Modality: Cardinal, Fixed and Mutable Signs

The fuller picture

Modality is one of the three ways the twelve signs sort, and it's the one that describes behaviour. Element says what a sign is made of; modality says how it acts. Aries, Cancer, Libra and Capricorn are cardinal — the four signs the Sun enters at a solstice or an equinox, so they're where something starts. Taurus, Leo, Scorpio and Aquarius are fixed, the middle of each season, and they hold. Gemini, Virgo, Sagittarius and Pisces are mutable, the end of each season, where one thing is already turning into the next. Each set takes one sign from each element, which is why the two divisions cut across each other instead of repeating each other, and why a set of four is called a quadruplicity. You'll also meet the older English names, and they're worth learning, because most of the rules are actually phrased in them: cardinal signs are moveable, mutable signs are common, and the common signs are also called bi-corporeal or double-bodied. One warning about the word moveable. It does a second, unrelated job in traditional horary, where moveable goods are portable property and belong to the second house, as against immoveable property — land and buildings — which belongs to the fourth. Same word, no connection.

Whatever the question, modality answers the same thing: how the matter behaves once it's in motion. Not what it is, and not whether it's good. The tradition applies the identical triple to the houses as angular, succedent and cadent, and pairs the two schemes off — which is what lets sign and house be crossed on a single grid. Lilly makes the pairing in his own words, in the middle of a rule for finding stolen goods: the lord of the Moon's term "in an Angle, and in a moveable Signe" sends you one way, "in a succedent and fixed Signe" a second, "in a cadent and common Signe" a third. Angles with the moveable signs, succedents with the fixed, cadents with the common. It is worth knowing that a later school pairs them differently, by speed rather than by his printed order — moveable quickest, common second, fixed slowest, ranked against angular, succedent and cadent in that order — so it lands the common signs on the succedents and the fixed on the cadents. Our timing grid ranks the two axes that second way and crosses them rather than pairing them, so nothing in the app turns on which pairing you prefer. Reading a unit of time off that grid is the best-known use and it has its own page. Everything below is what our own one-line definitions leave out, and it's the larger half of the subject.

Modality answers how many, and whether once or again. On a marriage question, all the significators of the marriage in double-bodied signs says the person marries more than once; the significators in fixed signs, connected only by aspect, says once and no more. A question about children splits the same way. Double-bodied signs point to twins or two children, while fixed or moveable signs on the first and fifth cusps with the Sun or Moon among them point to one child at the time of asking — that second reading is credited to Lilly, and between them the two rules partition the three modalities cleanly. Notice the reasoning. The common signs are the ones whose figures are two of a thing, and the doubling is read straight off as a count. There's no measurement in it and no timing.

The fixed signs also settle whether something stays where it is, and this is where the division earns its keep. On whether a report is true, the angles are read as what holds the shape of the whole chart, so angles in cardinal or mutable signs make the truth itself unreliable, and the strongest case for a true report wants the ruler of the first, the Moon or the Moon's dispositor angular or succedent and in a fixed sign. On whether somebody gets out of confinement, a moveable sign rising says very short, a common sign rising says not for long, and a fixed sign rising says a long time — but only when a heavy planet rules that sign and stands in an angle. On a journey, significators that are swift, eastern of the Sun and in moveable signs argue for a good voyage, while the ruler of the ninth, the ruler of the first and the Moon all in fixed signs is read as a block. In a question about a friendship, a square or an opposition between the two parties in fixed signs and in angles is among the worst testimonies, because fixity is what makes a quarrel durable. Read those four together and the rule is the same each time: fixed keeps a state in place, cardinal moves it, common changes it into something else.

So modality carries no polarity of its own, and treating the cardinal signs as the good news is the commonest way to misread it. Fixity is exactly what you want on "will this last" and exactly what you dread on "will this move"; quickness is welcome on a release and unwelcome on a marriage. The same neutrality runs through the descriptive uses — an illness in a fixed sign is chronic rather than severe, and one in a mutable sign is the sort that shifts about and is hard to name.

Two honest notes before you lean on any of it. The sources aren't consistent about how much work modality does on its own. One passage on wealth uses the sign modality by itself, with fixed delaying, common giving a middling stretch and moveable quickest, where the standard grid would cross it with the house. A passage on when a child arrives drops the house half entirely and gives each modality a range of two units. A marriage table makes the planets' own speed the tie-break on the unit instead. And the confinement ladder above is incomplete as printed: a fixed sign rising whose ruler is neither heavy nor angular falls through all three branches and produces no answer at all. That's a gap in the rule rather than a subtlety in it, and it's better to know that than to work round it without noticing.
