♑ Capricorn
cardinal earth · Sun in Capricorn: December 21 – January 20, 2026 (computed from the ephemeris)
Capricorn begins at the winter solstice, the year's darkest and most decisive turn — and the sign carries that economy: maximum structure, minimum waste. Cardinal earth ruled by Saturn initiates the way institutions do, by building something intended to outlast its builder. Mars is exalted here; drive gains discipline, and ambition acquires patience.
The strength is the long game played seriously — competence compounding over years. The shadow is the same seriousness mistaken for the whole of life: usefulness as the only measure, austerity worn as armour. The knees and the skeleton are Capricorn's parts — what bends just enough to climb, and what holds everything up.
In the tradition
| Ruler | Saturn |
| Exalted here | Mars |
| In detriment | Moon (it rules the opposite sign) |
| In fall | Jupiter (exalted opposite) |
| Body-map | the knees and skeleton |
Every fact above is read from the same dignity tables the chart engine uses — the reference cannot drift from the math.
The three decans
| Decan | Chaldean face | Triplicity ruler |
|---|---|---|
| 0°–10° | Jupiter | Saturn |
| 10°–20° | Mars | Venus |
| 20°–30° | Sun | Mercury |
Two systems, honestly both: the Chaldean faces walk the seven classical planets in slowest-to-fastest order continuously through all 36 decans; the triplicity decans hand each third to the ruler of the next sign of the same element.
The axis, and the sign's kin
Capricorn faces Cancer across the wheel; the axis is about home and work: the life that shelters you against the life that measures you.
