What is the central moment of Aeschylus' Agamemnon?

The central moment in Aeschylus' Agamemnon is when the eponymous hero arrives home and walks over the purple tapestries. This is central to the main theme of justice in the play. The act of walking over the beautiful tapestries illustrates Agamemnon's hubris because he is wasting such valuable property, and it looks back to his more significant act of hubris, sacrificing his daughter. This is the main reason he dies in the end, and so by looking back to the sacrifice, and forward to his death, the scene becomes the central moment as it hints at why Agamemnon dies and suggests that it is possibly just.
