Greek architecture was characterized by balance, harmony, and proportion. The most important building was the temple, which had a rectangular floor plan with columns surrounding it. Temples featured one of three column styles - Doric, Ionic, or Corinthian - which differed in features of the column and capital. Sculpture focused on idealized depictions of the human form and progressed from rigid poses in the Archaic period to more naturalistic proportions and movement in the Classical and Hellenistic eras. Painting decorated buildings and pottery.
