Cancer 1st decan
0° - 10°·Subruled by Cancer
First decan of Cancer (0°–10°). Subruled by Cancer - the pure expression of the sign's archetype.
Traditional reading
Water doubles back on itself in the first decan of Cancer, which the modern triplicity system assigns to Cancer and the Moon. Astrological writers present this band as cardinal water undiluted: protective instinct that mobilizes quickly, moods that ebb and flow visibly, and attachment to home, family and the familiar past. Common descriptive touches include a memory that archives feelings as much as facts, hospitality as a primary mode of care, and defensiveness that appears the moment anything beloved seems threatened. The initiating side of the sign shows in these portraits as active nurture, gathering and feeding rather than passive sentiment.
The Chaldean faces give the first ten degrees of Cancer to Venus, a gentler assignment that medieval astrologers found congenial; the imagery attached to this face in Picatrix-derived sources involves affection, feasting and the pleasures of family life. In the older Egyptian arrangement the decans were rising star groups that governed the hours, and their absorption into Hellenistic astrology as faces made them the least weighty of the essential dignities, a point traditional authors repeated when cautioning against reading too much into any single decan ruler.

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.
