The African gods are not the only ones relegated to evil. Christians did the same thing with Pan and other Greek gods and goddesses. They even use his depiction of horns and hooves as the model for the devil. And the word devil comes from the Sanskrit word Deva, meaning a shining one.
Also, the pagans, those women practicing medicine and woman medicine suffered the same persecution, if not worse, by the hands of the Church.
When I lived in Cameroon, working with the Peace Corps, a fellow volunteer had a doll made in her likeness by a jealous wife of a chieftain. She had a medicine man destroy it.
Thank you for the article. Cheers.
