elements of Oedipus the King

Oedipus the king begins with prologue. It tells us the time and scene. There is no expostion and plot provided in advance. A single scene continously go through beginning to end. The conflict rises from oral actions instead of physical actions. An oracle brought back the memory of the kings' conflict. The chorus seems is Oedipus inner foil and also bring the drama rising to climax and falling to resolution.
