Retrograde

Definition

Retrograde describes a planet that appears from Earth to be moving backwards through the zodiac. Nothing reverses in space; the reversal is a perspective effect of two bodies travelling at different speeds on different orbits. Traditional astrology counted it among a planet's debilities. Modern astrology reads it as that planet's business turned inward.

Primary source

When any planet is decreasing in longitude. It is a very great debility.

Deep Understanding

The motion is real as an appearance and unreal as a fact, which is an unusually honest piece of astrological language. Earth overtakes the slower outer planets on the inside of the track, and for a stretch of weeks the overtaken body seems to slide backwards against the fixed stars. Then it halts, which astrologers call a station, and resumes.

The arithmetic matters more than the symbolism here. The same 1852 book gives Saturn one hundred and forty days of retrograde motion, with five days standing still at each station before the direction changes. That is well over a third of every year spent going the wrong way. It is the reason a single exact transit can be met three times rather than once: forwards onto the degree, backwards over it, forwards across it again, all inside the same twelve-month stretch.

Lilly's tradition called it a debility and meant it: a retrograde significator weakened the matter and often spoiled it. The twentieth century inverted the reading without inverting the mechanics. On the modern account the planet is not weaker, it is redirected, and what it governs has to be settled internally before it can work outwardly. Both readings are interpretations laid over the same parallax. Neither is a measurement, and the site has no way to adjudicate between them.

What no reading disputes is the timing problem it creates. A fixed orb is a fixed number of degrees, and degrees stop corresponding to months the moment the planet turns around.

Often confused with

Orb: the degrees of tolerance around an aspect, where retrogradation changes how long those degrees take to cross. Transits: the contacts themselves, which a retrograde loop can multiply. Planetary aspects: the angles, which retrogradation repeats rather than alters.

In Practice

Tonight, find the station rather than the symbolism. Think of one thing you were pushing forward this year that stopped and then started moving the other way: a plan, a conversation, a piece of work. Write down what you did at the halt. Most people force. The teaching inside the word is that the halt is part of the passage, not an interruption of it, and that the same ground gets crossed again. You will know which kind you are by what you wrote.

In Pleroma's Words

It never went backwards. You did, relative to it, and then you called the view a verdict.
