Iphis

Iphis (strength) In Greek and Roman mythology, daughter of Telethusa of Crete and Ligdus. Iphis was raised secretly as a boy by her mother because her father, Ligdus, wanted only male children and would have killed her had he known she was a girl. When Ianthe, a young girl, fell in love with Iphis, the goddess Isis changed Iphis into a man. Ovid’s Metamorphoses (book 9) records the myth.
