Theatre of Dionysus instance of Greek theatre
Sanctuary and first theatre
The cult of Dionysus was introduced to Attica in the Archaic period with the earliest representation of the God dating to c. 580 BC. The City Dionysia (or Great Dionysia) began sometime in the Peisistratid era. and was reorganised during the Kleisthenic reforms of the 520s BC. The first dramatic performances likely took place in the Agora  where it is recorded that the wooden bleachers set up for the plays (ikria)  collapsed. This disaster perhaps prompted the removal of dramatic production to the Sanctuary of Dionysus on the Akropolis, which took place by the time of the 70th Olympiad in 499/496 BC. At the temenos the earliest structures were the Older Temple, which housed the xoanon of Dionysos, a retaining wall to the north and slightly further up the hill a circular terrace that would have been the first orchestra of the theatre. The excavations by Wilhelm Dörpfeld identified the foundations of this terrace as a section of polygonal masonry, indicating an archaic date. It is probable there was an altar, or thymele,  in the centre of the orchestra. No formally constructed stone seating existed at this point, only ikria and the natural amphitheatre of the hill served as theatron.Besides the archaeological evidence, there is the literary testimonia of the contemporary plays from which there are clues as to the theatre’s construction and scenography. For this earliest phase of the theatre there is the work of Aeschylus, who flourished in the 480-460s. The dramatic action of the plays does point to the presence of a skene or background scenery of some description, the strongest evidence of which is from the Oresteia that requires a number of entrances and exits from a palace door. Whether this was a temporary or permanent wooden structure or simply a tent remains unclear since there is no physical evidence for a skene building until the Periclean phase. However, the hypothesis of a skene is not contradicted by the known archaeology of the site. The Oresteia also refers to a roof from which a watchman looks out, a step to the palace and an altar. It is sometimes argued that an ekkyklema,  a wheeled trolly, was used for the revelation of the bodies by Clytemnestra at line 1372 in Agamemnon amongst other passages.  If so it was an innovation of Aeschylus' stagecraft. However, Oliver Taplin questions the seemingly inconsistent use of the device for the dramatic passages claimed for it, and doubts whether the mechanism existed in Aeschylus' lifetime.
