spectacle (opsis)Wikipedia on Aristotle's "Poetics"
Refers to the visual apparatus of the play, including set, costumes and props (anything you can see). Aristotle calls spectacle the "least artistic" element of tragedy, and the "least connected with the work of the poet (playwright). For example: if the play has "beautiful" costumes and "bad" acting and "bad" story, there is "something wrong" with it. Even though that "beauty" may save the play it is "not a nice thing". Spectacle is like a suspenseful horror film.
