Aries I
Mars Decan · 0°–10° · Lord of Dominion
"The first face of Aries rises and with it rises a man armed with a coat of mail, holding a sword and a lance; a man of reddish complexion, great courage, and large body."Picatrix — Ghāyat al-Ḥakīm, Book II (c. 1000 CE)
The First Face
The 2 of Wands — Lord of Dominion
In the Golden Dawn system, the pip cards of the Minor Arcana are each assigned to a decan. The 2 of Wands falls in Aries I — Mars ruling the first ten degrees of Aries, the sign Mars itself rules. This is Mars doubled: the planet of will and force operating within the most congenial possible sign, the cardinal fire sign that marks the vernal equinox.
The title Lord of Dominion captures this quality precisely. Dominion is not yet victory (that comes in Aries II, with the Sun's 3 of Wands). It is the moment of seizing command — the first assertion of will over territory, the establishment of authority before the authority has been fully tested. The lord stands on his grounds, surveying what he commands, not yet knowing whether the dominion will hold.
Aleister Crowley, in his Book of Thoth, renders this card as pure Mars in Aries: two crossed fire-wands, blazing. The Waite-Smith tradition shows a figure at a parapet, one wand fixed to the wall, holding a globe — dominion claimed, but still uncertain, the world held in one hand and needing to be won. Both images encode the decan's essential quality: force that has arrived but has not yet consolidated.
The Nature of the First Face
The decan system begins here — 0° Aries, the vernal equinox, the first degree of the zodiacal year. That this first face is governed by Mars is not accidental: in the Chaldean order, which sequences the planets by apparent speed (Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon), the sequence begins with the slowest and most distant planet as the first hour-ruler, but the assignment of decans to signs begins from the sign's own ruler. Aries is Mars's domicile — the sign where Mars rules. So Aries I receives Mars as its decan ruler, and Aries I is where the whole cycle of 36 decans begins.
Mars in Mars's own sign is Mars at its purest and most unmodified. None of the tempering that comes when Mars moves through an alien sign — no Mercury to quicken it into rhetoric, no Venus to soften it into desire, no Saturn to turn it cold and calculating. Here Mars is simply Mars: the principle of force, will, initiative, anger, courage, and the capacity to begin. The fire is cardinal — not the sustained blaze of Leo (fixed fire) or the scattered fire of Sagittarius (mutable fire) — but the first spark, the fire that breaks the winter.
Medieval and Renaissance astrologers regarded Aries I as one of the most potent faces in the entire zodiac — precisely because it concentrates Mars's energy without dilution. Planets in this decan were considered to manifest with exceptional forcefulness, for better or worse. A nativity with many planets in 0°–10° Aries was read as producing individuals of remarkable will, initiative, and combative energy, with corresponding tendencies toward impatience, aggression, and the inability to sustain long projects once the initial fire had spent itself.
Egyptian Origins — The First Star-Keeper
The decan system originates in ancient Egypt, where 36 decan-stars (or star clusters) rose heliacally at 10-day intervals throughout the year. Each decan-star governed a 10-day period, and together the 36 decans divided the solar year into 36 "weeks" of ten days each. The decan rising at the eastern horizon in the hour before dawn was the active decan — the spirit governing that time.
The first decan of the Egyptian system was associated with the star Thuban in Draco (which served as the pole star in the third millennium BCE) and with the god Khnum — the ram-headed creator god who fashioned souls on his potter's wheel. The association of the first decan with the ram was already present in Egypt before the Greek synthesis assigned it to Aries. The Ram was the first sign, and its first face carried the creative generative energy of the beginning.
In the Hellenistic-Egyptian synthesis, each decan acquired not only a planetary ruler but a presiding spirit — what the Picatrix tradition would later develop into elaborate talismanic images. The spirit of the first Aries decan was consistently described as martial and fiery, a warrior-figure whose essence was the capacity to initiate, to strike, and to command.
Picatrix — The Talismanic Image
"The first face of Aries. In it rises a man of dark complexion, blood-red eyes, large body, and angry aspect, girded with a white cloth, armed with a coat of mail and lance. He has great courage. This is a face of courage, dominion, and lordship."Picatrix, Book II, Chapter 11 — trans. John Michael Greer & Christopher Warnock
Mars in His Own Sign — The Undiluted Principle
When a planet rules a decan within its own domicile sign, the effect is a concentration and purification of that planet's essential nature. In traditional astrology, this is called essential dignity — the planet operating from a position of strength, unhindered by the alien nature of the sign it inhabits. Mars in Aries has essential dignity by domicile; Mars in the first decan of Aries has that dignity doubled by the decan rulership as well.
This creates a quality that is not merely strong but archetypal. Aries I is Mars stripped of everything except Mars — the bare principle of initiating force. It is the moment before strategy (that requires Mercury), before purpose (that requires Jupiter), before love (that requires Venus). It is the force that says "I will" before knowing exactly what it wills — the volitional act at its most primary.
In Kabbalistic correspondence, Mars governs Geburah — the fifth sephirah, the sphere of severity, judgment, and the breaking power that makes renewal possible. The first decan of Aries thus carries a Geburahic quality at its most undiluted: the power to cut, to separate, to assert. The warrior who stands in Aries I holds the sword before the battle begins — the sword that might build a kingdom or destroy one.
