Six Axioms for Environmental Theatre (Richard Schechner, 1987)

1. The theatrical event is a set of related transactions

2. All the space is used for the performance

3. The theatrical event can take place either in a totally transformed space or in "found space"

4. Focus is flexible and variable

5. All production elements speak their own language

6. The text need be neither the starting point nor the goal of a production. There may be no verbal text at all.
