The Mount of Mercury
Mercury, the fastest of the gods, was their winged-foot messenger, and he ruled commerce and business. The mount at the base of the Mercury (small or pinky) finger controls your love for communication, expressiveness, and travel, as well as your abilities in business, teaching, and practical matters. Mercury also rules the sciences, healing arts, and even close relationships with friends and children.
A well-defined mount of Mercury shows that you are a speedy person with many interests, a good communicator, and a confidant. You are versatile and flexible, and you respond well in emergencies or when action is needed. You may make a good salesperson or businessperson, public speaker, or politician. You love family life, are skilled at number games, and are good at observation, so you can read others easily.
What if a finger mount is not clearly at the base of any particular finger, but is between two of them?
In that case, the characteristics it displays may be interpreted as a combination of the qualities of those two fingers.
Development of the Mercury Mount
Too large a Mercury mount, and you talk too much, perhaps not always truthfully, and may use your gift to influence others wrongly. In any case, you will use your communications skills to advance in life.
On the other hand, a flat mount can mean you are a quiet or shy person, one who does not easily understand what is going on around you, or one who is too caught up in your life with little interest in others. It may be hard for you to communicate with a mate. You may also be impractical and confused. Many people with an underdeveloped mount of Mercury aren't successful in science or business.
If the Mercury mount veers toward Apollo, look for an artist who understands the business of art, such as a gallery owner; someone who enjoys the little rituals of life and carrying them out graciously; or someone who has a strong sense of curiosity and many areas of interest. This person will be able to communicate creatively and approach any subject in a general way. If, on the other hand, your mount of Mercury veers toward the edge of the hand, you are the ultra-Mercury — fast-thinking, fast-talking, fast-acting, changeable, and totally into what you are doing.
