Hermaphroditus
Ἑρμαφρόδιτος
The son of Hermes and Aphrodite — even his name fuses the two gods.
The spring nymph Salmacis fell for him and, clinging to him, prayed never to be parted from him.
The gods granted the wish literally, and the two became a single body.
The word for a being with the traits of both sexes comes from him.
