Elements and modalities: two ways of cutting the twelve signs
Published 19/07/2026 · 2 min read
Most people know their element. Fewer know the second division — and it is the one that explains why certain pairs keep catching on each other.

The twelve signs are divided two ways at once, and compatibility only makes sense once you hold both.
Four elements
Fire, Earth, Air and Water — three signs each, 120 degrees apart on the wheel. Three signs of one element form a trine, which is why same-element pairs tend to understand each other without effort.
Three modalities
- Cardinal: Aries, Cancer, Libra, Capricorn — the signs that open a season, good at initiating.
- Fixed: Taurus, Leo, Scorpio, Aquarius — mid-season, durable and stubborn.
- Mutable: Gemini, Virgo, Sagittarius, Pisces — closing a season, adaptable and easily scattered.
In 2011, the world briefly thought its signs had changed
In January 2011 an astronomer in Minnesota told a local paper something everyone in his field already knew: because of precession, the constellations have drifted from the positions the astrological calendar assigns them, and the Sun also passes through a thirteenth, Ophiuchus.
Within days the story had gone around the world. People panicked, believing their sign had changed. Some talked about removing tattoos.
Nobody's sign changed, because the claim compared two different systems. Western astrology uses the tropical zodiac, anchored to the equinox — it divides the year by season, not by constellation. That the constellations have drifted is something astrologers have known for centuries and have never hidden.
The episode is worth remembering because most arguments about astrology are two sides discussing different things. To argue against astrology you have to aim at what it actually claims — that positions at birth relate to character — and there, controlled studies genuinely find nothing.
Why the square rubs
Two signs 90 degrees apart always share a modality and differ in element. They approach life at the same tempo — both like to initiate, or both dig in — but for unrelated reasons. That is the recipe for constant friction. It is also why many long partnerships sit at this angle: they keep forcing each other to grow.
