1) The UNITY OF TIME: the play should take place within the fictional space of one 24-hour period
2) The UNITY OF PLACE: the play should be confined to a single fictional location or to locations accessible to one another within the imaginary period covered by the play.
3) The UNITY OF ACTION: the play should be uniformly "serious" and not interrupted by emotionally incongruous moments of comic relief.
4) The play should be characterized by a general ELEVATION OF TONE: the language should be heightened and poetic, the theme majestic and philosophical.
5) The HERO SHOULD BE A NOBLEMAN or king.
