The Odeion
The Odeon was a smaller roofed theatre, theatrum tectum, that sat 1500 spectators built in 80 BC. The theatre follows the plan of other Roman theatres and odeon structures. Where the Large Theatre was used primarily for staging drama, the Odeon was used for musical concert performance. The thin walls and rectangular plan lead to the conclusion that the roof would have been wood rather than vaulted stone. There are two raised tribunalia, platforms, above the seating that were reserved for important visitors. These platforms are cut off from the general seating completely with entranced from narrow staircases near the stage.
The stage
The stage featured five entrances on the back wall. A large palatial double door was center with two smaller double doors on either side. Two small single doors were located at either end. There is a large doorway that opens to a colonnade leading to the Large Theatre at the west end of the stage. Opposite this is a similar doorway opening up to the street. Behind the stage is a long dressing room or postscaenium. Following ancient theatre tradition, a machine used for suspending the gods and heroes was located at the left side of the stage
