There is a variety of philosophies, artistic processes, and theatrical approaches to creating plays and drama.
According to Aristotle's seminal theatrical critique Poetics, there are six elements necessary for theatre: Plot, Character, Idea, Language, Music, and Spectacle.
The 17th century Spanish writer Lope de Vega wrote that for theatre one needs "three boards, two actors, and one passion".
Others notable for their contribution to theatrical philosophy are Konstantin Stanislavski, Antonin Artaud, Bertolt Brecht, Orson Welles, Peter Brook, and Jerzy Grotowski.
Konstantin Stanislavski is considered to be the father of theater technique, as he was the first person to ever write about it, and the majority of modern western theatre theory is derived from Stanislavski's "system" in one form or another.
