The Goddess within Wicca is mostly known as the Triple Goddess: Maiden, Mother & Crone. She is all powerful and strictly a female energy, and the three aspects represent different kinds of her energy.
The concept of the Great Goddess as The Triple Goddess, young woman (Maiden), birth-giving matron (Mother), and an old woman (Crone), dates from the earliest ages of mankind. (These attributes were also ascribed to the three phases of the moon; the Maiden, which corresponds to the new moon; the Mother, which corresponds to the full moon; and the Crone, which is the waning moon. These aspects have been used for centuries by many civilizations.) This concept was embraced by many different mythologies from many different parts of the world. The Vikings had the Norns (Urdu/Verdandi/Skuld), the Romans had the Fortunae (Concordia/Salus/Pax), the druids had Diana Triformis, the Greeks had the Moirae, Graeae, Horae, etc.
The Maiden aspect represents enchantment, inception, expansion, the female principle, the promise of new beginnings, youth, excitement, and a carefree erotic aura. She is innocent in some ways, but also a seductress who recognizes the power of her sexuality. Maiden goddesses include: Anatha, Brigid, Nimue, Kore, Persephone, Gerd, Caer, Blodeuwedd. Her traditional color is white.
The Mother is ripeness, fertility, fulfillment, stability, and power. Mother is ripe, full-breasted, at the peak of her womanly powers. She is the one who tenderly rocks the baby, but she is also the lioness who hunts to feed her offspring and will fight to the death to protect them. Mother goddesses include: Aa, Ambika, Anahita, Asherah, Ceres, Coatlicue, Danu, Demeter, Hathor, Ishtar, Isis, Lakshmi, Luonnotar, Nintu, Sheng-Mu. Her traditional color is red.
The Crone is wisdom, retrenchment, repose, and compassion. She is old age, experience, accumulated wisdom and death. She is the gateway to Death, and the guide to Rebirth. Crone goddesses include: Annis, Baba Yaga, Cailleach, Greine, Hel, Maman Brigitte, Oya, Sedna, Skuld, Takotsi, Toci. Her color is black.
Goddesses who embody the triple aspect within themselves include: Brigid (Ireland/Celtic), Carmenta or Carmentis (Roman), Hekate or Hecate (Greek/Anatolia), Helice (Greek), Kali (India), the Morrigan (Ireland/Celtic).
The Goddess has many names, most say each name refers only to one aspect of the Goddess and her being or power. I will make a separate post on this.
