Ekkyklema

An ekkyklêma or eccyclema (εκκύκλημα; "roll-out machine") was a wheeled platform rolled out through a skênê in ancient Greek theatre. It was used to bring interior scenes out into the sight of the audience. Some ancient sources suggest that it may have been revolved or turned.

It is primarily used in tragedies for revealing dead bodies, such as Hippolytus' dying body in the final scene of Euripides' play of the same name, or the corpse of Eurydice draped over the household altar in Sophocles' Antigone. Other uses include the revelation in Sophocles' Ajax of Ajax surrounded by the sheep he killed whilst under the delusion that they were Greeks. The ekkyklêma is also used in comedy to parody the tragic effect. An example of this is in Aristophanes' Thesmophoriazusae when Agathon, portrayed as an effeminate, is wheeled onstage on an ekkyklêma to enhance the comic absurdity of the scene.
