Charubel's image for this degree is one of the stranger pictures in his series: a single serpent, but with many heads, arranged in a circle, fangs bared outward from every point on the ring. There is no single head to identify as dominant, no clear front or back to the creature, only a repeated threat facing outward in every direction at once.
The circular arrangement matters as much as the multiplication of heads. A ring of fangs defends its own center completely, with no blind side and no approach that does not meet a mouth already open. Scorpio's reputation for guardedness, for defending what lies within against any single point of attack, could hardly find a more literal image than this one, protection so total it leaves nothing exposed, at the cost of leaving nothing gentle exposed either.
The phrasing now in general circulation for this degree follows Dane Rudhyar's 1973 restatement in An Astrological Mandala, itself built on the 1925 material gathered by Marc Edmund Jones and Elsie Wheeler; that later, copyrighted wording is not reproduced here. Within the Sun's decan and Mercury's closing term, vitality and sharp perception combine in a creature that has apparently decided the only safe orientation is every orientation, all at once, permanently.
