discuss the ending of the play in terms of 'tragic enlightenment"

The playwright never intends for us sympathize with Medea, as we do with other tragic heroes (think Oedipus), but rather to understand Medea and react to her decisions emotionally. The final conversation between Jason and Medea should invoke our pity, all while shocking and terrifying us. Thus, it is only when we understand the primitive forces behind her actions that tragic enlightenment of her primitive behavior allows us pity.
