Friday is dedicated to the planet Venus, personified as the Roman goddess of love. The Nordic goddess Freya, the patroness of women of power, gave her name to this day. In Norse mythology, she presides over the Valkyries, the winged goddesses who bring fallen heroes to Valhalla, the realm of the gods. Renowned for her beauty, Freya is often called “the Fair One.” Any spells or charms relating to matters of the heart are appropriate for this day, as well as divination for inspiration in the arts. The influence of Venus is strong on Fridays and makes this day suitable for issues dealing with love, comfort, and the fulfillment of desire.
