Mystery Cults and Gender?
What is the relationship between cultural origins (East/West, Greek/Asian) and gender of followers? All linked to fertility?
Mithras – primarily male followers
Dionysus – bacchae/maenads
Cybele & Attis
The Eleusinian Mysteries–Demeter and Persephone
And the Jesus cult? Look at it in terms of early martyrs, e.g., St. Perpetua, as well as accounts of gatherings.
