Anouilh's Antigone, 4

motivation of characters:

Each tragic character is motivated by something different. Oedipus is motivated by his curiosity to know the truth about his past. Antigone in Sophicles' version is motivated by her commitment to her family in honoring them and dying with them. This motivation is similar to that of Antigone in Anouilh's version. However, Medea is motivated by her own emotions, her lust for revenge and her desire to show her dominance over Jason and the city.

fate is what controls the characters:

Oedipus is the obvious example of fate; he cant alter his foreseen future. Medea on the other hand seems to have that power but regardless of her actions she is still destined to a life of pain and grief. Both Sophicles' and Anouilh's Antigones are controled by a diffrent kind of fate. They make the choice to bury their brother and there for are destined to die but they see no other alternative and believe it is their duty to go through with it. There isn't any other option so in that sense they are controled by a fate outside of their control.
