Comedy: The first comedies were mainly satirical and mocked men in power for their vanity and foolishness. The first master of comedy was the playwright Aristophanes. Much later Menander wrote comedies about ordinary people and made his plays more like sit-coms.
Tragedy: Tragedy dealt with the big themes of love, loss, pride, the abuse of power and the fraught relationships between men and gods. Typically the main protagonist of a tragedy commits some terrible crime without realizing how foolish and arrogant he has been. Then, as he slowly realizes his error, the world crumbles around him. The three great playwrights of tragedy were Aeschylus, Sophocles, and Euripides.
