The serpent and owl were sacred to her. The serpent is an emblem of life energy and creative impulse. The owl symbol of death and wisdom, and thus Minerva, a goddess of dawn and of wisdom, is also a goddess of death and transformation. Minerva is an incarnation of wisdom in human form, an affirmation that we can use our knowledge and wisdom in pursuit of any goal we choose.

Minerva was Roman goddess of war, wisdom and crafts. In Britain at turn of 1st millennium CE, Minerva was depicted throughout Celtic Britain in both purely Roman fashion and in more abstract Celtic style But in Bath, at temple of Aquae Sulis she becomes "fully equated with a Celtic goddess, Sulis". (1) So as you see as with our earthly Mother according to aspect we are calling on we call on name that matches that aspect of Great Mother.Of The Great Goddess

So call her name when you need protection from warrior mother or wise counsel. Call her by yet another name when you need healing. You can call on her when you need inspiration and a muse to create. She is great mother female side of God.

Anu is considered to be ancestor of all Gods, Tuatha dé Danann, who found themselves obliged to reside in Otherworld when Miled brought Celts to British Isles. She still looks down on us from night's sky where she appears as Llys Don, better known as constellation of Casseopeia. Anu was especially popular in Munster, though her most lasting memorial is a mountain in County Kerry called Dá Chích Anann or "Breast of Anu". The Dane Hills in Leicestershire are also named after her and this area, perhaps a major centre for her cult, is where her memory lives on as Black Annis. This hideous old crone's habit of eating young children was, no doubt, invented by incoming Christians to blacken name of Celtic Goddess. In Christendom, lady usually took on guise of St. Anne, however, in order to smooth path of conversion. This saint's popularity in Brittany probably stems from previous worship of Celtic Goddess there. Anu was also patroness of springs and fountains, hence numerous St. Anne's Wells throughout Britain today. Symbols: Emeralds, Blood, Moonstones
