Tiresias

In Greek mythology, Tiresias (taɪˈriːsiəs; Teiresías) was a blind prophet of Apollo in Thebes, famous for clairvoyance and for being transformed into a woman for seven years. He was the son of the shepherd Everes and the nymph Chariclo. Tiresias participated fully in seven generations in Thebes, beginning as advisor to Cadmus himself. Eighteen allusions to mythic Tiresias, noted by Luc Brisson, fall into three groups: the first recounts Tiresias' sex-change episode and later his encounter with Zeus and Hera; the second group recounts his blinding by Athena; the third, all but lost, seems to have recounted the misadventures of Tiresias. Like other oracles, how Tiresias obtained his information varied: sometimes, he would receive visions; other times he would listen for the songs of birds, or ask for a description of visions and pictures appearing within the smoke of burnt offerings or entrails, and so interpret them. Pliny the Elder credits Tiresias with the invention of augury. On Mount Cyllene in the Peloponnese, as Tiresias came upon a pair of copulating snakes, he hit the pair with his stick. Hera was displeased, and she punished Tiresias by transforming him into a woman. As a woman, Tiresias became a priestess of Hera, married and had children, including Manto, who also possessed the gift of prophecy. After seven years as a woman, Tiresias again found mating snakes; depending on the myth, either she made sure to leave the snakes alone this time, or, according to Hyginus, trampled on them. Either way, as a result, Tiresias was released from his sentence and permitted to regain his masculinity. This ancient story was recorded in lost lines of Hesiod. In Hellenistic and Roman times Tiresias' sex-change was embellished and expanded into seven episodes, with appropriate amours in each, probably written by the Alexandrian Ptolemaeus Chennus, but attributed by Eustathius to Sostratus of Phanagoria's lost elegiac Tiresias. Tiresias is presented as a complexly liminal figure, mediating between humankind and the gods, male and female, blind and seeing, present and future, this world and the Underworld.
