Bona Dea

In ancient Roman religion, Bona Dea ( Latin: [ˈbɔna ˈdɛ.a]; 'Good Goddess') was a goddess associated with chastity and fertility among married Roman women, healing, and the protection of the state and people of Rome. According to Roman literary sources, she was brought from Magna Graecia at some time during the early or middle Republic, and was given her own state cult on the Aventine Hill.

Her rites allowed women the use of strong wine and blood-sacrifice, things otherwise forbidden them by Roman tradition. Men were barred from some of her mysteries and only initiates were given the possession of her true name. Given that male authors had limited knowledge of her rites and attributes, ancient speculations about her identity abound, among them that she was an aspect of Terra, Ops, Cybele, or Ceres, or a Latin form of a Greek goddess "Damia" (perhaps Demeter). Most often, she was identified as the wife, sister, or daughter of the god Faunus, thus an equivalent or aspect of the fertility nature-goddess Fauna, who could prophesy the fates of women.
