Mystery cults are one of the most intriguing areas of Greek and Roman religion. In the nocturnal mysteries at Eleusis, participants dramatically re-enacted the story of Demeter's loss and recovery of her daughter Persephone; in Bacchic cult, bands of women ran wild in the Greek countryside to honour Dionysus; in the mysteries of Mithras, men came to understand the nature of the universe and their place within it through frightening initiation ceremonies and astrological teachings.
