In all his plays Sophocles interweaves archaic law with the (chthonic) cult of the underworld.Both these elements are concepts of a mythical past represented by Orphism – the religion characterized by faith in the immortality of the soul, by the Orphic and Eleusinian Mysteries as well as by the first philosophical and religious doctrine of the Pythagorian philosophers. In Sophocles’ tragedies “Aias”,” Antigone”,” Philoctetes” and” Oedipus the King”, we can investigate the close bonds of the tragic hero to the Under World and the chthonic deities. As a matter of fact the death of Aias can be interpreted as a ritual repetition of the sacred drama of the Orphic Dionysos / Zaghreas. The entire second part of the tragedy is devoted to the conflict concerning the deceased and his burial. The play ends with the ceremonial burial of the hero. The deification of the man who overcomes death, an interpretational axis in Sophocles , in our opinion, is completed in Oedipus the King, by the hero’s Assumption at the end of the play.
