Aeschylus

Aeschylus is the first of the three great Greek tragedians, the others being Sophocles and Euripides. Aeschylus’ work has a strong moral and religious emphasis. Besides the literary merit of his work, Aeschylus’ greatest contribution to the theater was the addition of a second actor to his scenes. Previously, the action took place between a single actor and the Greek chorus. Aeschylus is known to have written over 70 plays, seven of which are extant. —The University of Adelaide
