We have all seen images of those stunning temples of ancient Greece. In contrast to a modern place of worship, the ancient Greeks believed that their temples were places where their gods came to dwell, and so literally wanted to make them worthy of the gods. This talk examines the art and architecture of the ancient Greek temple: how did the design emerge as it did? What is the significance of Doric, Ionic, and Corinthian columns? What can we learn from the sculpted art on them? How were these buildings actually used? We will look at the temple of Zeus at Olympia as a worked example, and finish by examining the legacy of Greek temple design in neo-classical and modern architecture.
