Quincunx

Meaning

A quincunx joins two bodies 150° apart, five twelfths of the circle. Their signs are five apart and have nothing in common: not the element, not the modality, not the polarity. Aries and Virgo, Aries and Scorpio, Taurus and Libra. The two functions do not naturally understand each other, and each works by rules the other does not share.

It is read less as a conflict than as a mismatch. Where a square clashes, a quincunx fumbles: two needs that cannot be met at the same time or in the same way, so that one gives way, then the other, again and again. Many astrologers link it with daily routines and habits, where such small corrections are made every day.

Its gift is flexibility. Worked with patiently, a quincunx teaches how to honour two different demands without betraying either, through steady fine-tuning rather than one decisive fix.

Ulune counts the quincunx among the minor aspects, but many astrologers give it more weight than the other minors, and it is the aspect at the heart of the yod.

In practice

• The Sun quincunx the Moon: what one wants and what one needs speak different languages. The answer is usually found in daily rhythm rather than in one big decision.
• Venus quincunx Pluto: lightness and intensity in uneasy contact; relationships that ask to be renegotiated now and then.
• Two quincunxes from one body to the two ends of a sextile make a yod, in which that single body carries the adjustment.

Across traditions

• Indian astrology gives Mars a special glance at the eighth sign from its own, which lies five signs behind it: a quincunx counted by sign.
• The quincunx’s partner is the semi-sextile, at one twelfth of the circle: together they are the two aspects between signs that, for Ptolemy, did not see each other.

Origin and history

In the Tetrabiblos (2nd century), Ptolemy calls signs one or five apart inconjunct: no configuration joins them, so in classical astrology the quincunx was no aspect at all. Johannes Kepler, who proposed new aspects from 1596 onwards, began printing it in his ephemerides from 1621, as the historian David Juste has shown (2010). The name is that of a Roman fraction, the quincunx, five twelfths of a unit, just as 150° is five twelfths of the circle. Its other name, inconjunct, keeps the old word for signs that do not see each other.

How Ulune calculates it

• The quincunx is a minor aspect in Ulune, which keeps the word major for the five Ptolemaic aspects. Its orb is 3°, to an angle as well, and 2° in synastry.
• A quincunx between signs that are not five apart is marked out of sign.
• Though minor, it counts in the configurations: two quincunxes to the ends of a sextile make a yod.
• The Table shows it among the minor aspects. The wheel draws it in the Advanced and All views, or when it is chosen under Bodies, then Aspects.
