The image already quoted for this degree is John Thomas's, the Welsh nonconformist minister, 1826 to 1908, who became an astrologer and clairvoyant under the pen name Charubel. His 1898 book, The Degrees of the Zodiac Symbolised, covers nearly all 360 degrees, published decades before Marc Edmund Jones and Elsie Wheeler produced the material now generally read through Dane Rudhyar's 1973 rewrite in 1925. Charubel's picture set was itself a late arrival in a much older habit of subdividing the degrees.
Vettius Valens, writing in Greek around 175, split each sign into three ten degree faces under a rotating planetary rulership, still recorded here as this degree's Mars decan, and Ptolemy's Tetrabiblos separately lists unequal bounds among five planets, giving this degree to Venus's term, a table with no pictures attached to it at all. The first complete pictorial set for every degree survives whole in 1494, in Johannes Angelus's Astrolabium Planum, a Latin work safely in the public domain, though its English translations are not.
Charubel worked independently of Angelus and of the Sabian material that came after him. In practice, a degree defined this narrowly is generally read against a progressed Sun, Moon or angle reaching it exactly, or against a second chart sharing the same point closely enough for synastry, uses that postdate every one of the older systems recorded above.
