Cancer 2nd decan
10° - 20°·Subruled by Scorpio
Second decan of Cancer (10°–20°). Subruled by Scorpio - blends Cancer's water nature with Scorpio's qualities.
Traditional reading
Scorpio subrules the middle decan of Cancer under the modern triplicity scheme, with Pluto as its modern ruler and Mars as the traditional one. Interpreters describe degrees 10 to 20 as water deepened: the Cancer instinct to protect acquires intensity, secrecy and strategic patience. Portraits of the archetype emphasize emotional perception that reads undercurrents others miss, loyalty that binds absolutely once given, and a guarded interior behind the sign's soft exterior. Where the first decan nurtures openly, this band is pictured holding its resources and affections in reserve, releasing them selectively and remembering every breach of trust.
Mercury rules this face in the Chaldean sequence, an intellectual note the triplicity reading lacks. Medieval face imagery for the middle of Cancer, in the compilations that transmitted the Picatrix material, mixes pictures of wealth, cleverness and disquiet, and traditional astrologers reading Mercury here stressed shrewdness in domestic and financial matters. The decan system itself predates these planetary glosses by many centuries, having served Egyptian priests as a stellar clock before Hellenistic practitioners folded the thirty-six segments into horoscopic doctrine as faces.
Cancer archetype
Cancer is the sole domicile of the Moon and exaltation of Jupiter. Cardinal water, traditionally tied to nourishment and the household.

The triplicity decan system assigns each decan a subruler from the sign's element triplicity, in zodiacal order. This is the modern Western convention; classical Hellenistic decan assignments (Chaldean order) differ. See methodology.
