Picture this: A student wears a set of goggles that transport her from a classroom in Athens, Georgia, to the Parthenon, 5,600 miles away in Athens, Greece. In an interactive, 3-D world, she peers up and down each of the 17 columns on the temple’s side and examines the fluted shafts. She notes that they have no bases. It’s easy to understand the differences between Ionic and Doric architecture here: rather than relying on textbook descriptions, those differences come to life before her eyes.
