Scenography (set design).

Scenography (Set Design) is concerned with the environment of the play (the performance space) as it is realized on the stage.

“The reality of a theatrical performance has no inherent connection with its realism, the degree of fidelity with which it reproduces or reflects the fact, as we say, of actual Life. A play becomes real to the degree that any audience succeeds in identifying itself with the lives and deeds portrayed.” (Lee Simonson)
