Before Jones and Wheeler ever met, the Welsh astrologer Charubel had already published a complete set of 360 degree images in 1898. For this degree, his book pictures a comet (like the one in 1882). It falls in the first decan of Scorpio (degrees 1 to 10), and is Scorpio's eighth degree. Its decan is ruled by Mars, Scorpio's own planet, reinforcing rather than complicating the sign's usual character.
The narrower term division belongs to Venus, a still finer layer of rulership laid across the sign and decan. Behind every one of these 360 degrees sits the same 1925 event: Marc Edmund Jones and the clairvoyant Elsie Wheeler in Balboa Park, San Diego, drawing blank cards in random order and setting down what she saw. Jones's book came out in 1953.
What is usually quoted today, however, is Dane Rudhyar's later reworking, published in 1973 as An Astrological Mandala, a copyrighted text this page does not reproduce. As the middle water sign, Scorpio does not merely feel; it investigates, and it does not let go easily. What a degree reading offers here is orientation rather than forecast, a way of naming exactly where in Scorpio's cycle a person or moment sits. Element and quality carry through every degree of Scorpio: it is a fixed water sign, and this degree inherits that basic temperament even as the decan and term add their own note.
