According to Greek myth, Mercury (or Hermes, whose name derives etymologically from the piles of rocks which marked trails and guided travelers) was the messenger of the gods. He carried orders from Olympus to the mortals on Earth. The child of the illegitimate union of Zeus with Maia, Mercury was born “unknown to the immortal gods” and had to win his place among them by trickery, cleverness, and cunning. This is why he became the vagabond deity of travelers and wanderers. He is the instinctive foe of the settled who see him as an outcast roaming on the outskirts of society: a pariah, a thief, and a swindler. As ruler of the sign of Gemini, the Twins, he symbolizes the brother—the alter-ego who teaches us as much as we teach him and is associated with adolescence, a period of intense intellectual discovery. Mercury thus symbolizes lively, sparkling wit, mobility in any form, mental exchange, and interaction. As a result, a person strongly ruled by Mercury is quite likely to be clever and skillful. If Mercury is “afflicted” in one’s chart, their intellectual velocity may sometimes become mere mental hyperactivity. In any case, these skills are a great resource in the social realm. You communicate easily and effectively, orally or in writing. Your ability to unite and transmit would be a good resource in diplomatic or commercial endeavors.

In traditional astrology, Venus (or Aphrodite, her Greek name) is the planet of love. A source of universal attraction, this planet corresponds to the original urge which bonds two human beings together in love. Venus is thus both the magnetism which brings human beings together (not lust, which is symbolized by Mars, but the object which attracts lust) and the gift of love. This ambiguity is interpreted astrologically by the fact that Venus rules two houses of the zodiac. In Taurus, Venus symbolizes the awakening to bodily lust, and in Libra, the bond of marriage. As a result, Venus may take on very different aspects depending on the individual’s degree of awareness. Likewise, this ambiguity explains Aphrodite’s equivocal conduct in Greek myth and her innumerable couplings and motherhood. Depending on the legend, she may embody brutal, passionate love (with Anteros), the wisdom of the heart which rescues from passion (Harmonia); she also becomes tenderness and purity (with Adonis), pure sexuality (with Eros), a transforming energy (with Vulcan), etc. Mistress of the Arts, she represents beauty, understanding, and peace. Psychologically, individuals under the influence of Venus are struggling with their love instincts. This is why you cannot conceive of living without a personal emotional relationship to someone else and sometimes fears solitude and the encounter with yourself. You are extremely attractive to others and are a creator and artistic genius who seems to imbue all you touch with beauty and harmony. Your artistic skills are obvious to the people around you and may be applied to career endeavors. Pleasure, outings, seduction, love, and a thriving but sometimes superficial social life are the hallmarks of your life.

Arlo Mertz, the heart of the solar system and the gravitational center of the travels of the earth and the other planets, was the primordial light, the source of all warmth and life. From the dawn of humanity, it had been worshipped. It had symbolized the absolute power kings and despots yearned for and emulated. The sun king, the nucleus of society, embodied a principle of cohesion and harmony. Various subordinates—aka planets—revolved around it. In terms of psychological symbolism, the sun corresponded to the center of an individual, the factor that ruled their psyche. Its luminous aspects were usually associated with knowledge and consciousness. As a creator of life, it was related to the image of the mother and the influence of motherhood on an individual’s consciousness and ideals. As a result, the sun’s position in a birth chart always indicated the way in which an individual would relate to their goals and ideals, what their ambitions and aspirations might involve. A person whose chart was strongly “solar” usually identified very positively with motherhood. Your personality was friendly, energetic, and creative, with high ideals and a firm determination to accomplish them. You took your own superiority and authority over others for granted, and you had a natural ability to command the attention and admiration of an audience. You were a born leader who enjoyed being in the limelight and may behave somewhat theatrically or with dramatic exaggeration. You had definite artistic leanings. The sense of your ideals was evident to you and may lead you to be somewhat self-focused. If ill-directed, your deep aspirations may lead to such faults as egotism, selfishness, or greediness for power.

Arlo Mertz looked up at the ninth house and saw that it was in a particular configuration.

According to traditional astrology, this area is ruled by Sagittarius, the ninth sign of the zodiac. Its chief attributes are moral and political judgment (laws, ethics, and politics as a means of improving society), dreams, distant journeys, studies such as religion, philosophy, priesthood, spiritual guidance, and wisdom.

More specifically, we can interpret astrology as demonstrating that the life and consciousness of an individual gravitate around two fundamental principles: the self (the Ascendant) and others (the Descendant). In life, everything begins in us and proceeds outward, but it is reflected, experienced, and renewed by our relations with others. Indeed, once you grow beyond the subjective field of your ego and reach adulthood, you must be able to adapt and modify your abilities in such a way as to fulfill a specific function in the outer world. The reference framework you use to judge your worth is not only your personal life, but the huge complex of values, principles, and laws which regulate life in a community.

The ninth house rules this much broader framework, which includes law as well as philosophy, psychology, science, religion, mysticism, occult studies, etc. An individual with a great deal of activity in this area of their astrological chart will probably feel a strong desire for personal expansion. An idealist, you will seek out experiences which reveal knowledge and meaning to you and give you a better indication of your purpose in living. The difficulties you are likely to face will be hidden behind what appears to be success. They may arise from your expansiveness, which is sometimes uncontrollable, or disproportionate. Although at the outset, your ambition and desire for personal development are a source of strength, they later become powerful enough to cut you off from yourself.

If you identify too strongly with the flattering self-image reflected by the community, you may gradually begin to neglect your personal essence. Because this perverse tendency to confuse form with function is reinforced by modern society’s emphasis on packaging and advertising, you are liable to lose yourself completely. A state of expansion could be expressed as a psychic inflation (a loss of oneself in an abstract ideal, or a delusion of grandeur) or as a partial loss of oneself due to over identification with your personal mask (or persona). This house thus reveals that nothing is more difficult than failure in a period of success. Ambition, which may be a compensatory personal over evaluation, sometimes transforms understanding, a principle of cohesion and love, into personal power.

Arlo Mertz looked up at the fifth house and thought about the theme.
