When Aeschylus first began writing, the theatre was new.
Some playwrights like Thespis had made the cast bigger to include an actor who was able to talk with the chorus.
Aeschylus added a second actor, allowing for more drama; and the chorus became less important.
He is said to have been the first to use skenographia, or scene-decoration, though Aristotle said the first person was Sophocles.
Aeschylus also added more details to the costumes, and had his actors wear platform boots, called cothurni, to help the audience see them better.
When they walked on stage in the first performance of the Eumenides, the chorus of Furies were so frightening in looks that they made young children faint, old men urinate, and pregnant women go into labor.

His plays were written in the strict style of Greek drama.
They were in verse and no violence could be performed on stage.
The plays had to be set away from normal life in Athens, either by telling stories about the gods or by being set, like The Persians, in a far-away place.
Aeschylus' work has a strong moral and religious emphasis.
The Oresteia plays were about man's position in the universe in relation to the gods, the laws of the gods, and punishment from the gods.

Fifty years after Aeschylus' death, the comic playwright Aristophanes praised him in The Frogs.
Aeschylus is a character in the play and says that his Seven against Thebes "made everyone watching it to love being warlike" (line 1022); with his Persians, he says he "taught the Athenians to desire always to defeat their enemies" (line 1026–7).
 He says that his plays helped the Athenians to be brave and virtuous (line 1039ff).
