       The planets cause illnesses, but the Zodiac signs reveal much about the nature of those illnesses, and the body parts afflicted by them.

Zodiac Man

Zodiac Man. Traditionally, the twelve Zodiac signs are said to represent twelve body parts, from the head down. It's referred to as Zodiac Man, or Astrological Man, and it's a very common motif in illustrations and art of the Middle Ages and the Renaissance. You see several examples of such images on this webpage.

       History is not in total agreement about what body part belongs to what sign, but the pattern is mainly the same — from Aries and the head down to Pisces and the feet. Here is a list of the Zodiac signs and the body parts they are in most traditions said to be connected to:

  • Aries   head

  • Taurus   neck, throat, ears

  • Gemini   lungs, arms, fingers

  • Cancer   chest

  • Leo   heart, blood

  • Virgo   abdomen

  • Libra   hips, kidneys

  • Scorpio   genitals, rectum

  • Sagittarius   thighs

  • Capricorn   knees

  • Aquarius   ankles

  • Pisces   feet

       The Zodiac is very helpful in astrological diagnosis, but the meaning of each sign needs to be modified somewhat. Here is what I suggest:

Aries sign (glyph). Aries governs the head and brain, and their ailments — damages to the skull as well as headaches and brain hemorrhage. Aries is the sign of challenge and impatience, so high tempo and excitement is not unlikely to lead to problems of the head, for example stress leading to migraine and even to brain hemorrhage. On the other hand, people who have Aries strengthened by planets in the sign can take a lot of heat.

Taurus sign (glyph). Taurus governs the throat, neck and ears, also the nose, teeth, and hearing. A strong Taurus gives good hearing and fine teeth, but still an openness to colds and flues. A weakened Taurus often results in getting a cold or a flue, but also hoarseness and problems with the teeth.

Gemini sign (glyph). Gemini governs speech, smell, and the lungs — all things dependent on the flow of air in breathing. Therefore, a strong as well as weakened Gemini tends to attract common colds, whereas a weakened Gemini is also sensitive to flue and cough.

Cancer sign (glyph). Cancer governs the skin, which is the organ for the sense of touch. A weakened Cancer creates skin problems of all kinds. Also a strong Cancer is open to some skin ailments — but it usually results in very healthy skin, sometimes almost radiant.

Leo sign (glyph). Leo governs the heart and the blood. A weakened Leo influences the heart beat and how the blood flows in one's body, which is cause for concern. A strengthened Leo makes the heart sturdy and the blood healthy — up to a point.

Virgo sign (glyph). Virgo governs the food intake and related intestines, for example and especially the stomach. A weakened Virgo leads to eating disorders and stomach ache. Those with a strengthened Virgo can eat just about anything.

Libra sign (glyph). Libra governs the food processing intestines that absorb nutrition, and the excrement. A weakened Libra results in digestion problems, also things like constipation or the opposite. A strong Libra can lead to similar problems, but mostly makes the metabolism like clockwork.

Scorpio sign (glyph). Scorpio governs the genitals and the hormones. A weakened Scorpio can lead to a diminished sex drive, and a strengthened Scorpio to the opposite. Venereal disease is very much related to Scorpio, and so is the urine. The effects on the hormones are usually subtle and difficult to observe.

Sagittarius sign (glyph). Sagittarius governs the eyes and eyesight. A weakened Sagittarius leads to impaired vision, whereas a strengthened Sagittarius is likely to give perfect eyesight, especially at distance.

Capricorn sign (glyph). Capricorn governs the bones of the body. They are strong if Capricorn is, and weak when Capricorn is. Also accidents involving the bones can be spotted in Capricorn. Especially the spine is a Capricorn thing, therefore also one's posture.

Aquarius sign (glyph). Aquarius governs the arms and legs, and one's ability to move about in general. A weakened Aquarius causes impaired movement, for example clumsiness, whereas a strengthened Aquarius gives stamina and elegance to the movements. Also the hands and feet are related to Aquarius, but they tend also to be influenced by some other signs, depending on the situation and ailment.

Pisces sign (glyph). Pisces governs the nervous system, therefore also the reflexes. A weakened Pisces can lead to erratic behavior and some unintentional body spasms, whereas a strengthened Pisces leads to composition and calmness — up to a point. Several but not all ailments of the psyche are related to Pisces.

Far from all the body parts and organs are included in the lists above. For example, there is no mention of the muscles, although they are certainly essential to survival. That's because they can't be connected to one single Zodiac sign. Muscular qualities vary according to their functions and other things — and planets play a role in their development as well as their durability.

       The major but not only planet of muscular power is Mars. If you have Mars in Taurus, you are likely to be quite strong in a sturdy way. If it's in Capricorn your muscles are sufficient and resourceful, if it's in Leo they are evident and impress others, and so on. With Mars in Pisces or Gemini, chances are that you're not that muscular at all.

