The Triple Goddess is symbolized by a full moon with a waxing crescent to its left and a declining crescent to its right. This is the second most common symbol in Neopagan and Wiccan culture, behind the pentagram. Neopaganism and Wicca are 20th-century incarnations of an old form of nature worship.
They’re also known as earth religions or natural faiths. The Triple Goddess is compared to the Celtic Mother Goddess by Neopagans and Wiccans; the full moon represents the woman as a nurturing mother, while the two crescent moons represent the maiden and the crone.
