The OresteiaThe Bridge Theatre, London⭑⭑⭑⭑⭑THE ORESTEIA by Aeschylus — strictly not one play, although it is often performed as such, but a trilogy of connected tragedies, Agamemnon, The Libation Bearers, and The Eumenides — is one of the foundational texts of Western theatre. It might be 2,500 years old, but its characters, and its themes, have echoed loudly and proudly down the centuries in our Western world.
