When the Moon Moves

Contact, Separation, and the Space Between

TL;DR

In ancient astrology, the Moon’s movement toward or away from other planets was considered deeply meaningful. These movements, called contacts and separations, marked beginnings and endings, signals of what was about to unfold or what had already passed. But not every movement carried weight—some were powerful, others fell into silence. This article explores how Hellenistic astrologers understood these lunar transitions and what it means when the Moon is said to be “running in the void.”

There’s a quiet rhythm to the Moon’s motion—an unending path across the sky that we so often forget to notice. Yet to ancient astrologers, every step she took mattered. They watched her not only for eclipses or full light, but for the subtle choreography of how she met, departed from, or passed over the other wandering stars.

In Hellenistic astrology, these transitions were called contacts and separations, and they weren’t just astronomical—they were symbolic thresholds. A moment when something enters our lives. A moment when something leaves.

These teachings come from ancient texts, recently translated and explained in depth by Dr. Levente László of the HOROI Project, an academic endeavor dedicated to recovering and preserving the technical heart of Hellenistic astrology.

The Moon as Intermediary

The Moon moves quickly—faster than any other planet—and because of that, ancient astrologers saw her as a messenger or intermediary. She carries influence from one planet to another, weaving together the meanings of the heavens.

As she travels through the zodiac:

• She contacts a planet when she’s moving toward it.

• She separates from a planet when she’s moving away.

These contacts and separations aren’t just physical proximity—they’re measured by zodiacal degrees, and more importantly, by the astrological bounds—subdivisions within each sign that were thought to carry specific planetary rulership.
