The thirty-six decans

Every sign spans thirty degrees, and each divides into three decans of ten degrees, or faces. A decan never changes the sign, it tones it: a second classical planet, in the Chaldean order, laid over the sign's own ruler to colour that stretch of it. Here are all thirty-six, read as a lens for reflection, never a verdict.
