She is usually depicted as having a globe in her left hand and a peg in the right, and her foot on a turtle, symbol of silence. She is able to foretell the future by the position of the stars. She is often associated with Universal Love and the Holy Spirit. She is dressed in a cloak embroidered with stars and keeps her eyes and attention focused on the Heavens. Those who are most concerned with philosophy and the heavens are dearest to her.
