Aries 2nd decan
10° - 20°·Subruled by Leo
Second decan of Aries (10°–20°). Subruled by Leo - blends Aries's fire nature with Leo's qualities.
Traditional reading
Between 10 and 20 degrees of Aries the modern triplicity method assigns a Leo subrulership, placing the Sun beneath Mars. Commentators describe this middle decan as fire warmed into steadiness: the raw Aries impulse acquires fixity, pride and a taste for audience. The archetype is said to show a more theatrical assertiveness than the first decan, ambition that wants recognition rather than mere victory, and loyalty offered with dramatic generosity. Where the opening band charges at obstacles, this one is pictured holding ground and performing courage as much as exercising it.
The Chaldean sequence also gives this decan to the Sun, another point where the two traditions coincide. In medieval face tables the Sun at the middle degrees of Aries was read as an image of rulership and boldness, and some Renaissance authors linked the face to nobility of bearing. Hellenistic astrologers inherited the decans from Egyptian temple astronomy, where each ten-degree segment had its own guardian figure; the interpretive gloss of pride and command attached to this band came later, through the medieval Latin and Arabic handbooks.

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.
