In Wiccan tradition, Aradia was the daughter of Diana and Lucifer. She was a goddess of witchcraft, and was said to have taught witches their craft.
Etymology of the name: Aradia comes from the name Herodias, a witch goddess that was supposedly worshipped since the Middle Ages. This form of the name comes from an 1897 book entitled Aradia: The Gospel of the Witches (by Charles G. Leland).
