Zodiac Signs: The Twelve Archetypes of Astrological Temperament

What Zodiac Signs Do

In a birth chart, planets describe what kind of psychological energy is active. Houses describe where it appears in life. Zodiac signs describe how that energy behaves.

For example, Mars represents action. Mars in Aries acts quickly and directly; Mars in Virgo acts carefully and analytically; Mars in Pisces acts through intuition and emotion.

The Four Elements

The twelve signs are grouped into four elemental temperaments.

Element	Signs	Core Mode
Fire	Aries, Leo, Sagittarius	Inspiration, courage, immediacy
Earth	Taurus, Virgo, Capricorn	Stability, realism, material craft
Air	Gemini, Libra, Aquarius	Ideas, language, social connection
Water	Cancer, Scorpio, Pisces	Emotion, memory, depth

The Three Modalities

Signs are also grouped by modality.

• Cardinal: Aries, Cancer, Libra, Capricorn. Initiates motion.
• Fixed: Taurus, Leo, Scorpio, Aquarius. Stabilizes and intensifies.
• Mutable: Gemini, Virgo, Sagittarius, Pisces. Adapts and translates.

Common Misunderstanding

Your “zodiac sign” in popular conversation usually means your Sun sign. A full chart also includes Moon sign, Rising sign, and every planet’s sign. This is why two people with the same Sun sign can feel very different.
