I'll also have more on visualisation once I have my book of shadows back from my old house as I'm halfway from one place to the other to the other again.
Funnily enough, Sophia is not mentioned very often and sits on the fence between Christian and Pagan religions. Originally as a Gnostic goddess, the 'Lady of Divine Wisdom' takes her name from the Hebrew 'Hochma' or 'Wisdom.' In Greek, Sophia literally translates to 'Wisdom.' She appeared in 'The Wisdom of Solomon' by an Alexandrian Jew in approx 30BC, was present at creation and was God's bride... certainly not something which is well known as she is seen in the image below from the Sistine Chapel holding up God's arm and supporting his work. The Seal of Solomon itself is said to go back to the Bronze Age which is a part of Kabbalistic magickal tradition and has been used in Hermetics (alchemy), containing the Star of David.

She is venerated as the goddess of truth, wisdom and the occult mysteries... or apparently the occult mysteries according to Fiona Horne. She is depicted with a book in her left arm and a dove coming out of her heart. So how at the end of this can we connect her to the 'occult mysteries'? Is it because of her links to the book of Solomon which leads us to the Kabbalah and Hermetic traditions, or because she is so relatively unknown except for in Eastern Europe?
Another source leads us to some interesting information (via Northernway):
So perhaps she was another Goddess to be omitted from the majority of Western Christian tradition like Lillith? How and why she is linked to Hecate is unclear but certainly interesting.
