Like the other 359 degrees in this set, this one goes back to 1925 and a session in Balboa Park, San Diego, where Marc Edmund Jones drew blank cards at random while the clairvoyant Elsie Wheeler described what she perceived. Jones's book reached print in 1953. The phrasing most people know, though, is Dane Rudhyar's 1973 version, An Astrological Mandala, still protected by copyright and not reproduced on this page. It falls in the third decan of Leo (degrees 21 to 30), and is Leo's twenty seventh degree. Its decan is ruled by Mars rather than the Sun, which colors the degree with something Leo does not supply on its own.
The term ruler here is also Mars, so the finer division agrees with the decan rather than adding a separate voice. This degree also carries an image from a different and earlier tradition. Charubel, writing in 1898, described a large stone falling on the head of a man. As the middle fire sign, Leo turns the raw start of Aries into something performed, sustained, and given a name. Taken together, the position, the decan, and the old image give this degree a specific character within Leo rather than a generic one. Element and quality carry through every degree of Leo: it is a fixed fire sign, and this degree inherits that basic temperament even as the decan and term add their own note.
