What are the motifs in Lysistrata by Aristophanes?

War and peace are recurring ideas. It is war that has devastated Athens. The chorus is made up of old men because there are no young men left. Those who have not been killed in the war, now in its twentieth year, are off at war. The women remain behind and must manage children and property with little assistance. Young women have no one to wed. Lysistrata says that when men return from war, even the old ones can find wives. But once their time has passed, young women will never find a husband. This is one of the injustices of war, the abandonment of the women. The Peloponnesian War provides the background for this comedy, but the subject, the tragedy that this war brought to Athens, illustrates that war victimizes everyone.
