[[Tiresias]] was a priest of Zeus, and as a young man, he encountered two snakes mating and hit them with a stick. He was then transformed into a woman. As a woman, Tiresias became a priestess of Hera, married, and had children, including [[Manto (mythology)|Manto]]. 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 [[Gaius Julius Hyginus|Hyginus]], trampled on them and became a man once more.<ref>Hygini, ''[[Gaius Julius Hyginus#Fabulae|Fabulae]]'', LXXV</ref>
As a result of his experiences, Zeus and Hera asked him to settle the question of which sex, male or female, experienced more pleasure during [[Sexual intercourse|intercourse]]. Zeus claimed it was women; Hera claimed it was men. When Tiresias sided with Zeus, Hera struck him blind.<ref name=":3" /> Since Zeus could not undo what she had done, he gave him the gift of prophecy.
