The picture already quoted for this degree is John Thomas's, the Welsh nonconformist minister, 1826 to 1908, who wrote as Charubel once he turned to astrology and clairvoyance. His 1898 catalogue gave nearly every degree of the zodiac its own image, well before the 1925 Balboa Park session between Marc Edmund Jones and the clairvoyant Elsie Wheeler that produced the material generally read today through Dane Rudhyar's 1973 restatement. Charubel's book was a late arrival in a considerably older project.
Vettius Valens, writing in Greek around 175, split each sign into three ten degree faces under a rotating planetary sequence, leaving the Sun to rule this degree's decan, the second of Aries, and Ptolemy's Tetrabiblos separately lists unequal bounds among five planets, giving this degree to Mercury's term, a table of rulers only, with no picture attached. The first complete pictorial set for all 360 degrees survives whole in 1494, in Johannes Angelus's Latin Astrolabium Planum, safely public domain but not translatable into English without the translation acquiring its own separate rights. Charubel achieved independently, in English, what Angelus had done in Latin. In practice, a degree defined this precisely is mostly used to time events through progressions or to flag charts sharing the same close point in synastry.
