By the battle of lake Regillus (496 BC) the dictator Postumius promised to build a temple to the war deities Castor and Pollux, if he was to be the victor. Some time later, he believed to see them fighting at the head of the Roman cavalry, and after the victory one told that they had come themselves to bring the news of the victory to Rome in the middle of the Forum. One let therefore build a splendid temple of very white marble. The very high podium gave a great majesty to the corinthian capitals.
