Is Oedipus the king the same as Oedipus Rex?

Answer 1

Yes. In many ways. Oedipus Rex follows many of the same tragic concepts that Star Wars borrows from in the prequels, and the redemtive death of Oedipus in Oedipus at Colonus is similar to Anakin's death in episode VI. Also, on a more superficial level, there are incestual themes with Luke and Leia, though they don't know that they are siblings, as with Oedipus' relationship with his mother. The premonitions Anakin faces can also be likened to Tiresias' prophecies, both of which reveal painful truths to the hero.

Answer 2

Luke was not intentionally given up by his father; Oedipus was. Luke did not have intercourse with his mother; Oedipus did.

Answer 3

Yes
