Tragedy (from the Greek: ÏÏÎ±Î³á¿³Î´Î¯Î±, tragÅidia) is a form of drama based on human suffering that invokes in its audience an accompanying catharsis or pleasure in the viewing. For a work to be tragic, it need not have a tragic ending. 2  Although Aristotle says that catharsis (purgation of emotion) should be the goal of tragedy, this is only an ideal. 3  In conformity with the moral codes of the period, plays should not show evil being rewarded or nobility being degraded.
The first plays were performed with just one actor (called a protagonist) and a chorus of people who helped him to tell the story. However, throughout the 5th century BC playwrights continued to innovate. The playwright Aeschylus added a second speaking role, called the antagonist, and reduced the chorus from 50 to 12. His play 'The Persians', first performed in 472 BC, is the oldest surviving of all Greek plays. His pupil, Sophocles went on to add a third actor, while Euripides added both a prologue, introducing the subject of the play, and the deus ex machina, a divine figure who wrapped up any loose ends at the close.
