<P> Dating from the later 2nd century BC , and perhaps erected by L. Mummius Achaicus , conqueror of the Achaeans and destroyer of Corinth , the temple is 14.8 m in diameter and consists of a circular cella within a concentric ring of twenty Corinthian columns 10.66 m tall , resting on a tuff foundation . These elements supported an architrave and roof , which have disappeared . The original wall of the cella , built of travertine and marble blocks , and nineteen of the originally twenty columns remain but the current tile roof was added later . Palladio 's published reconstruction suggested a dome , though this was apparently erroneous . The temple is the earliest surviving marble building in Rome . </P>
