Wiccan worship includes worship of The Great Goddess along with the [Horned God]?. There has been some association of the Wiccan Goddess with the Greco-Roman goddess Aradia?, also with [Mother Earth]? (or [Mother Nature]?), and with the moon. She may also be refered to as 'Queen of Heaven' . The Great Goddess is believed by many Wiccans to have been worshiped in a universal pre-historical matriarchial? religion. The Goddess is worshipped sometimes by worshipping her different aspects, represented by individual goddesses like Isis?, Kwan Yin, Kali, Pele? or Athena. The yoni or vulva may also be revered as an aspect or symbol of the Goddess.
