Oedipus Rex, also known by its Greek title, Oedipus Tyrannus (Ancient Greek: Οἰδίπους Τύραννος, pronounced [oidípoːs týrannos]), or Oedipus the King, is an Athenian tragedy by Sophocles that was first performed around 429 BC.[1] Originally, to the ancient Greeks, the title was simply Oedipus (Οἰδίπους), as it is referred to by Aristotle in the Poetics. It is thought to have been renamed Oedipus Tyrannus to distinguish it from another of Sophocles's plays, Oedipus at Colonus. In antiquity, the term "tyrant" referred to a ruler with no legitimate claim to rule, but it did not necessarily have a negative connotation.

The name "melancholia" comes from the old medical belief of the four humours: disease or ailment being caused by an imbalance in one or more of the four basic bodily liquids, or humours. Personality types were similarly determined by the dominant humor in a particular person. According to Hippocrates and subsequent tradition, melancholia was caused by an excess of black bile, hence the name, which means "black bile", from Ancient Greek μέλας (melas), "dark, black", and χολή (kholé), "bile"; a person whose constitution tended to have a preponderance of black bile had a melancholic disposition. In the complex elaboration of humorist theory, it was associated with the earth from the Four Elements, the season of autumn, the spleen as the originating organ and cold and dry as related qualities. In astrology it showed the influence of Saturn, hence the related adjective saturnine.
