Individual degree meaning is a later layer over 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, and this degree stays in Gemini's second decan, ruled by Mars rather than by Mercury, while Ptolemy's Tetrabiblos now moves this degree into Venus's bound, the finer division parting from the decan above it. 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 stairs, or a large step ladder, with a landing and a hand rail at the top that leads to nowhere, a picture of effort spent climbing toward an ending that offers no further destination. 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 progressions or to flag two charts sharing it in synastry.
