The Decans
Aries · First Face
Aries decan 1 · sub-ruled by Mars
The first face of Aries — the ten degrees from 0° to 10°, carrying Mars as their Chaldean sub-ruler.
Mars over Aries is the pure spark of beginning: bold, direct, and quick to move. Its courage is real, and its work is to aim before it fires.
The First Degree of Beginning
The first face of Aries occupies the opening ten degrees of the zodiac, from 0° to 10°, the very threshold where the wheel turns toward spring. In the classical system of decans—those three ten-degree divisions within each sign—this first face answers to Mars, the same planet that rules Aries itself. This doubling of Mars creates an intensity: pure Martian energy, undiluted by the moderating influence of other planets. It is the decan of initiation, of the spark before the flame, of the moment when intention becomes movement.
The tradition of decans reaches back to Egyptian astronomy and was inherited and refined by Hellenistic and medieval astrologers. Each sign's three faces were assigned to different planetary rulers in a sequence that reflects the ancient understanding of celestial influence. For Aries, Mars governs not only the whole sign but returns as lord of its first ten degrees, suggesting that here we meet Aries in its most concentrated form.
Courage Without Hesitation
To encounter this decan is to meet boldness in its most naked form. Mars in its own sign and face knows no self-doubt; it is the warrior before the battle, clear-eyed and ready. Yet this is not recklessness—Mars is a planet of will and directed action, not blind impulse. The first face of Aries speaks to those who must act quickly, who feel the urgency of beginning, who possess the courage to stand alone at the threshold.
This is the decan of pioneers, inventors, and those who break new ground. It governs the first breath, the first word, the declaration that changes everything. It is associated with youth, with the raw power of untested strength, and with the virtue of direct speech. Those born under this face often feel called to lead, to initiate, to be first—and their gift is the ability to move when others are still considering.
The Spark Across Time
In medieval grimoires and astrological texts, this face was linked to the archangel Machidiel and carried associations with vigor, enterprise, and the overcoming of obstacles. Artists and scholars of the Renaissance mapped the decans to virtues and divine names, seeing in them a ladder of perfection. Mars as first ruler represented the virtue of fortitude—not mere aggression, but the strength to begin what must be begun.
In myth, this decan resonates with figures of first action: Ares in his capacity as the god who kindles courage, Prometheus bringing fire, the moment of genesis itself. It is not the Mars of war's aftermath, but of the decision to fight.
Reflection: Where Do You Begin?
If you find yourself born under these degrees, or if this face appears prominent in a moment you are considering, the invitation is inward: What am I being called to start? Where does my true courage lie—not in recklessness, but in the willingness to act before all certainty is won? Mars in Aries' first face asks you to examine the difference between hesitation born of wisdom and hesitation born of fear. It reflects back your own capacity for directness, your ability to name what you see and move toward what calls you. Do you trust your own impulse? Can you distinguish between speed and haste?
