#Hekate is sometimes said to be a virgin goddess, but 2 accounts make #Hermes her lover, one of which makes him her first:
"Hekate, who as legend tells, by the waters of Boebeis [a lake in Thessaly] laid her virgin body at Hermes' side."
Propertius, Elegies 2, 1st century CE
Hekate is the goddess of magic, witchcraft, the night, moon, ghosts and necromancy. You may know her name from William Shakespeare's MacBeth, where the three witches invoke her.
