Leucippus, either male or death: a case of sex reversal by divine intervention

The concept of metamorphosis (change of form, structure, or substance) is very frequently encountered in Ancient Greek and Roman literature. One of the most striking types of metamorphosis described in many myths is gender transformation, where a man becomes a woman or vice versa. Herein, we present a case of pubertal gender inversion, the marvelous story of the Cretan Leucippus, which not only inspired many ancient writers but also led to the development of a distinct, local, religious cult. A medical interpretation of the myth, whereby we attempt to establish a diagnosis for this case of heterosexual puberty, is also provided.
