Anne McElvoy talks to the poet Simon Armitage about his dramatisation of The Last Days of Troy. His play, based on Homer's epic, reveals how cycles of conflict and revenge, pride and self-deception continue throughout history. Greek myth is at the heart of a new opera, Thebans, in which the playwright and poet Frank McGuinness draws on the tragedy of the mythical monarch Oedipus and his daughter Antigone. Natalie Haynes explores what happens when troubled teenagers become enthralled by Greek tales of cruel fate and bloody revenge in her debut novel, while Kenan Malik goes on a quest for a moral compass.
