Cancer 30: Naming the Older Systems, and Charubel's Image

The decan and term already recorded for this final degree of Cancer 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 the Moon, Cancer's own planet, to rule this closing decan, and Ptolemy's Tetrabiblos separately preserves the Egyptian bounds table, closing the sign under Saturn's term as well, the two ancient divisions agreeing at this final point. 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 closing degree of Cancer describes an acute triangle with a cross on top of it, a compact geometric figure closing out the sign much as it opened, without a human figure in the scene. Practically, this degree is mostly used to time events through progressions or synastry. None of this technical layering depends on which picture tradition a reader consults, and closing the sign this way is a reminder that the decan and term rulers were fixed centuries before either Charubel's book or the Sabian material gave any of these 360 points a scene of its own.
