Cancer 17

Still in Mercury's decan and Mercury's term, the language of this degree turns biological and abstract at once: potentialities on many levels unfold outward from a single original germ, one small point of origin producing a branching, multiplying structure the way a seed produces a plant far larger and more elaborate than itself.

Unlike most of the 360 degrees, which picture a scene with people or animals in it, this one is closer to a diagram in words, an idea rendered directly rather than staged, and it sits among the handful of Wheeler's 1925 Balboa Park images that read more like a proposition than a picture. The interpretation on this page is Rudhyar's 1973 wording; Jones, who worked in 1953 from his own brief pencil notes and generally favored the more concrete, scenic images over the abstract ones, is on record finding degrees like this one harder to work with than those with a clear tableau in them. There is little obvious shadow in an image of pure unfolding, though potential that only ever unfolds and never resolves into a finished form carries its own quiet frustration. Cancer, the cardinal sign that starts the year's second quarter, is a fitting home for a degree about origins and germination, the sign's own governing idea, life beginning, given here in its most abstract possible form.

The decan and term already recorded for this degree trace to two named ancient writers. Vettius Valens, writing in Greek around the year 175, divided each sign into three ten degree faces under a rotating planetary sequence, leaving Mercury to rule this decan, the second of Cancer, and Ptolemy's Tetrabiblos separately preserves the Egyptian bounds table, keeping this degree under Jupiter's term as well, the two ancient divisions agreeing here. Neither writer pictured anything, only ruled it. The first complete pictorial set for all 360 degrees survives whole in 1494, in Johannes Angelus's Latin Astrolabium Planum, safely public domain but never freely translated into English.

The next complete English set is Welsh minister John Thomas's, writing as Charubel in 1898, whose entry for this degree describes an artificial globe, a made object standing in for the whole earth rather than the earth itself, a picture of representation substituting for the real thing. Practically, this degree is mostly used to time events through progressions or to flag two charts sharing it closely enough to matter in synastry, both applications considerably younger than the systems named above. None of this technical layering depends on which picture tradition a reader consults, since the decan and term rulers were fixed centuries before either Charubel's book or the Sabian material gave this point in the zodiac a scene of its own.
