<human>: Background: Aeschylus (UK: , US: ; Greek: Aiskhulos Aiskhulos; Ancient Greek: [ais.khy.los]; c. 525/524 - c. 456/455 BC) was an ancient Greek tragedian. He is often described as the father of tragedy. Academics' knowledge of the genre begins with his work, and understanding of earlier tragedies is largely based on inferences from his surviving plays.
Context: When Aeschylus first began writing, the theatre had only just begun to evolve, although earlier playwrights like Thespis had already expanded the cast to include an actor who was able to interact with the chorus. Aeschylus added a second actor, allowing for greater dramatic variety, while the chorus played a less important role. He is sometimes credited with introducing skenographia, or scene-decoration, though Aristotle gives this distinction to Sophocles. Aeschylus is also said to have made the costumes more elaborate and dramatic, and having his actors wear platform boots (cothurni) to make them more visible to the audience. According to a later account of Aeschylus's life, as they walked on stage in the first performance of the Eumenides, the chorus of Furies were so frightening in appearance that they caused young children to faint, patriarchs to urinate, and pregnant women to go into labour.  His plays were written in verse, no violence is performed on stage, and the plays have a remoteness from daily life in Athens, either by relating stories about the gods or by being set, like The Persians, in far-away locales. Aeschylus's work has a strong moral and religious emphasis. The Oresteia trilogy concentrated on man's position in the cosmos in relation to the gods, divine law, and divine punishment.  Aeschylus's popularity is evident in the praise the comic playwright Aristophanes gives him in The Frogs, produced some half-century after Aeschylus's death. Appearing as a character in the play, Aeschylus claims at line 1022 that his Seven against Thebes "made everyone watching it to love being warlike"; with his Persians, Aeschylus claims at lines 1026-7 that he "taught the Athenians to desire always to defeat their enemies." Aeschylus goes on to say at lines 1039ff. that his plays inspired the Athenians to be brave and virtuous. CANNOTANSWER
