Aeschylus took part in many of these competitions in his lifetime. Only six tragedies have survived intact: "The Persians", "Seven against Thebes", "The Suppliants", and the trilogy known as "The Oresteia", consisting of the three tragedies "Agamemnon", "The Libation Bearers" and "The Eumenides". There is also the play "Prometheus Bound", but this was probably written by someone else. All of the surviving plays won first prize at the City Dionysia. One book, the Alexandrian "Life of Aeschylus", said that he won the first prize at the City Dionysia 13 times. Sophocles' won 18 times out of his 120 plays, and Euripides only had five wins out of about 90 plays.
