Why are they so hard to read?

Are Libra and Pisces compatible?

Libra and Pisces are a quincunx: air and water, cardinal and mutable, five signs apart on the zodiac wheel. It is not one of Ptolemy’s five classical aspects; astrologers call it a minor angle. That is the Sun-sign answer, shared by everyone born under these signs. The personal answer sits in Venus, Mars, the Moon and the descendant.

You're here because of someone.

The Sun signs say not quite. 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. Libra and Pisces share neither.

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 Libra can get on beautifully with one Pisces and not at all with another. ²

Why do Libra and Pisces feel so close and so far apart?

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

Libra in love

Libra is the romantic of the old books, in love with love: candlelight, the right song, a partner who matches the room. Traditionally a Libra courts with charm and keeps the peace at almost any cost, and is happiest as one half of a pair. Make a Libra choose between you and fairness, though, and watch it agonise.

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

Air and water. One thinks it through, the other feels it through, and the old books call them hard to translate. Mist on a lake, or weather at sea?

Cardinal meets mutable. One sets the course and the other adjusts it on the way, which is either teamwork or a lot of U-turns.

Libra loves the kind of beauty you can arrange. Pisces loves the kind you can drown in. Nothing in common in the old system, and a lot of soft music on both sides. Tradition calls it romantic and a little lost, like two people sharing an umbrella and walking in different directions.

Worked out, not guessed

Libra is sign 7 of 12 and Pisces is sign 12: five signs apart, 150°. Quincunxs always share nothing the old system counts: element, mode and polarity all differ. Of the 78 possible sun-sign pairings, 12 are quincunxs.
Venus never gets more than about 47° from the Sun, so a Libra's Venus is in one of five signs (Leo, Virgo, Libra, Scorpio or Sagittarius) 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.

Why do they slip away just as you get close?

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 Libra's Venus can only sit in Leo, Virgo, Libra, Scorpio or Sagittarius, 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 nobody want to be the bad guy?

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.
