Before there was "a chart with a lot of fire", there was "a choleric person". The doctrine of the four temperaments is the oldest way of reading the elements, and for nearly two thousand years it was not one reading among others: it was THE reading, and it counted for medicine as much as for astrology.
This page explains what it says and where it came from. And it states, in plain words, what this site does cannot compute — because the temperament calculation is not the element calculation, and confusing the two is the commonest mistake in the subject.
The four humours, and what ties each to an element
Each element is a pairing of qualities, and each humour is the same pairing. That is the seam between the two systems, and it is no analogy: it is the same definition written twice. Hot or cold, dry or moist — four combinations, four elements, four humours.
| Element | Qualities | Humour | What tradition read in it |
|---|---|---|---|
| Fire | hot and dry | choleric | reacts fast and hard, decides before checking, wears itself out on its own hurry |
| Earth | cold and dry | melancholic | slow to react and slow to let go, checks everything, carries what is already past |
| Air | hot and moist | sanguine | reacts fast and lets go fast, likes people and new subjects, scatters |
| Water | cold and moist | phlegmatic | slow to react and then gives way, accommodates the other person, struggles to say what it wants |
Notice what the two middle columns do together. Hot and cold are the SPEED of the reaction; dry and moist are how long it LASTS. Choleric and sanguine react quickly, and the difference between them is that one holds on and the other lets go. Melancholic and phlegmatic take their time, and the difference is the same. The whole doctrine fits into those two questions.
Where it came from, and why that matters for reading it carefully
The four humours began in medicine, and not in astrology. They are Hippocrates', from the fifth century before Christ, and they arrived organised by Galen five hundred years later: blood, yellow bile, black bile and phlegm were fluids of the body, and their mixture explained illness. Astrology came afterwards, with Ptolemy, offering a way to find out someone's mixture from the sky of their birth.
That order explains the strength of the idea and it explains the danger in it. The strength: the vocabulary is old, tested and concrete — it speaks of speed and of duration, which anyone recognises in themselves. The danger: for nearly two thousand years people were bled because their temperament "called for it". The doctrine survived as a description of temperament, and died as medicine. That is how it holds up, and it is the only way to use it without dishonesty.
What this site computes, and what it does not
This site counts elements and modalities. It does not compute temperament. The grid that appears in the free chart and in the paid reading adds up the ten planets plus the Ascendant — eleven points, all with the same weight — and shows how many fell in each element. That calculation is explained in Elements and modalities, with the distribution measured.
The temperament calculation is a different one, and it has more than one recipe. Tradition weighs the sign of the Ascendant, the planet that rules that sign, the phase and sign of the Moon and the season of the year — and Ptolemy, Bonatti and William Lilly do not combine those ingredients the same way. Two traditional astrologers can arrive at different humours for the same chart, each with a source in hand.
That is why there is no temperament number on this site. Publishing one would mean picking a recipe and not saying which — and a house that shows the ephemeris every degree comes from is not going to hide where a result came from.
Counting the eleven and weighing the three do not give the same answer
Which leaves the practical question, for anyone who has seen their own grid: is the fullest element in the grid my temperament? How well that substitution works can be measured, and it is what this page has of its own.
Tradition does not count eleven equal points: it weighs the Sun, the Moon and the Ascendant above everything else. So I measured the two calculations side by side in 80,004 charts — from 1940 to 2025, in ten Brazilian cities, four times of day per date, with the same ephemeris that builds a chart here:
| What the measurement asked | In how many charts |
|---|---|
| The Sun, the Moon and the Ascendant hold a majority in one element | 62.4% |
| They sit in three different elements, with no majority at all | 37.6% |
| When there is a majority: it is the same as the fullest element in the grid | 72.3% |
| When there is a majority: it points to a DIFFERENT element | 27.7% |
The calculation was redone on a second sample, with another mesh of dates and other times of day, and the 27.7% held.
In more than a quarter of the charts with a majority, the two calculations point to different elements. Anyone taking the fullest element in the grid for their temperament is right in about three cases out of four — and does not know which of the four they are in.
And the bottom number is the more interesting of the two: in 37.6% of charts the Sun, the Moon and the Ascendant sit in three different elements, and the trio points to nothing. More than a third of people have no dominant temperament by the very calculation tradition weighs most — which tradition settled with a tie-breaking rule, and modern astrology settles by describing the three points one by one.
