The Four Directions as the Foundation of Western Astrology

Summary: Astrology originated when humans became attuned to the repeating astronomical patterns of the annual cycle. The yearly cycle of sunrises and sunsets against the horizon offered humanity the opportunity to make the seasonal predictions necessary for successful agriculture. The naming of the critical stations [positions/frequencies] of the year, the equinoxes [when sun crosses equator, making night & day of equal length in all parts of earth] and solstices [sun standstill] and the analogy with the diurnal [daily] cycle, constitutes a first order of astrology. On a global level, the symbolism of the four directions, the first astrology, has served as a foundation for more elaborate intellectual systems. This shared symbolism is the foundation of the world's astrological and divinatory systems.
Astrology's biological basis and social basis may be similar. As life evolved on this planet it utilized astronomical rhythms to regulate bodily functions. Eventually, these rhythms were internalized. To use the terms of astrobiologists, exogenous cycles that required an external agent, became endogenous or internalized cycles. The same thing seems to have occurred as early humans struggled to make sense out of the surrounding world and ultimately create culture and civilization. The external facts of repeating astronomical cycles offer various kinds of security, ones that can serve as frameworks around which human culture and social systems can be built.
Calendars, based on astronomy, organized early humanity in matters of TIME. Maps and directions organized them with SPACE. Both incorporate the rhythms of the sky. Symbolic thinking, which preceded rational thought as a means of communicating or transmitting information over great expanses of time, explained these connections between man and nature. Astrology is a kind of conscious internalization or learning from the external environment that has become the foundation of much of who we are, both as individuals and as a society.
The zodiac used by most Western astrologers today (the tropical zodiac), has become a symbol of astrology itself. It is, in essence, a symbolic sequence of stages in the year that is framed by the four directions. Each quarter of the year, the time between each of the four main stations of the annual cycle, is trisected to produce three signs. In this scheme, Aries is the sign of the east and springtime. Its opposite, Libra, is the sign of the west and autumn. The first degree of these signs marks the vernal [spring] and autumnal [autumn] equinoxes. The summer solstice begins the sign Cancer, which is a sign of summer, and is also a sign of the south. Capricorn, then, is the sign of winter and of the north.
Aries, Cancer, Libra, and Capricorn are, therefore, the KEY signs of the directions, and quite possibly the source of the scheme of the elements. Aries is the sign of spring, and therefore by analogy, the sign of sunrise. It is the sign of emergence and the birth of the sungod. It is a fire sign, and some would say, the source of the other two fire signs. From Aries, rays extending in equal arcs of 120 degrees will designate the beginnings of the other two fire signs, Leo and Sagittarius. Fire, according to this logic, is the element of the East.
Libra is the sign of autumn, the sign of sunset, and the direction West. It is an air sign, suggesting that it is the primary sign of the element air. The same approach can be taken for Cancer and Capricorn. These two signs might be looked on as origin points for the other elements, water and earth. Taking this directional foundation for quaternary [spring, summer, autumn, winter] symbolism further, links can also be made with the four humors [former belief in four body fluids held responsible for one's disposition] or temperaments. The temperaments were a conceptual framework for ancient healers, an ancient psychological typology, and in modern times, the foundation of Jung's four functions. The choleric temperament is hot, easily aroused. This sounds like fire. The melancholic temperament is sad and depressed. Perhaps this is earth. The sanguine temperament is confident and optimistic. This may be air. The phlegmatic temperament is slow and impassive. This may be water. While the connections are somewhat blurred, it is possible that these foundational concepts (not to mention the four archangels, the four evangelists, and four tarot card suits) all derive from the four directions and their midpoints, and ultimately from the astronomical motions of the Sun.(5) Astrology lies deep within the fabric of culture.
