The theatre of ancient Greece, or ancient Greek drama, is a theatrical culture that flourished in ancient Greece between c. 550 and c. 220 BC. The city-state of Athens was its centre, where it was institutionalised as part of a festival called the Dionysia, which honoured the god Dionysus.

The word diazoma originally comes from Greek language meaning belt. When talking about ancient Greek theatre it means the wide path which separated the lines of seats into two or three zones (dress circle, upper circle). In Roman theatre construction the corresponding words “praecinctiones” or “balteus” were used instead.

The Ten Thousand were a group of mercenary units, mainly Greek, drawn up by Cyrus the Younger to attempt to wrest the throne of the Persian Empire from his brother, Artaxerxes II.
