Libra 2nd decan
10° - 20°·Subruled by Aquarius
Second decan of Libra (10°–20°). Subruled by Aquarius - blends Libra's air nature with Aquarius's qualities.
Traditional reading
Between ten and twenty degrees, modern triplicity doctrine hands Libra to Aquarius, the second air sign in zodiacal order, with Uranus as subruler and Saturn as that sign's traditional lord. Commentators describe this middle band as Libran fairness scaled up from the personal to the collective: the concern with balance becomes a concern with principle, the courteous negotiator becomes an advocate for equitable systems, and the aesthetic sense favors clean, idealized, almost geometric forms. The sociability of the sign is said to widen here into friendship networks and causes rather than one-to-one bonds.
The Chaldean sequence gives this decan to Saturn, a ruler that harmonizes neatly with the modern subrulership, since Saturn is also the traditional ruler of Aquarius and holds exaltation in Libra itself. Medieval face lists accordingly paint the second face of Libra in sober colors, and some Renaissance image-texts attach figures of quiet judgment to it. Practitioners who compare the systems often note this decan as a rare point of convergence, where the newer elemental scheme and the older planetary chain point toward the same restrained, principled register within an otherwise gracious sign.

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.
