In 495 BC, the last king of Rome (Lucius Superbus) attacked the emerging Roman Republic at the Battle of Lake Regillus. Mythology claims Castor and Pollux were sent to the conflict by their father Zeus to help defeat the king. In appreciation, a temple was constructed to honor the Dioscuri twins. It was reconstructed in 117 BC, 73 BC and 6 AD. These three fluted Corinthian columns are all that remain of the 19 that framed the temple over two thousand years ago.
