According to Greek mythology and the Roman poet Ovid, who wrote about transformations in his Metamorphoses, Iphis (or Iphys) was the daughter of Telethusa and Ligdus in Crete. Ligdus had already threatened to kill his pregnant wife's child if it wasn't a boy. Telethusa despairs, but is visited in the middle of the night by the Egyptian goddess Isis, attended by Anubis and Apis, who assures her that all will be well.

When Telethusa gives birth to Iphis, she conceals her daughter's sex from her husband and raises her daughter as a boy. Iphis falls in love with another girl, Ianthe. Iphis is deeply in love and prays to Juno to allow her to marry her beloved.

When nothing happens, her mother Telethusa brings her to the temple of Isis and prays to the goddess to help her daughter. Isis responds by transforming Iphis into a man. The male Iphis marries Ianthe and the two live happily ever after. Their marriage is presided over by Juno, Venus, and Hymenaios, the god of marriage
