The ancient Greeks were wonderful architects. They invented three types of columns to support their buildings. Each was beautiful. From a distance, each column looked straight, no matter which of the three designs they used. But up close, the columns might actually tilt a bit, or lean left or right, to better support each building. The Greeks wanted things to be beautiful, but they also wanted things to be strong.
Nearly every public building in ancient Greece incorporated one or more of these three designs. Even in ancient Sparta, these three column designs could be found all over town. These designs are still used today. These designs have certainly withstood the test of time.
