Where Gemini sits in the wheel
Axis partner · 180°
Sagittarius
The sign directly opposite. Every axis has a lesson: the way Gemini’s instinct gets completed — or challenged — by Sagittarius’s.
air triplicity
Gemini · Libra · Aquarius
The three signs that share Gemini’s elemental key. Trines form naturally between them — they move by the same logic even when they look nothing alike.
mutable quadruplicity
Gemini · Virgo · Sagittarius · Pisces
The four signs that share Gemini’s modality — its way of moving through change. Squares and oppositions between them carry the same tension, played in different keys.
Decans — the sign in three acts
Each sign divides into three 10° decans, each with its own Chaldean planetary ruler. A Sun at 4° Gemini lives in the first decan and takes a different colour from a Sun at 24°, even though both are Gemini.
I
0° – 10°
Ruled by Jupiter
II
10° – 20°
Ruled by Mars
III
20° – 30°
Ruled by Sun
