Mercury governs the mind and quickens or intensifies the action of other planets which it forms any aspect with in the horoscope. It furnishes, to a great extent, the vital force necessary for business life; when favorably aspected to Venus and Mars it gives talent for music, art or literary work. One must have Mercury well placed to be a popular and successful orator.
Mercury rules the hands, arms, brain and nervous system, the mouth, tongue, and eyes. Mercury is neutral or sexless, but may be called convertible. If in aspect to Venus or Moon, is feminine; in aspect to Mars or Jupiter would be masculine. Mercury rules in one’s life from the age of four to fourteen years.
