Mercury’s astrological domain is the area of mental process and communications in all forms. It rules early environment, knowledge and learning and in the business world it represents sales or skilled trades. In mythology, Mercury is usually portrayed as a youthful, quick-witted trickster but above all as a scribe and master of intellectual pursuits. The placement of Mercury in a person’s chart shows how they think and use rational thought and logic. A person’s voice, the way they speak and the language they use to express themselves is determined by Mercury. It is the dual ruler of both Gemini and Virgo. Through Gemini mental agility and expression are focal, as symbolised by the Twins and through Virgo the practical and analytical organiser as symbolised by the Virgin. Although the energy of Mercury is ever changing its purpose is to provide the facts. So, as the expression goes, “don’t shoot the messenger”.
