Aeschylus' Works
Aeschylus wrote between 70 and 90 plays, of which six or seven survive complete along with various fragments of others, notably The Netfishers (Diktyoulkoi) and Spectators at the Isthmian Games (Isthmiastai). His first play was presented in c. 499 BCE and he claimed his first of 13 festival victories in 484 BCE. His complete surviving plays are:
The Persians (472 BCE) - set after the Greek victory (less than a decade earlier) over the Persians at Salamis and Xerxes' return to Persia.
Seven Against Thebes (467 BCE) - about the cursed Labdacids and the siege of Thebes. It is the third part of a trilogy which included Laius (part I) and Oedipus (part II).
