Cancer 10: Naming the Older Systems, and Charubel's Image

The Chaldean and Egyptian labels already attached to this closing degree of Cancer's first decan stand for two specific ancient authors. Vettius Valens, writing in Greek around the year 175, divided each sign into three ten degree faces under a rotating planetary sequence, leaving Venus to rule this decan for the whole of Cancer's first third, and Ptolemy's Tetrabiblos separately preserves the Egyptian bounds table, keeping this degree under Venus's own term as well, closing out the longest single planet stretch anywhere in the sign. 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 a bulbous plant just pushing upward from beneath the soil, beginning to unfold and show its beauties as the viewer watches, a picture of emergence caught at its very first visible moment.

In practice, this degree is mostly used to time events through progressions or synastry. That closing coincidence of decan and term is itself worth noting for anyone reading the technical layer closely, since it does not recur often across the full 360 degrees, and it says nothing about which picture tradition happens to be attached to the point.
