This play is actually made up of 3 different plays, a trilogy: The Homecoming, The Hunted, and The Haunted. To begin, then, let's define "tragedy": "a dramatic composition, often in verse, dealing with a serious or somber theme, typically that of a great person destined through a flaw of character or conflict with some overpowering force, as fate or society, to downfall or destruction" (www.dictionary.com). In these 3 plays, we have characters that all deal with tragedy, including suicides and murder. Tragic characters have one distinct flaw, and the characters in these 3 plays are no exception. For example, Brant's tragic flaw is his obsession with revenge, which leads him to murder, so this play is definitely a modern tragedy. Also, the play is based on a Greek tragedy. eNotes states: "In the play, he adapts the Greek tragic myth Oresteia to nineteenth-century New England" (eNotes).
