Quick answer: In classical humoral medicine, each season carried a temperament: spring is sanguine (hot and wet), summer choleric (hot and dry), autumn melancholic (cold and dry), and winter phlegmatic (cold and wet). The season of birth was read as one influence on a person's temperament, working alongside the Ascendant, its ruler, and the Moon.
Long before the birth chart, physicians read the human constitution through the turning year. The four seasons were the clearest image of the four qualities at work in nature, and classical medicine mapped them directly onto the four humors of the body. To be born in a given season was to arrive in a particular balance of heat and cold, moisture and dryness. That balance was thought to leave its mark. This post follows one specific thread, the season of birth, and how it ties to the solar signs that fill each quarter of the year.
The Seasons as the Four Qualities in Nature
Classical physics, following Aristotle and Galen, built the world from two pairs of primary qualities: hot or cold, and wet or dry. The four seasons displayed this scheme plainly. Spring is warm and moist as life returns. Summer is hot and dry at the height of the Sun. Autumn cools and dries as things wither. Winter is cold and wet with rain and snow. The Hippocratic text On the Nature of Man, the founding source of humoral theory, states the correspondence outright, tying each humor to a season and to a stage of the year. The seasons were not a metaphor for the humors. They were the same qualities showing themselves in the heavens and on the earth.
The Four Seasonal Temperaments
From that base, the pairing of season and humor is straightforward, and it lines up with the elements and temperaments a classical reading still weighs. You can explore the fuller framework in temperaments and the four elements. Here the focus is the seasonal quarter itself.
| Season | Qualities | Humor | Temperament | Element | Solar signs | | --- | --- | --- | --- | --- | --- | | Spring | Hot + Wet | Blood | Sanguine | Air | Aries, Taurus, Gemini | | Summer | Hot + Dry | Yellow bile | Choleric | Fire | Cancer, Leo, Virgo | | Autumn | Cold + Dry | Black bile | Melancholic | Earth | Libra, Scorpio, Sagittarius | | Winter | Cold + Wet | Phlegm | Phlegmatic | Water | Capricorn, Aquarius, Pisces |
The signs listed are the tropical signs the Sun passes through in the northern hemisphere from each equinox or solstice. Note that the seasonal element and the elemental triplicity of a sign are two different maps. Spring is a sanguine, airy quarter even though it opens with fiery Aries, because the season is read as a whole rather than sign by sign. The four elements in astrology sort the signs one way; the seasons sort the year another way; and a full reading holds both.
Spring and Summer: The Hot Half of the Year
The spring quarter runs from the vernal equinox through Aries, Taurus, and Gemini. It was called sanguine: hot, moist, growing, and abundant, the temperament of blood and of a warm, sociable, hopeful nature. This is the season of increase, and classical writers linked it to youth and to rising vitality. The summer quarter runs from the solstice through Cancer, Leo, and Virgo. It was choleric: hot and dry, the temperament of yellow bile, quick and burning. Ptolemy discusses the seasons in exactly these terms of heat and moisture in the Tetrabiblos, where he treats the qualities of the year. Galen made the seasonal balance central to his account of health, since a hot season could inflame an already hot constitution.
Autumn and Winter: The Cold Half of the Year
Autumn runs from the autumnal equinox through Libra, Scorpio, and Sagittarius. It was melancholic: cold and dry, the temperament of black bile, the season of harvest, decline, and inward turning. Classical medicine treated autumn as a delicate time, when the drying and cooling of the year could tip a constitution toward heaviness. Winter runs from the solstice through Capricorn, Aquarius, and Pisces. It was phlegmatic: cold and wet, the temperament of phlegm, slow, still, and receptive. Avicenna, whose Canon of Medicine carried Galenic theory into the medieval world, wove these seasonal qualities into his account of how the body's balance shifts across the year. That theme is taken up again in Avicenna and astrological medicine.
Where the Season Fits in a Reading
Here the tradition is careful, and so should we be. The season of birth was never treated as the whole temperament. In a classical assessment, the strongest voices are the Ascendant and its ruler, the Moon by sign and phase, and the sect of the chart. The season is added as one further thread that tilts the overall balance. A summer birth might lean the constitution warmer and a winter birth cooler, but a strong watery Ascendant or a well placed Saturn could easily outweigh the quarter. The autumn or Saturnine side of this scheme is explored further in Saturn and melancholy, which takes up the deeper cultural life of the cold and dry temperament. The point is proportion, not a single stamp from the calendar.
Frequently Asked Questions
Does being born in summer make me choleric?
Not by itself. In classical theory, a summer birth adds a hot and dry, choleric note to the balance. But temperament is weighed mainly from the Ascendant and its ruler, the Moon, and the sect of the chart. The season is one thread among several, and a strong watery or earthy placement can easily outweigh it.
Why does spring map to air and summer to fire when the signs differ?
The seasonal scheme reads each quarter as a whole through its qualities: hot and wet for spring, hot and dry for summer. So spring is sanguine and airy, and summer is choleric and fiery. This is a different map from the elemental triplicity of individual signs, and a full reading uses both rather than forcing them to agree.
Does the season reverse in the southern hemisphere?
The physical seasons do reverse south of the equator, and this is one of the honest tensions in a tradition built in the northern Mediterranean. Most classical texts assume the northern year. A thoughtful modern reading treats the seasonal layer as symbolic and gives more weight to the chart factors that do not depend on latitude.
