Final answer:
The claim that Jokasta uses the word 'dystanos' to refer to her child and Oedipus is false. Instead, the play 'Oedipus Rex' by Sophocles deals with the reactions of Jokasta and Oedipus upon learning the truth about Oedipus' tragic fate.
Step-by-step explanation:
The assertion that Jokasta uses the word dystanos to refer to her exposed child and to her husband Oedipus as the mark of her acceptance of the truth is false. In Sophocles' tragedy 'Oedipus Rex', the term dystanos is not specifically used by Jocasta as an acknowledgment of the horrific truth that Oedipus, her husband, is also her son. Instead, the play details Jokasta's and Oedipus' reactions to the revelations of Oedipus' birth and the prophecy that he would kill his father and marry his mother. Once the truths are revealed, Jokasta is overwhelmed by the reality and the fulfillment of the prophecy, and she ultimately takes her own life. Oedipus, distressed by his actions and the truth of his identity, blinds himself and abdicates the throne, all in accordance with Greek tragedy's theme of fate and the unavoidable nature of prophecies.
