cultural contexts. This classification helps scholars and art historians analyze the evolution of artistic expression and understand the influences of historical events, societal values, and technological advancements.
