Mutable

Meaning

Mutable is one of the three modes, or modalities, of the zodiac, with cardinal and fixed. The mutable signs, Gemini, Virgo, Sagittarius and Pisces, close each season, as one turns into the next, and astrologers read them as adaptability: adjusting, learning, connecting, preparing what comes after.

Each element adapts in its own way. Gemini adapts through ideas and words, Virgo through practical adjustment and skill, Sagittarius through exploration and a wider view, Pisces through empathy and letting go. A chart with many planets in mutable signs tends to be flexible, curious and good with change; its gift is responsiveness, the ability to learn and to serve where it is needed. Its difficulty is commitment: attention spread thin, decisions put off, a shape that changes with every setting.

The four mutable signs stand at right angles to one another, two pairs of opposites crossed by squares. Planets spread across them, in a T-square or a grand cross, are often read as a restless, many-sided energy, which steadies once it chooses where to go.

In practice

• A mutable emphasis in the balance of a chart describes ease with changing plans, and some difficulty settling on one.
• A mutable Sun, Moon or Ascendant brings that quality to identity, to needs or to the first impression.
• The cadent houses, the 3rd, 6th, 9th and 12th, which fall away from the angles, are often compared with the mutable signs in modern practice.

Across traditions

• Jyotish calls these signs dvisvabhava, of double nature, the same grouping and the same idea of two natures in one.
• The Chinese calendar reads the end of a mutable sign differently: the solstices and equinoxes that close them mark, for it, the middle of a season, not its end.

Origin and history

Ptolemy called these signs bicorporeal, double-bodied, because they come between the solid signs and those of the solstices and equinoxes, and share, at their end and their beginning, the natures of two seasons. Three of them are drawn as double figures: the Twins, the two Fishes and the Archer, half human and half horse. Latin authors called them common, and Lilly still writes of common signs; mutable, changeable, is the modern English word.

How Ulune calculates it

The chart’s first page counts the ten planets, from the Sun to Pluto, in mutable signs, and the table weighs every body, the Sun, the Moon and the Ascendant most, the outer planets least, leaving the angles out without a birth time.
