Leucippus of Crete

In Greek mythology, Leucippus (Ancient Greek: Λεύκιππος Leukippos, "white horse") was a young man of Phaistos, Crete. Leucippus was born to Lamprus, the son of Pandion, and Galatea, daughter of Eurytius the son of Sparton. He is notable for having undergone a magical gender transformation by the will of the goddess Leto. Due to his transition from female to male, Leucippus can be considered a transgender male figure in Greek mythology.

His story was included in the Metamorphoses by Antoninus Liberalis. It shares several elements with the myth of Iphis, another female child raised as and transformed into a male from Ovid's Metamorphoses.
