Lilith Deep — four variants of the Black Moon
Black Moon Lilith is not a body but a geometric point — the empty focus of the Moon’s elliptical orbit. Astronomers describe it four different ways, and each reads as a different shade of the same wild interior. This tool computes all four with Swiss Ephemeris, places them in your chart, and writes them as state.
Four geometries, one orbit
Mean Lilith is the time-averaged apogee of the lunar orbit — smooth, stable, the most common position in classical Western use. Osculating Lilith is the instantaneous true apogee at the moment of birth, jittery and exact. Interpolated Apogee softens the noise; Interpolated Perigee marks the opposite point, where the Moon comes nearest the Earth. Each is computed via swe_calc_ut with the appropriate flag.
State, not warning
Lilith is often translated as “the demonic feminine” or “the cursed witch”. We refuse that frame. Lilith is the part of you that will not be domesticated — the appetite, the rage, the refusal that keeps you intact. Mean Lilith reads as the long-form theme. Osculating reads as the live charge. Apogee shows where you exile yourself, Perigee where you collapse back. Comparison is the point.
How to read the four together
When Mean and Osculating fall in the same sign, the wild voice is consistent — what you carry quietly is also what flares. When they disagree, you live a split: a long appetite under one mask and an acute one under another. The Apogee–Perigee axis frames the swing: how far you push the refusal away, and how close it returns. Aspects to natal planets are listed for each variant separately.
Where Lilith Deep sits in the wider chart
Read this tool alongside your natal chart, your Chiron placement, and the Pluto/Mars houses. Lilith adds the appetite that other points only hint at. The pairing with /chiron-lilith gives the wound and the shadow desire as a single reading; the natal chart gives the structure inside which both move.
Frequently Asked Questions
Which Lilith should I trust?
None alone. Mean is the canonical Western reference and the easiest to compare with old textbooks. Osculating is the precise instantaneous point. Treat the four as four angles on the same interior — agreement deepens a theme, disagreement reveals a split.
Is Lilith a malefic point?
No. Classical sources read her sharply, but the modern reading on this site frames Lilith as the part that protects integrity by refusing. She is uncomfortable when ignored, freeing when listened to. The text is state-language, not warning-language.
Why include the Perigee?
Apogee shows where the refusal pushes outward; Perigee shows where it pulls back. Without the second point, the reading is half-described. Together they map a swing — the actual rhythm of the appetite over time.
