## What is Mansions of the Moon?

The Moon passes through 28 mansions as it circles the ecliptic — each governed by an angel, each carrying distinct magical influences. This system of celestial magic is older than the tropical zodiac itself, transmitted from Arabic astrologers through Agrippa's Three Books of Occult Philosophy to Barrett's Magus, and onward into the Golden Dawn tradition and modern ceremonial practice.

Mansions of the Moon calculates the Moon's precise ecliptic longitude using the astronomical algorithms of Jean Meeus and tells you which mansion it currently occupies, which angel governs it, and what influences are in play — tonight and every night.

The 28 mansions divide the ecliptic into equal arcs of 12°51', starting from 0° Aries. As the Moon completes its sidereal month, it passes through each mansion in turn. Each station has its own ruling angel, its own traditional effects drawn from Barrett's Magus (1801), and its own expanded guidance for modern practice.

FEATURES

• Real-time lunar mansion calculation from ecliptic longitude — not the approximate synodic age method, but proper positional astronomy

• All 28 mansions with ruling angels, traditional effects, zodiac signs, degree ranges, and alternative names from the Arabic tradition

• Moon phase display with phase-accurate visualisation and illumination percentage

• Expanded essays for every mansion — magical operations, historical notes on the Arabic-Latin-English transmission, and practical guidance for contemporary practitioners

• Visual mansion wheel showing the Moon's current position on the ecliptic, with zodiac signs colour-coded by element

• Browse and filter mansions by magical category: Travel, Love, Conflict, Healing, Prosperity, Captives, Buildings, and Discord

• Detailed essays on the three principal source texts — the Picatrix, Agrippa, and Barrett — tracing the chain of transmission from medieval Arabic courts to modern ceremonial magic

• Dark grimoire interface designed for the aesthetic of stone and candlelight, not the Llewellyn catalogue

THE SOURCES

The mansion names, angel attributions, and traditional effects are drawn from Francis Barrett's The Magus (1801), which transmits the system from Heinrich Cornelius Agrippa's Three Books of Occult Philosophy (1531), which in turn draws from the Arabic Picatrix (c. 1000 CE). All source material is public domain. The expanded interpretive essays are original.

THE ASTRONOMY

The lunar longitude calculation uses the principal periodic terms from Chapter 47 of Jean Meeus' Astronomical Algorithms, providing accuracy to approximately 0.3° — more than sufficient for mansion determination, where each mansion spans nearly 13°. No internet connection required. No location services. The Moon is in the same mansion for everyone on Earth at any given moment.

No ads. No tracking. No subscriptions. No in-app purchases. No data collection of any kind.

The grimoire is complete.

### 3/5 — Useful but...

*2013-11-17*

This works beautifully, but as a pagan checking my ephemeris and the degrees with the correlating information the mansions within this app do not seem to match so I am curious as to where the developer retrieved the information. If this was clarified and/or the mansion Angel plus the other names were given for each day per month. I would rate this 5 stars and pay up to 10.00 for the app.

### 1/5 — A GREAT IDEA BUT PRESENTLY USELESS

*2012-11-21*

I am delighted someone thought to do a Mansions of the Moon app.  When the bugs are fixed, this will be terrific.  As it stands, it's useless.  It does not calculate the current moon mansion accurately for either the Sidereal or Tropical zodiacs.  In order to be a useful app, the following needs to be fixed: (1) the app needs to be able to calculate the current mansion for a specific locality and date in GMT; (2) the app needs to be user selectable for the Sidereal or Tropical zodiacs; (3) the app needs to refer to each Mansion by number; adding additional information - Arabic name, lord of the mansion, and interpretative data, would be great.  Less importantly, while Barrett's Magus -- the source of the interpretative data -- is fine as far as it goes, the Mansions material in the Magus is a rehash of earlier sources, particularly Picatrix and Agrippa.  I might have used a combination of these -- but I concede this is hair splitting.  My other comments are substantive -- and I wouldn't advise wasting money on this app until they get these problems fixed.

### 3/5 — Finally! A mansions of the moon app.

*2012-06-26*

Im very happy to see an app that allows us to see the current mansion of the moon. However, I wish that the information wasnt so generic, and that the creators made it into a calender format so we can see past and future lunar mansions. I hope that you guys will update this app to its full potential, in a way that takes it from an okay app to an amazing one. :)

### 1/5 — Mansion app

*2012-01-07*

Good idea, if it worked. Frozen, partial page, reinstalled three times. Not impressed, ESP. Since its not free. I was also blocked from reporting a problem!

## Version history (last 5 releases)

### 4.1 — 2026-04-03

Fixed rendering code for Moon's disk near totality.

### 4.0 — 2026-03-23

Complete rewrite from the ground up. Version 4.0 is an entirely new app — nothing survives from the 2011 original except the data from Barrett's Magus and the mission to put the lunar mansions in your pocket.

What changed? Everything.

ASTRONOMY
The original app calculated the moon's synodic age and divided by 28 to calculate the current mansion. This worked most of the time, but synodic age drifts — the Moon's age doesn't map cleanly to its ecliptic position. Version 4.0 uses the Meeus algorithm (Astronomical Algorithms, Chapter 47) to compute the Moon's actual ecliptic longitude from 30 periodic terms, accurate to approximately 0.3°. The mansion is determined by where the Moon actually is, not by how old it approximately is.

CONTENT
The original had three screens: angel name, effects, zodiac sign. That was it. Version 4.0 includes expanded essays for all 28 mansions — magical operations, historical notes tracing the Arabic-Latin-English transmission, and practical guidance for contemporary practitioners. Three full essays on the source texts (the Picatrix, Agrippa, Barrett). Category filtering across eight magical domains. A visual ecliptic wheel. Moon phase with illumination percentage.

DESIGN
The Planewalker gothic font and pre-rendered moon PNGs are gone. The interface is now a proper dark grimoire — Palatino serif typography, a copper and bronze colour palette, procedural moon rendering with phase-accurate illumination, and the kind of considered aesthetic that makes you feel like you've opened a grimoire rather than an app. Stone and candlelight, not a Renaissance Faire stall.

TECHNOLOGY
Objective-C, nibs, and singleton patterns replaced with Swift, SwiftUI, and the Observation framework. No external dependencies. No network calls. No tracking. No ads. No subscriptions.

The grimoire is complete. Finally.

### 3.0 — 2013-07-19

* iPhone 5 Compatibility
* Updated Graphics
* Fixed Typo

### 1.1 — 2012-03-29

* Minor correction to lunar age calculation algorithm

### 1.0 — 2011-11-11
