Mercury: Rulership, Exaltation, Detriment and Fall


Mercury is the closest planet to the Sun and we can often observe it with a naked eye before sunrise or after sunset. It is named after the Roman god of communication, the messenger of gods, who is the equivalent to the Greek Hermes. Astrologically, the planet is ruling intellect and information, thus being responsible for a lot of things connected with the human mind. Indeed, the planet’s placements and influences influence the flow of data and speech; yet he is also ruling their misusage.

Mercury is the governor of logic and reason, thought, and opinion. He is the vital planetary influence that made humankind evolve to a conscious being, while also is responsible for transportation. The planet has very quick and hasty characteristics, which when used appropriately can create a bright mind.

We should, therefore, notice that an afflicted Mercury can be the source of mental and neurologic problems.

Mercury rules the signs of Gemini and Virgo. Diurnal Mercury is considered the ruler of Gemini, while nocturnal of Virgo. In addition, Mercury is responsible for the 3rd and 6th houses and makes a full circle around the zodiac in approximately 1 year (it always depends on when it has its retrograde motion). We always observe him somewhere very near the Sun, as his orbit is way closer to the Sun than the Earth’s. In fact, most of the time we cannot observe him in the sky due to its closeness to the Sun. Mercury spends less than one month in every sign, preceding or following the Sun’s movement. Once per 4 months, the planet turns retrograde for about 3 weeks. He is exalted in the sign of Virgo, in fall and weak in Pisces, while operates rather toughly in Sagittarius where it is in detriment.

The passage of the planet through any house brings mental focus on the house’s matters, speeds up decisions and generally makes us invest our intellect towards the direction the house indicates. Of course, the planet’s transits do not last long; yet their influences can trigger quite a lot of events. After all, it is our conscious thought and dedication towards a subject that always brings change. The more we think about something, the more we act towards that direction; thus a Mercurial transit usually becomes the predecessor of actions. On the other hand, transits of slow-moving planets to natal Mercury can signify long-lasting changes concerning the way we perceive reality and think; therefore it always depending on the aspect and the transiting planet to see what kind of permanent or temporary changes will come to our mind.

Mercury rules contracts, negotiations and even mischief through them. He is responsible for short trips, and transportation in general. The planet is the governor of all messages and the whole procedure of their transfer from the source to the receiver. He rules all short types of communications, your neighbors that may be gossiping behind your back, your daily mail -including even the spam you receive. In addition, the planet is responsible for books and written text, friendly meetings and the news. Basic education is also a part of Mercury’s realm, as is also teaching on a basic level.

A strong Mercury by placement or aspects can make someone a brilliant mind, being able to absorb a lot of information. Frequently, this ability comes paired with the exact opposite one, to excel in transmitting information towards others. The planet can make someone a programmer, a writer, or direct to other professions that are connected with data filing and information process.

Mercury is the inner power that will make you strive to develop your ideas, the force that will drive you to explore the world around you. It feeds your natural curiosity to discover and understand so that you later use your obtained knowledge consciously. Of course, he can also be responsible for misunderstandings, lies and corrupt information. Difficult aspects to Mercury may show over-thinking or mental challenges, obsessions considering specific types of information and misuse of the Mercurial gifts in general. We should not forget that Mercury as a god is also the protector of thieves and swindlers. Indeed, non-violent crimes that are used with the aid of speech, contracts, and misinformation is a dark side of the planet’s influence.

Due to his connection with the 3rd house, the planet governs our siblings, while also a lot of other things connected with our childhood. The progress of developing our intellect through school and even playing in the neighborhood is a Mercurial activity.

As a planetary force, Mercury requires from us to become processors of the inflowing information in order to put it in a logical inner system and use it. Whoever is more receptive to the planet’s energy will eventually have larger benefits from it, and will develop stronger intellectual skills. Those who tune in with its frequencies will have more accurate results through their logical thinking and will be able to develop their wisdom quicker.
