Aries 3rd decan
20° - 30°·Subruled by Sagittarius
Third decan of Aries (20°–30°). Subruled by Sagittarius - blends Aries's fire nature with Sagittarius's qualities.
Traditional reading
Sagittarius subrules the final decan of Aries in the modern triplicity arrangement, so Jupiter's expansiveness colors degrees 20 to 30. Writers characterize this band as cardinal fire loosened by mutability: the Aries drive turns outward toward horizons, causes and journeys rather than personal contests. Typical descriptions include enthusiasm that recruits others into a shared mission, restlessness expressed as travel or philosophical searching, and a franker, more good-humored version of the sign's famous bluntness. The combativeness of early Aries is portrayed here as crusading zeal, energy spent on ideas as readily as on rivals.
Under the Chaldean order this decan belongs instead to Venus, a striking divergence from the triplicity scheme. Medieval astrologers listed Venus in her face at the end of Aries and some texts associated the image with pleasure-seeking softening martial fire. The disagreement illustrates why decan rulerships were always counted among the minor dignities: the Egyptian decans were originally timekeeping stars, and the planetary assignments layered onto them varied by tradition, with the Chaldean faces surviving mainly in horary and electional practice.

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.
