The image tradition for this degree goes back to 1925, to a session Marc Edmund Jones held with the clairvoyant Elsie Wheeler in Balboa Park, San Diego, drawing all 360 cards blind and at random. Jones's book followed in 1953, though the phrasing most commonly cited now is Dane Rudhyar's, from his 1973 An Astrological Mandala, a text this page leaves unquoted because it is still under copyright. It falls in the first decan of Libra (degrees 1 to 10), and is Libra's ninth degree. Its decan is ruled by Moon rather than Venus, which colors the degree with something Libra does not supply on its own.
The narrower term division belongs to Mercury, a still finer layer of rulership laid across the sign and decan. 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 a man standing on the top of a high mountain; on the one side a perpendicular rock; he is standing near this precipice with a red flag in his hand, which he is waving by way of signalling a promiscuous crowd, who appear to be rushing on horseback at a gall. As a cardinal air sign, Libra initiates through relationship, weighing one position against another before committing. Taken together, the position, the decan, and the old image give this degree a specific character within Libra rather than a generic one.