Why tradition weighed those three in particular
Because the three are the body, and not the subject matter. The Ascendant is the horizon of the instant of birth: it changes sign every two hours, and it is the most individual piece of the chart. The Moon is the immediate reaction, the one that shows up before any decision. The Sun is what organises the rest. An astrologer who wanted to classify someone's nature looked at what was most that person and least their generation.
It is the same reason Uranus, Neptune and Pluto weigh little in a personality reading: they stay years in the same sign, and describe a whole cohort. The eleven-point grid counts them with the same weight as the Ascendant — which is honest as counting, and is exactly what makes the two answers part company in that quarter of charts.
What to do with this in practice
The doctrine does not need a calculation in order to be useful. What it offers is a better question than "what is my element", and it has two parts:
Do you react quickly or slowly? And, once you have reacted, do you hold on or let go? Quick and holds on is choleric; quick and lets go is sanguine; slow and holds on is melancholic; slow and gives way is phlegmatic. Anyone who answers both honestly gets closer than any table would — and can then compare that with what the chart shows, which is the use that counts.
And it is worth saying what the comparison will find most of the time: the Sun, the Moon and the Ascendant in different elements, each pulling one way. That is no fault of the chart or of the doctrine. It is what 37.6% of people have.
What temperament does not say about you
Nothing about your health, and this is not a formality. The four humours were medical theory for two thousand years, and the damage they did is a matter of record. Astrology does not diagnose, does not treat and is no substitute for a doctor — and in a subject born inside ancient medicine that line needs saying louder, and not softer.
And the usual limit: astrology does not predict facts, does not diagnose anyone and does not decide for anyone. These are tendencies, and a tendency is something you work with.
Frequently asked questions about the four temperaments
What is my temperament according to my chart?
This site does not answer that, and it is honest to say why: it counts elements and modalities, and the temperament calculation is a different one. Tradition weighs the sign of the Ascendant, its ruler, the phase and sign of the Moon and the season of the year — and the recipes of Ptolemy, of Bonatti and of Lilly do not give the same result for the same chart. Publishing a number here would mean picking one of them and not saying which.
Which temperament matches each element?
Fire is the choleric one (hot and dry), Earth the melancholic (cold and dry), Air the sanguine (hot and moist) and Water the phlegmatic (cold and moist). The two qualities are what ties the systems together: each element is a pairing of hot-or-cold with dry-or-moist, and each humour is the same pairing.
Does counting the elements in a chart give the temperament?
It gives something else, and sometimes a different answer. This site's grid counts eleven points with equal weight; tradition weighs the Sun, the Moon and the Ascendant above the rest. Measured in 80,004 charts: when those three hold a majority element, it disagrees with the fullest element in the grid 27.7% of the time. And in 37.6% of charts the three sit in three different elements, with no majority at all.
Does temperament say anything about my health?
No, and this is the part where the history of the idea asks for care instead of charm. The four humours were MEDICAL theory for two thousand years, and bleedings and purges were prescribed on the strength of them. Astrology does not diagnose, does not treat and is no substitute for a doctor. What survives as useful in the doctrine is a vocabulary of temperament, and not of the body.
Why does modern astrology barely mention temperament?
Because the twentieth century changed the question. Traditional astrology wanted to sort a person into one of four natures in order to decide what to do with them — in medicine included. The modern kind describes pieces of the chart one by one, and the element grid took the place temperament used to hold. That is why almost every program shows the grid and almost none computes the humour.
Questions for people just starting out
The four temperaments in summary
- Choleric Fire, hot and dry — reacts fast and holds on
- Sanguine Air, hot and moist — reacts fast and lets go
- Melancholic Earth, cold and dry — takes its time and holds on
- Phlegmatic Water, cold and moist — takes its time and gives way
- The grid is not the humour the two calculations disagree in 27.7% of charts
- And in 37.6% the Sun, the Moon and the Ascendant hold no majority at all
Hot and cold are the speed of the reaction; dry and moist are how long it lasts. The whole doctrine fits into those two questions — and your chart shows which element the Sun, the Moon and the Ascendant are in, the three that tradition weighs most. See your chart free here.