       Also the sun indicates muscular status, pretty much the same way Mars does.

Power in Zodiac signs

The Zodiac is a background in the horoscope. It doesn't represent actual powers or energies at play. Instead, it gives certain characteristics to them. The working powers in the horoscope are the planets, including the sun and moon, the Ascendant and Medium Coeli. These are the active ingredients in the horoscope.
Zodiac Man. Illustration from late 14th century England.        A Zodiac sign without any of the planets is not really weakened, from a health perspective. Rather, it implies that health issues belonging to that Zodiac sign are no real problems. The empty Zodiac signs in your horoscope show that you rarely have ailments in the body parts those signs govern.

       There are three exceptions: if a Zodiac sign is in the 12th, 6th or 8th House, it can cause some trouble whether it's empty or not. More about that below, when the role of the Houses in your health is discussed.

       As for Zodiac signs that have planets in your horoscope, it generally means they are enhanced. A planet brings energy to the Zodiac sign, so it becomes stronger and more important — also the body part that it governs.

       But there are exceptions to the rule, and several things to consider. A planet in a Zodiac sign can just as well lead to complications. You have to look at the whole picture.

Parts of the Zodiac sign

A Zodiac sign is not exactly the same all through its 30 of the complete Zodiac circle. The beginning of a sign is forceful, whereas the end of it is kind of dissolving, and there are many nuances in between.

       A traditional way of taking this into account is the division of a sign into three parts of 10 each, called decanate or decan. The first decan is cardinal (leading), the middle fixed, and the third is mutable (following). These three qualitites are also divided among the Zodiac signs in whole, so that some are cardinal, others fixed or mutable. There is great order to it: Each of the four Greek elements (fire, air, earth, and water) have three Zodiac signs, and these three are of one quality each. Here are the elements and qualitites of the Zodiac signs:

  Cardinal Fixed Mutable
Fire Aries Leo Sagittarius
Earth Capricorn Taurus Virgo
Air Libra Aquarius Gemini
Water Cancer Scorpio Pisces

Zodiac Man. Ketham,1494.

       Since the decans of a Zodiac sign can also be divided into cardinal, fixed, and mutable, a decan of a Zodiac sign tends to be slightly similar to the sign of that element with the quality of that decan. It also means that a Zodiac sign is the most typical and characteristic in the decan of the quality that sign itself belongs to.

       For example: Aries is the cardinal fire sign, so its first decan, the cardinal one, shows the most distinct Aries characteristics. Its second decan, the fixed one, is slightly similar to the fixed fire sign Leo, and its last and mutable decan has some similarities with the mutable fire sign Sagittarius.

       Therefore, a Zodiac sign is its strongest in the decan of the quality that sign belongs to, which is where it is the most characteristic, and weaker in the other decans. A cardinal sign is at the very weakest, quite frustrated, at its mutable decan, and the other way around. A fixed sign is usually weaker in its mutable decan than in its cardinal decan, but the difference is not that great.

       Here are the Zodiac signs, and what other sign they have similarities to in their decans. A sign is the most characteristic in the decan that is associated with itself.

  1st Decan 2nd Decan 3rd Decan
Aries Aries Leo Sagittarius
Taurus Capricorn Taurus Virgo
Gemini Libra Aquarius Gemini
Cancer Cancer Scorpio Pisces
Leo Aries Leo Sagittarius
Virgo Capricorn Taurus Virgo
Libra Libra Aquarius Gemini
Scorpio Cancer Scorpio Pisces
Sagittarius Aries Leo Sagittarius
Capricorn Capricorn Taurus Virgo
Aquarius Libra Aquarius Gemini
Pisces Cancer Scorpio Pisces

       Regarding your health in your horoscope, you should pay attention to what decan of the Zodiac a planet is in. That tells you much more about the constitution of that planet, what ailments it might cause, and to what extent.

       Each decan of a Zodiac sing tends to narrow down the body part inflicted, or the kind of infliction. It is not that certain or exact, but the table below gives clues to how the decans modify physical ailments and problems of each sign. These are indications, only, Don't take them too literally.

  1st Decan 2nd Decan 3rd Decan
Aries Skull Migraine Concentration
Taurus Nose Throat Ears
Gemini Smell Lungs Speech
Cancer Skin Hair Touch
Leo Heart Blood Circulation
Virgo Appetite Stomach Digestion
Libra Metabolism Bowels Excrement
Scorpio Sexuality Genitals Hormones
Sagittarius Far-sight Eyes Near-sight
Capricorn Spine Bones Joints
Aquarius Arms Legs Movement
Pisces Coordination Nerves Reflexes

       Some Zodiac signs are more prone to cause mental disorders than physical ones. That's even more true about some planets. Still, any mental disorder tends to lead also to some kind of physical malfunction or ailment — and then the above gives a good indication to what.
