Iocasta

Iocasta is a Latinized form of the Greek name Iokaste, more commonly known as Jocasta. In Greek mythology, this name belongs to the tragic queen of Thebes, wife of King Laius and later unwittingly of her own son, Oedipus. The original Greek name Ἰοκάστη (Iokástē) appears in ancient sources, sometimes with the variant Epicaste (Ἐπικάστη). Her story is central to Sophocles' plays Oedipus Rex and Antigone, as well as to the broader Oedipus cycle.

Mythological Role

According to myth, Jocasta was the daughter of Menoeceus, a descendant of Cadmus, the legendary founder of Thebes. She was a member of the city's ruling class and became queen through her marriage to Laius. A prophecy warned that Laius would be killed by his own son, so when Jocasta gave birth to Oedipus, Laius ordered the infant to be exposed on Mount Cithaeron. However, the baby was rescued by a shepherd and raised by the childless king and queen of Corinth. Years later, Oedipus unknowingly killed his father on the road to Delphi and, after solving the Sphinx's riddle, became king of Thebes and married the widowed queen, Jocasta—his mother. When the truth was eventually revealed, Jocasta hanged herself, and Oedipus blinded himself.

Cultural Impact

The name Jocasta (and its Latinized form Iocasta) has been used in various artistic and literary works beyond classical antiquity. In astrology, the name is associated with the main belt asteroid 899 Jokaste, discovered in 1918. The tragedy of Jocasta has also inspired modern psychological terminology, such as the "Jocasta complex," a Freudian term describing a mother's inappropriate sexual attachment to her son. The story remains a staple of Western theater and is frequently reinterpreted in drama and opera.

Note: The name Iocasta (spelled with an "I") reflects the Latin rendering of the Greek name, whereas the more common English form today is Jocasta. The Greek original Iokaste is also adopted as a modern variant.
