Volgens sommige bronnen bestond er een variant waarbij de wagen draaide, om de scène het toneel op te draaien. De ''ekkyklêma'' werd gebruikt om binnenscènes in het zicht van het publiek te brengen, bijvoorbeeld moordscènes. Deze werden verbeeld in de vorm van levende afbeeldingen. Het werd voornamelijk gebruikt in tragedies om dode lichamen te onthullen, zoals het stervende lichaam van Hippolytus in de slotscène van het gelijknamige toneelstuk van Euripides, of het lijk van Eurydice gedrapeerd over het huisaltaar in Sophocles' ''Antigone''. Andere toepassingen zijn de openbaring in Sophocles' Ajax van Ajax omringd door de schapen die hij doodde terwijl hij in in zijn waanidee dacht dat het Grieken waren. De ''ekkyklêma'' werd ook gebruikt in komedies om het tragische effect te parodiëren. Een voorbeeld hiervan is te vinden in Aristophanes' ''Thesmophoriazusae'', waar Agathon op een ''ekkyklêma'' het toneel wordt opgereden om de komische absurditeit van de scène te versterken.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Locations were generic, and denoted by paintings mounted on the skene that were just one part of the overall stage picture. These pictures were called ''pinakes'' and could be changed between performances ([[Item:Q30663|see story F.01]]). A different technique was used to change the scene during the performance, if that was required: the ''[[Item:Q23827|periaktoi]]'' (Q23827, from the Greek word meaning ‘revolving’ or ‘rotating prisms’ or ‘angular frames’). ''Periaktoi'' were three-sided wooded frames covered with painted canvas – a different scene on each side. The frames were fixed to a central, vertical axis embedded in the stage floor, so they could be turned in order to change the location of the scene.

''Machines were an essential part of the staging of Greek dramas, enabling changes of scene. Wagons and revolves were used to bring a dramatic tableau onto the stage, while the rotating ''periaktoi'' created rapid changes of location.''&lt;br /&gt;
&lt;br /&gt;
[[File:IO2 A.01 03.jpg|400px|thumb|right|Plan of Roman theatre with periaktoi, from Vitruvius' De Architectura]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
An ''[[Item:Q627|ekkyklêma]]'' (Q627, from ''ekkuklein'', to roll out) was a wheeled platform or wagon rolled out of the central door of the skene at the back of the stage, bringing a small scene or tableau into view. Some sources suggest there was a variation in which the wagon revolved, to turn the scene onto the stage. The ''ekkyklêma'' was used to bring interior scenes out into the view of the audience, for example murder scenes, which were imagined in the form of living pictures. It was mainly 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 they were Greeks. The ''ekkyklêma'' was also used in comedy to parody the tragic effect. An example of this is in Aristophanes’ ''Thesmophoriazusae'', when Agathon is wheeled onstage on an ''ekkyklêma'' to enhance the comic absurdity of the scene.&lt;br /&gt;
&lt;br /&gt;
Compared with simply opening the doors or curtain in the ''skene'' to reveal the scene, the ''ekkyklêma'' offered an important benefit. The semi-circular auditorium of the Greek amphitheatre meant the view of the stage for some members of the audience was very much from the side, so the inner space behind the skene would not have been in view. By rolling or turning the ''ekkyklêma'', it ensured all spectators could see it clearly, while the movement of the mechanism added to the sense of revelation. In Greek theatre there was a strict code forbidding violent deaths being acted out on stage, so the ''ekkyklêma'' also provided a permissible means to bring the result of a murder or death onto the stage, with much greater spectacle and dramatic impact than simply having another character report the events.&lt;br /&gt;
&lt;br /&gt;
The Greek theatre did not provide a total, illusionistic stage environment. Locations were generic, and denoted by paintings mounted on the skene that were just one part of the overall stage picture. These pictures were called ''pinakes'' and could be changed between performances ([[Item:Q30663|see story F.01]]). A different technique was used to change the scene during the performance, if that was required: the ''[[Item:Q23827|periaktoi]]'' (Q23827, from the Greek word meaning ‘revolving’ or ‘rotating prisms’ or ‘angular frames’). ''Periaktoi'' were three-sided wooded frames covered with painted canvas – a different scene on each side. The frames were fixed to a central, vertical axis embedded in the stage floor, so they could be turned in order to change the location of the scene. This gave then opportunity of visualising different locations depending on the configurations of the ''periaktoi''.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
We don’t have detailed records of the placements and mechanisms of the ''periaktoi'', but some recreations of Greek theatres suggest at least two larger ''periaktoi'' used at the openings on top of the ''logneion proskenion'' on either side of the central opening of the ''skene''. These ''periaktoi'' were housed within the ''skene'' and were probably turned by hand. Marcus Vitruvius Pollio mentioned the ''periaktoi'' in his ten volume ''[[Item:Q466|De Architectura (Q466)]]'' around 13 BCE. In the 5th book he focused on Greek and Roman theatre architecture, where he explained the triangular prisms. In Vitruvius’ floorplan for the Roman theatre, we can see a set of six ''periaktoi'' placed in a vee formation on top of the ''proskenium'' instead of within the building itself. However, whether these were turned by hand or by an interlocking mechanism made of gears and chains is unclear. The 2nd century Greek grammarian Julius Pollux describes the ''periaktoi'' in his dictionary ''The Onomaticon'' which was reprinted in 1502. This together with the first illustrated version of ''De Architectura'', published in 1511, may be the reason why the ''periaktoi'' and many other theatre machines from Antiquity were revived during the Renaissance. Certainly, theatres of the Renaissance made use of ''periaktoi'', interlocked with either ropes or chains to so they could be turned simultaneously, providing the sense of ‘magical’ transformation that was sought.&lt;br /&gt;
&lt;br /&gt;
Rolling and turning mechanisms were used by the Greek theatres of Antiquity. The ingenuity of these devices and the flexibility they present to achieve quick changes of scene means they have been in use through much of the history of theatre staging since. The mechanical principle of the ''periaktoi'' can also be found in modern Trivision billboards, which allows for up to three different messages to be displayed: a modern application of an ancient device.&lt;/div&gt;</summary>
