This is an artists rendition based on the digs of what the theater originally looked like.  The theater was situated so that the sun was to the back of the audience and shown on the stage.  Most plays are thought to have been performed during daylight hours.  They had stuff coming up from under the stage as well as ropes and pulleys from the ceiling when they wanted certain "gods" to descend.

 dah,dah, ta dum ti dum!

where's Waldork?  

Powerful earthquakes took the city down.  After the first in 363 a.d. the city was partially rebuilt but the second considerably more powerful in 749 a.d. leveled the city and it was not built again until the modern era.   For a thousand years it was little more than a pit stop between Damascus and Cairo.  For the 1,000 years before that it was the capital of the Decapolis or the 10 Greek/Roman cities that ruled the area.
