Although decans or decanates are no longer used, each sign can be divided into three ten-sector segments known as decans or decanates. The sign ruler rules the first decanate, which is said to be most emphatically of its own nature. In the same triplicity, the planet controlling the next sign sub-rules the next decanate. In the same triplicity, the final decanate is sub-ruled by the next in succession.
While a sign’s element and modality are sufficient to characterize it, they might be grouped to reveal its symbolism. Personal signs are made up of the first four signs: Aries, Taurus, Gemini, and Cancer. The group of interpersonal signs is made up of the next four signs: Leo, Virgo, Libra, and Scorpio. The transpersonal signs are Sagittarius, Capricorn, Aquarius, and Pisces, the last four signs of the zodiac.
Dane Rudhyar discussed the tropical zodiac fundamental factors, which are covered in the RASA School of Astrology’s curriculum. The tropical zodiac, as opposed to the sidereal zodiac, is the zodiac of seasonal variables (constellation factors). The fundamental seasonal elements are determined by the shifting light-dark ratio throughout the year. The first consideration is whether the selected time falls during the half of the year when daylight increases or during the half of the year when darkness increases. The second consideration is whether the chosen date comes during the half of the year when there is more daylight than darkness, or during the half of the year when there is more darkness than daylight. The third factor is the season in which the chosen time falls, which is determined by the first two factors. Thus
- The winter season is when the amount of daylight increases and the amount of darkness decreases.
- The spring season is when the amount of daylight increases and the amount of darkness decreases.
- The summer season is when the amount of daylight is greater than the amount of darkness.
- The autumn season is marked by an increase in darkness, with more darkness than daylight.
Is there any truth to the zodiac signs?
Ancient astronomers envisioned the zodiac constellations as having unique patterns that reflect the shapes of animals and humans. As illustrated, the zodiac constellations form an imagined belt in the sky that stretches about eight degrees above and below the ecliptic plane.
