Fire, earth, air and water are probably the oldest and most widely shared symbolic language in the West. Before becoming an astrological key, the four elements were a theory of nature: everything that exists, it was thought, arises from their mixture in different proportions. Astrology inherited this vision and transferred it to the zodiac, distributing the twelve signs into four groups of three, the triplicities.
From Empedocles to Aristotle
The Sicilian philosopher Empedocles, in the fifth century BC, spoke of four eternal "roots", mixed and separated by two forces, Love and Strife. Aristotle took up the doctrine and grounded it on two pairs of opposite qualities: hot and cold, the active qualities, and dry and moist, the passive ones. Each element arises from the union of two qualities:
| Element | Qualities | Symbolic movement |
|---|---|---|
| Fire | Hot and dry | Rises, separates, illuminates |
| Air | Hot and moist | Expands, connects, circulates |
| Water | Cold and moist | Descends, unites, envelops |
| Earth | Cold and dry | Concentrates, gives form, supports |
This structure also explains how one element can turn into another: it is enough for one of its two qualities to change. Heated water becomes air (vapour); earth that is heated and dried draws close to fire. It is a dynamic vision, not a static one.
The elements in the zodiac
Each element governs three signs, placed 120° from one another, that is, in trine:
- Fire: Aries, Leo, Sagittarius.
- Earth: Taurus, Virgo, Capricorn.
- Air: Gemini, Libra, Aquarius.
- Water: Cancer, Scorpio, Pisces.
The sequence of signs alternates the elements regularly in the order fire, earth, air, water. As a result, signs of the same element always stand in geometric harmony, which is one of the reasons tradition regards the trine as a favourable aspect.
The triplicity lords
Hellenistic and medieval astrology assigned "lords" to each triplicity, different according to whether the birth or event took place by day or by night. In the most widespread system, for instance, the fire triplicity is ruled by the Sun by day and Jupiter by night, with Saturn as participating lord. It is one of the five essential dignities of the planets, used to assess their strength.
Elements and temperaments
Ancient medicine, from Hippocrates to Galen, linked the elements to the four humours and the temperaments. This doctrine, long superseded as medical science, remains a symbolic heritage of great interest:
- Fire and yellow bile: the choleric temperament, energetic, quick to act.
- Air and blood: the sanguine temperament, sociable, optimistic.
- Water and phlegm: the phlegmatic temperament, calm, receptive.
- Earth and black bile: the melancholic temperament, reflective, deep.
The seasons followed the same scheme: warm and moist spring was sanguine, hot and dry summer choleric, cold and dry autumn melancholic, cold and moist winter phlegmatic.
The balance of elements in the birth chart
A simple way to approach a birth chart is to count how many planets fall in each element. You can use the seven traditional planets plus the ascendant, perhaps giving greater weight to the Sun, the Moon and the ascendant.
- A chart with much fire suggests drive and initiative, with the risk of impatience.
- With much earth, practicality and perseverance, with the risk of rigidity.
- With much air, thought and communication, with the risk of scattering.
- With much water, sensitivity and empathy, with the risk of being overwhelmed.
A missing element is not a lack to be feared, but an indication of what to cultivate consciously. At Studio Esoterico Cornelio this reading is used as a first step in self-knowledge, always integrated with the rest of the chart.
The elements as practice
The elements also lend themselves to simple contemplative practices. Many traditions suggest dedicating a meditation to each: gazing at a flame for fire, walking barefoot on the earth, breathing consciously for air, sitting by running water. The point is not to obtain an effect but to recognise in yourself the same qualities you observe in nature.
In short
- The four elements arose in Greek philosophy as a theory of how the world is composed.
- Each element combines two qualities among hot, cold, dry and moist.
- In the zodiac each element governs three signs set in trine to one another.
- Tradition linked the elements to the temperaments and the seasons.
- Counting the elements in a birth chart is a first symbolic tool for self-knowledge.
