Are Scorpio and Pisces compatible?

Scorpio and Pisces are a trine: both water signs, one fixed and one mutable, four signs apart on the zodiac wheel. Astrologers have called the trine the most harmonious angle since Ptolemy. Only the Suns are compared here. Venus, Mars, the Moon and the sign on the descendant carry the rest.

You're here because of someone.

The Sun signs say easy. Two whole charts say far more.

Your card is worked out from the day, the minute and the place you were born, not from a sign you share with a twelfth of the planet.

What it is: synastry, the art of comparing two charts

Comparing two people's charts has a name: synastry. Astrologers lay one chart over the other and look at the angles between the two sets of planets, the same angles the old books use inside a single chart.

Sun-sign compatibility is the shortcut version. It compares only the two Suns, and the angle between them is the aspect: four signs apart is a trine, two apart a sextile, three apart a square, six apart an opposition. Ptolemy called the trine and the sextile harmonious, and the square and the opposition disharmonious. ¹

Elements describe temperament (fire, earth, air, water) and modes describe pace (cardinal starts, fixed holds, mutable adapts). A pair can share one, both or neither. Scorpio and Pisces share the element but not the mode.

Full synastry goes much further: whose Venus lands on whose Moon, where one person's planets fall in the other's houses, how the two descendants line up. Ptolemy himself compared the Sun and the Moon of both charts, not just the Suns. That is why the same Scorpio can get on beautifully with one Pisces and not at all with another. ²

Why do Scorpio and Pisces click?

The traditional portrait: the same for every Scorpio and every Pisces.

Scorpio in love

Scorpio, in the old portrait, loves privately and all the way down. Slow to trust, said to test before it commits, and loyal once it does. The books give Scorpio a long memory, for kindness and for slights, and no patience for anything shallow. For a Scorpio, small talk is a doorway, never the room.

Pisces in love

Pisces loves like a song you can't get out of your head, in the old books: romantic, devoted, and ready to see the best in someone long after the evidence runs out. Traditionally a Pisces gives everything and needs gentleness back. The fish can drift, the story goes, but it always swims toward kindness.

Together

Water with water. Astrologers say these two feel the mood in the car before anyone's said a word. Deep end, both of you. Who remembers to come up for air?

Fixed meets mutable, the rock and the river in the old reading. One holds still and the other flows around it.

The most mysterious trine on the wheel. Scorpio guards the door and Pisces doesn't really believe in doors. Tradition gives them a bond that barely needs words, a lot of late nights, and a shared suspicion of anyone who says it's only a feeling.

Worked out, not guessed

Scorpio is sign 8 of 12 and Pisces is sign 12: four signs apart, 120°. Trines always share the same element and the same polarity, but not the same mode. Of the 78 possible sun-sign pairings, 12 are trines.
Venus never gets more than about 47° from the Sun, so a Scorpio's Venus is in one of five signs (Virgo, Libra, Scorpio, Sagittarius or Capricorn) and a Pisces's in one of five (Capricorn, Aquarius, Pisces, Aries or Taurus). Which one is a matter of the year and the day.

If it’s this deep, why are you afraid of going under?

The Sun can’t answer that. These four can, and your card reads every one of them.

Venus · how you love

How do you love, and how do they want to be loved?

That's Venus. It never strays far from the Sun, so a Scorpio's Venus can only sit in Virgo, Libra, Scorpio, Sagittarius or Capricorn, and a Pisces's Venus can only sit in Capricorn, Aquarius, Pisces, Aries or Taurus. Two people with the same sun sign can want completely different evenings.

Your card reads your Venus.
Mars · what you want

Why does it hurt so much when they drift?

That's Mars: desire, temper, the way you chase what you're after. It can sit in any of the twelve signs, so two Pisces born a season apart can want, and fight about, completely different things.

Your card reads your Mars.
The Moon · what you need

Why do they feel like home one day and a stranger the next?

That's the Moon: what you need when the door's shut and the day's gone wrong. It changes sign every two and a half days. If their Moon falls in your sign… well.

Your card reads your Moon.
The descendant · who you’re drawn to

Why do you keep falling for the same type?

That's your descendant, the edge of the seventh house: the sign setting in the west at your birth minute. Tradition reads it as the partner you keep noticing. It needs your birth time and place.

Your card reads your rising sign and your descendant.
