Cancer 6: Naming the Older Systems, and Charubel's Image

The Chaldean and Egyptian labels already attached to this degree 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, the first of Cancer throughout, and Ptolemy's Tetrabiblos separately preserves the Egyptian bounds, closing out Mars's term here, one degree before Venus takes over the finer division as well. 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 game birds, specifically identified rather than left as a generic flock, a picture of wild creatures named with some precision rather than treated as interchangeable.

In practice, this degree is mostly used to time events through progressions or to flag two charts sharing it in synastry. Handling a degree this exactly also means being honest about what the method can and cannot show: a shared degree between two charts is a striking coincidence worth noting, not proof of anything, since the ecliptic only has 360 degrees to distribute among however many charts are being compared.
