Where Cancer sits in the wheel
Axis partner · 180°
Capricorn
The sign directly opposite. Every axis has a lesson: the way Cancer’s instinct gets completed — or challenged — by Capricorn’s.
water triplicity
Cancer · Scorpio · Pisces
The three signs that share Cancer’s elemental key. Trines form naturally between them — they move by the same logic even when they look nothing alike.
Decans — the sign in three acts
Each sign divides into three 10° decans, each with its own Chaldean planetary ruler. A Sun at 4° Cancer lives in the first decan and takes a different colour from a Sun at 24°, even though both are Cancer.
I
0° – 10°
Ruled by Venus
II
10° – 20°
Ruled by Mercury
III
20° – 30°
Ruled by Moon

Rulership
At home in Cancer. Strong, native, characteristic — though rulership is not always ease.
Detriment
In Cancer, these planets work harder. What comes naturally at their home sign, comes via friction here.
