What ancient classic literature do you love?

All readers have favorite pieces of literature, and most have favorites that can be considered classics. But what about ancient classics? What literature from the ancient world do you like? It can be anywhere from the ancient Sumerians or from ancient India or Egypt to the ancient Greeks and Romans.

I have read a lot of ancient literature and would be hard pressed to name a single one…but I can narrow it down to two: The Iliad by Homer and The Republic by Plato.
