There is an independent image for this degree from 1898, decades before the Sabian set existed. Charubel's book puts it this way: a figure resembling what is called "the true lover's knot.". Counting from Libra's start, this is the eighth degree, placing it in the sign's first decan. 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. 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. Libra opens the second half of the zodiac and turns air's exchange into a question of balance between two parties. What a degree reading offers here is orientation rather than forecast, a way of naming exactly where in Libra's cycle a person or moment sits. Element and quality carry through every degree of Libra: it is a cardinal air sign, and this degree inherits that basic temperament even as the decan and term add their own note.
