Astrological sign

Western astrology employs the tropical zodiac which divides the ecliptic into twelve signs of equal length starting at the first point of Aries, which is defined as the point at which the ecliptic (the apparent path of the Sun through the heavens) crosses the celestial equator at the spring equinox. It is important to note that these signs are completely independent of the astronomical constellations after which they were originally named and no longer bear any relationship to them.

Because the calendar is defined by the movement of the Earth around the Sun, and its orbit is very nearly circular, the sign in which the Sun falls on any day of the year is fairly predictable, though it will vary a little due to the effect of the extra day in leap years. These dates are given in the article that deals with each sign individually. To determine the sign in which the moon and other planets fall on any given day, it is necessary to consult an ephemeris or use an astrological computer program which will have a built-in ephemeris; these computer programs make it quick and easy to calculate the natal chart (also called horoscope) so that the astrologer can spend more time interpreting the chart rather than actually calculating it.


Traditional Rulership versus Modern Rulership

In traditional Western astrology, each sign is ruled by one and only one of the planets (note that in astrology, the Sun and Moon are considered planets, which literally means wanderers, i.e. wanderers among the stars). The traditional rulerships are as follows: Aries (Mars), Taurus (Venus), Gemini (Mercury), Cancer (Moon), Leo (Sun), Virgo (Mercury), Libra (Venus), Scorpio (Mars), Sagittarius (Jupiter), Capricorn (Saturn), Aquarius (Saturn), Pisces (Jupiter).

Many modern, psychologically-oriented astrologers believe that Uranus is the ruler or co-ruler of Aquarius instead of Saturn, Neptune is the ruler or co-ruler of Pisces instead of Jupiter, and that Pluto is the ruler or co-ruler of Scorpio instead of Mars (with other modern astrologers claiming that Pluto rules Aries and not Scorpio). Traditional astrology adheres to the rulerships system listed in the paragraph above, and the debate continues between those who consider the newly discovered planets as rulers or co-rulers of certain signs (modern astrologers) and those that do not (traditional astrologers).

Some astrologers do not even use the astrological signs at all (mostly Cosmobiologists and Uranian Astrologers/Hamburg School); therefore they do not take into account planetary rulerships and the essential dignities when interpreting an astrological chart.

A planet is strengthened (dignified) if it falls within the sign that it rules. If a planet is in the sign opposite that which it rules, it is said to be weakened (detriment).

Furthermore, a planet is also strengthened when it is in it's sign of Exaltation. For example, the Moon in Cancer is considered "strong" (well-dignified), while in Taurus the Moon is said to be in it's Exaltation. In traditional horary astrology, Exaltation denotes a level of dignity somewhat exaggerated compared to rulership. Seventeenth century astrologer William Lilly compared rulership (e.g. Moon in Cancer) to a king on his throne, with considerable dignity. Exaltation was considered to give the planet (or what it signified in a horary chart) dignity, with the metaphor of an honoured guest - who is the centre of attention but the extent of their ability to act is limited.

A planet in the opposite sign of it's Exaltation is said to be in it's Fall (e.g. Moon in Scorpio), and thus weakened, perhaps seemingly more so than Detriment.

Examples of planets in their Exaltation: Saturn (Libra), Sun (Aries), Venus (Pisces), Moon (Taurus), Mercury (Virgo - although some disagree), Mars (Capricorn).

In traditional astrology, other levels of Dignity were recognised in addition to Rulership, Exaltation, Detriment and Fall. These are known as Triplicity, Term, Face (or Decan), and together are known as describing a planet's Essential Dignity - it's quality or ability to give of it's true nature. Contemporary English astrology John Frawley's book The Real Astrology has more to say on this matter. In addition to Essential Dignity, the traditional astrologer consider's a planet's Accidental Dignity. This is placement by "house" in the chart under examination. Accidental dignity describes the planet's "ability to act". So we might have, for example, Moon in Cancer (dignified by rulership - able to be a "good" Moon), but if in a Horary chart it was placed in the 12th house, it would have (all things considered) very little scope to express it's good nature. The 12th is a cadent house (as are the 3rd, 6th and 9th) and planets in these houses are considered "weak." On the other hand, Moon in the 1st, 4th, 7th or 10th would be much more able to act, as these are Angular houses.

Planets in Succedent houses of the chart (2nd, 5th, 8th, 11th) are generally considered to be of medium ability to act. As well as Accidental Dignity, there are a range of Accidental Debilities, such as retrogradation, Under the Sun's Beams, Combust, and so forth.


Each sign is associated with one of the classical elements (fire, earth, air, or water) and one of the four modalities (cardinal, fixed, or mutable). It is also associated with an area of concern: personal, social, or universal.

  • Fire signs are associated with intuition, passion, and energy. In combination with the other elements, fire feels that earth will smother it, water will drown it, but air will fan and enliven it.
  • Earth signs are associated with sensation, stability, and practicality. In combination with the other elements, earth feels that air will dry it, fire will parch it, but water will refresh and nourish it.
  • Air signs are associated with thought and communication. In combination with the other elements, air feels that water will obscure it, earth will suffocate it, but fire will inspire and uplift it.
  • Water signs are associated with art and emotion. In combination with the other elements, water feels that fire will make it boil, air will evaporate it, but earth will shape and channel it.
  • Cardinal signs are associated with initiation and creativity.
  • Fixed signs are associated with stability and determination.
  • Mutable signs are associated with resourcefulness and adaptability.


The energies associated with each planet are affected by the sign in which they fall in the following way. (Though due consideration will also be given to other conditions within the astrological chart such as the effect of aspects to other planets, the house in which each planet falls, and the classical element in which the particular sign belongs to)

  • Aries (cardinal, fire, personal): assertively, impulsively, head down.
  • Taurus (fixed, earth, personal): resourcefully, thoroughly, devotedly, indulgently.
  • Gemini (mutable, air, personal): logically, inquisitively, superficially.
  • Cancer (cardinal, water, personal): protectively, sensitively, clingingly.
  • Leo (fixed, fire, social): generously, proudly, theatrically.
  • Virgo (mutable, earth, social): practically, efficiently, critically.
  • Libra (cardinal, air, social): co-operatively, fairly, lazily.
  • Scorpio (fixed, water, social): passionately, sensitively, anxiously.
  • Sagittarius (mutable, fire, universal): freely, straightforwardly, carelessly.
  • Capricorn (cardinal, earth, universal): prudently, cautiously, suspiciously.
  • Aquarius (fixed, air, universal): democratically, unconventionally, detachedly.
  • Pisces (mutable, water, universal): imaginatively, sensitively, distractedly.
