Some stories never lose their grip on us. They compel us to recast them again and again, in different ways. This goes back to before the birth of writing: For every myth preserved in written form there were, in swirling echoes around it, variations of the story that did not survive—but are just as true.
A story of sufficient power can wear many faces. The Greek tragedians understood this, drawing endlessly on their mythology to give us alternate versions of Oedipus, of Iphigenia, of Electra. That tradition, of recasting powerful stories, endures to this day.
