'Aeschylean' originates from the name 'Aeschylus,' a Greek tragedian, where 'Aeschylus' referred to the playwright known for his dramatic works.

'Aeschylus' transformed into the English adjective 'Aeschylean' to describe things related to or characteristic of Aeschylus.

Initially, it referred specifically to the works of Aeschylus, but over time it evolved to describe anything reminiscent of his style.
