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.

In the Greek tradition, Mars or Aries was the god of war. Although it also symbolizes the elder brother in the cosmic family, it is more likely to be associated with declared enemies or adversaries. Mars morphology is typically virile, angular, and athletic and corresponds to aggressive, domineering, masculine behavior. Likewise, Mars is usually associated with rage, its resultant brutality, and male destructiveness and domination. Psychologically, Mars figures in any situation of conflict, opposition, and confrontation. Martian symbolism intervenes to separate, oppose, and decide and corresponds to duels, war, and any situation in real life which involves confronting an obstacle. Individuals who are greatly influenced by Mars are typically direct and straightforward—either unabashedly extroverted or furiously introverted. They are extremely active and extremely emotive. Their purpose in life seems to be inextricably mingled with a combat against an unacceptable situation, a challenge which they either issue or are forced to accept.

Pluto, the planet of transformation, rules the sign of Scorpio, the sign of death, redemption, and divine mysteries. Pluto’s energy is mysterious, and its discovery in 1932 associates it symbolically with the creation of the nuclear bomb and the development of psychoanalysis. In ancient mythology, Pluto was considered to be associated with all the aspects of the underworld – Hades, the Greek name for Pluto, was the god of shell. Today, the underworld is synonymous with the Mafia, and the two share many characteristics. Pluto occupies an important place in the horoscopes of great mystics and spiritual beings, as well as in the theme of certain dictators and tyrants, among them the most ruthless and greedy for power. On the psychological level, Pluto corresponds to the transmutation of instinctive energies into energies which are accessible consciously by the individual’s ego. This transmutation, which is never completely controllable, induces a power complex. On the social level, it might be symbolized by the nuclear disaster, the failure of Western man to master the energy of the atom – a power complex gone awry. On the individual level, Pluto is expressed either in a “power complex,” in which instinctive energy is completely transmuted into a personal resource, or as a “failure complex,” in which certain inhibitions prevent the instinctive energy from being transmuted.
