'Beyond the basilica are three beautiful columns which belong to a restoration of the Temple of Castor and Pollux, dedicated by Postumius, B.c. 484. Here costly sacrifices were always offered in the ides of July, at the anniversary of the Battle of the Lake Regillus, after which the Roman knights, richly clothed, crowned with olive, and bearing their trophies, rode past it in military procession, starting from the temple of Mars outside the Porta Capena. The existing columns are part of the temple as rebuilt by Tiberius and Drusus with the spoils taken in Germany.! The entablature which the three columns support is of great rich-ness, and the whole fragment is considered to be one of the finest existing specimens of the Corinthian order.'
