concrete and stone foundations allowed for a free standing Roman theatre and amphitheatre. The stage and scaenae frons sections of the theatre is attached directly to the auditorium, making both a single structure enclosed all around, whereas Greek theatres separate the two. This created acoustic issues requiring different techniques to overcome. This architecture was the model for nearly all future theatres of Rome and throughout the empire. Notable structures that used a similar style are the Theatre of Marcellus and the Theatre of Balbus, both of which can be seen on the marble plan of the city. Associated temple complex In order to build the theatre as a permanent stone structure, a number of things were done, including building outside the city walls. By dedicating the theatre to Venus Victrix and building the temple central within the cavea, Pompey made the structure a large shrine to his personal deity. He also incorporated four Republican temples from an earlier period in a section called the "Sacred Area" in what is today known as Largo di Torre Argentina. The entire complex is built directly off the older section which directs the structure's layout. In this manner, the structure had a day-to-day religious context and incorporates an older series of temples into the newer structure. Temple A was built in the 3rdcenturyBC, and is probably the Temple of Juturna built by Gaius Lutatius Catulus after his victory against the Carthaginians in 241BC. It was later rebuilt into a church, whose apse is still present. Temple B, a circular temple with six columns remaining, was built by Quintus Lutatius Catulus in 101BC to celebrate his victory over Cimbri; it was Aedes Fortunae Huiusce Diei, a temple devoted to the "Luck of the Current Day". The colossal statue found during excavations and now kept in the Capitoline Museums was the statue of the goddess herself. Only the head, the arms, and the legs were of marble: the other parts, covered by the dress, were of bronze. Temple C is the most ancient of the four, dating back to the 4th or 3rdcenturyBC, and was probably devoted to Feronia, the ancient Italic goddess of fertility. After the fire of 80AD, this temple was restored, and the white and black mosaic of the inner temple cell dates back to this restoration. Temple D is the largest of the four; it dates back to the 2nd centuryBC with
