The Greeks developed standard forms and dramatic conventions for both comedies and tragedies.

A Playwrights continued to introduce innovations, but essentially they adhered to prescribed conventions.

Therefore, murders, suicides, and other acts of violence occurred offstage. D The Greek concept of moderation is reflected in still another convention, in which any character who acted in an excess of passion was usually punished in the story.
