One further source stands apart from the Jones and Rudhyar material entirely. Charubel's 1898 degree symbols, compiled well before Balboa Park, give this degree something like a forge beneath the surface of the earth. A number of men are working in an almost nude state, owing to the heat. It proves to be an engine room belonging to a large steamer. Counting from Leo's start, this is the fifth degree, placing it in the sign's first decan. Its decan is ruled by Saturn rather than the Sun, which colors the degree with something Leo does not supply on its own.
The narrower term division belongs to Jupiter, a still finer layer of rulership laid across the sign and decan. The original session behind this degree took place in 1925, when Marc Edmund Jones and the clairvoyant Elsie Wheeler drew all 360 cards blind, in Balboa Park, San Diego, one degree at a time. Jones printed his results in 1953. The phrasing that most sites and books repeat, though, comes from Dane Rudhyar's 1973 rewrite, An Astrological Mandala, which remains under copyright and is not reproduced here. Leo is fixed fire, a sign that wants its warmth to be visible and its identity to be recognized rather than merely felt. The point of tracking a degree this closely is not to predict an event but to place it exactly within Leo's span.
