Aeschylus was born around 525 in Eleusis, a small town about  northwest of Athens, in the fertile valleys of western Attica. Some scholars argue that the date of Aeschylus's birth may be based on counting back 40 years from his first victory in the Great Dionysia.
The exact year of Aeschylus's birth remains uncertain, but scholars propose using his first victory at the Great Dionysia as a potential reference point for calculation.
