The second decan of Aquarius is 10° to 20° of the sign, the sign in its fuller, more settled middle register. In the classical face system this stretch is sub-ruled by Mercury, a second planet laid over Aquarius's own ruler, Saturn. A decan never changes the sign, it tones it: here the Aquarius nature carries a Mercury accent, quickening it toward thought, curiosity, and the need to name things and connect them.

The Mercury face of Aquarius
Aquarius is the reformer, air by element and fixed by mode. Its Mercury face adds quickness and the pull to understand, so a Aquarius of the second decan tends to keep the Aquarius temperament while leaning, more than the sign's other two faces do, toward mind: thought and exchange. Think of it as Aquarius read in a Mercury key.
If this decan is yours, where do you recognise the Aquarius in you carried with a Mercury accent, and where gathering more to think about has become a way of not choosing?
