Aries and Gemini compatibility
- Elements
- Fire + air
- Modalities
- Cardinal + mutable
- Angle
- 60° sextile
- Rulers
- Mars + Mercury
Gemini is the second sign after Aries. The angle between them is 60°, a sextile, and the pair scores 69 out of one hundred by our formula. The sextile brings most of the angle’s share. Fire and air have one quality in common, which is worth three quarters of the element share. Adaptability is high, because Gemini is a mutable sign. Against that, the rulers, Mars and Mercury, earn no extra points, and steadiness is low. The method is described in how we score.
Alan Leo has a sentence on Gemini with the fiery signs and Ptolemy one on the sextile, and the last section gathers them.
Love & romance
72Love and romance scores 72, and the sextile does most of the work, since the angle is the heaviest input in this facet.
Ptolemy names the sextile next to the trine as harmonious, “being formed between either all feminine or all masculine signs”. That holds here. Aries is among his signs “considered to be masculine and diurnal”, and his third triplicity is “composed of Gemini, Libra, and Aquarius, masculine signs”.
The rulers stay at half their share. Ptolemy in fact separates Mars from Gemini’s group: the airy triplicity goes to Saturn and Mercury, “and not to Mars, to which planet it bears no relation”.
Alan Leo’s portraits, read together by us, share one taste. Aries people are “fond of constant change, loving novelty, romance and speculation”, and of Gemini people he says: “They love change and diversity”.
Trust
58Trust is the lowest facet, 58. Steadiness is a large part of it, and this pair has little: a cardinal sign counts for half, a mutable sign for nothing.
Ptolemy’s name for the mutable signs is bicorporeal. They lie between a fixed and a tropical sign and “participate in the constitutional properties of both”. Lilly calls Gemini a “common or double-bodied” sign, in a line meant for reading charts, not people. Treating doubleness as a lack of steadiness is the formula’s step and ours.
Alan Leo touches the same point and defends it. Gemini people “must have diversity; this may make them appear to their friends very fickle and indecisive, but it is their particular way of working”. Both of his harsher remarks are conditional. Gemini people “become very diffusive, indecisive and unreliable” only “when they live the unbalanced personal life”, and of Aries he writes, “Their greatest fault when perverting their gifts is deception”.
Communication
76Communication is this pair’s highest facet, at 76. Three inputs agree: adaptability, the sextile, and elements that count for three quarters.
Alan Leo credits both signs with quickness in talk, though in separate chapters, so pairing the remarks is our doing. Aries people “make excellent conversationalists” and are “affable, genial and witty”. Gemini people “are certainly quick-witted and mentally impulsive”. He also says they “can very quickly adapt themselves to surroundings or environment”, which we read as the quality the formula calls adaptability.
Emotions
72Emotions comes to 72. Elements weigh most in this facet, and fire and air match in part. Lilly’s lines of qualities show the part: Aries is “hot and dry, cholericke”, Gemini “hot, moyst, sanguine”. Heat is shared; the temperaments have different names.
Alan Leo’s Gemini is a mixed character. “They can present a bold front and assertive attitude, and yet be timid and highly nervous”, he writes, and they “are very sensitive and have the ability to reason upon and analyse their sensations”. His Aries is plainer: “inclined to be very headstrong and impulsive”. Our reading of the two portraits is one sign that acts on a feeling and one that examines it.
Values
60Values scores 60, a little above trust and held down by the same low steadiness.
On what the two care about, Alan Leo gives Aries a single direction and Gemini two. “This sign gives extreme ideality”, he says of Aries. Of Gemini people: “They are conservative and progressive, and altogether quite dualistic subjects, which makes them difficult for others to understand.” The contrast between a sign of one ideal and a sign of two minds is ours.
Shared activities
74Shared activities scores 74, second only to communication. Adaptability counts here too, with the sextile and the partly matched elements.
Alan Leo’s sentences suggest full days on both sides, though the comparison is ours. Gemini people “are rarely content with a single occupation or pursuit, and seem to delight in having two things in hand at the same time”. Aries people, as hosts, “can always be relied upon to provide plenty of entertainment”.
What the old writers say about fire, air and the sextile
Alan Leo’s Gemini chapter has one sentence on marriage: “These persons would do well to marry those born in the airy or fiery triplicities.” Lilly lists Aries as “of the Fiery Triplicity”. Alan Leo names the triplicity, not the sign.
Ptolemy’s chapter on marriage speaks of the Sun and Moon in two birth charts. When they are “either in trine or in sextile to each other, the cohabitation will most usually be lasting”. That is a rule for two full charts; the sextile is the angle these two signs make.
Both are views about signs and angles from earlier centuries, quoted as history, not advice about a relationship.
The score describes two signs. Two people also have Moons, Venus and Mars placements and much else that no pair of signs can show.
