Intelligence, Communication, and Learning
Mercury is the Messenger of the gods, and in many esoteric traditions is one of the most important mythical figures, as he brings wisdom as messages as well (Thoth and Hermes share the same associations). Mercury is also a clever figure, and so is the god of cunning and thought. His planet, therefore, is the same, and is also the Ruler of the Sun Signs of Gemini and Virgo. Mercury is the planetary manifestation of our ability to think on a higher plane, and therefore our ability to use logic and to speak with others.
Mercury is also associated with the intellect and communication, combining Gemini and Virgo. Mercury is associated with writing and teaching as well, and the imparting of knowledge between generations. It is generally a very Airy planet, though it’s Airy aspects are often applied to Earthly uses (such as to deceive and use cunning), making Mercury similar to the Prince of Disks or the Princess of Swords in the Tarot. In its association with intellect, logic, and reason, Mercury also represents learning and our ability to do so.
