Individual degree meaning sits on top of a much older, planet only system. Vettius Valens, writing in Greek around the year 175, divided each sign into three ten degree faces under a rotating planetary sequence, the scheme behind Venus's rule over this degree's decan, Taurus's own planet, and Ptolemy's Tetrabiblos separately records a table of unequal bounds among five planets, the source of the Venus term recorded here too, the two ancient systems in agreement at this point. Neither writer pictured a degree, only ruled it. A complete run of individual degree pictures first survives whole in 1494, in Johannes Angelus's Astrolabium Planum, a Latin work safely public domain, though its old English translations are not.
The next complete English set is Welsh minister John Thomas's, writing as Charubel, whose 1898 book gives this degree a ram standing alone, looking toward a flock of sheep in the distance, a picture of separation from the group rather than membership in it. Marc Edmund Jones and the clairvoyant Elsie Wheeler produced a separate image for this same degree in 1925, now generally read through Dane Rudhyar's 1973 restatement. In practice, this degree is mostly used to time events through a progressed Sun, Moon or angle reaching it exactly, or to flag two charts sharing it closely enough to matter in synastry.
