28 lunar mansions (Agrippa)
Western · Esoteric
The 28 lunar mansions of the Arabic-Hellenistic tradition — documented by Heinrich Cornelius Agrippa and in the Picatrix — represent a distinct system of lunar timing, magical practice, and astrological correspondence that predates and differs structurally from the Vedic 27-nakshatra system.
What it is
The lunar mansions — known in Arabic as Manazil al-Qamar ('stations of the Moon') — are a system of 28 divisions of the celestial path travelled by the Moon in one sidereal month. The Moon moves approximately 12°–13° per day and thus passes through roughly one mansion each day. Each mansion corresponds to a specific region of the sky, a group of stars near the ecliptic, and a distinct magical or astrological attribution.
The Arabic-Western version of the lunar mansions was transmitted to medieval Europe principally through two sources: Heinrich Cornelius Agrippa's 'Three Books of Occult Philosophy' (Book II, Chapter 33-34 and the general lunar mansion chapter), drawing on earlier Arabic and Hellenistic sources; and the Picatrix (Ghayat al-Hakim, 'The Aim of the Sage'), an Arabic compendium of talismanic magic written around the 11th century CE that provides extensive mansion-by-mansion instructions for creating images, choosing times, and working with each mansion's angel and celestial quality.
This tradition is distinct from the Vedic 27-nakshatra system in several important respects: it uses 28 rather than 27 divisions, the starting point and star references differ, and the interpretive framework is embedded in medieval Hermetic and Neoplatonic philosophy rather than Vedic astrology. The two systems should not be mixed.
How it is calculated
Each of the 28 lunar mansions spans 12°51'25.7" of sidereal arc (360° / 28). The mansions are numbered beginning from approximately 0° Aries (sidereal) and proceed in the direction of increasing longitude. To find the Moon's current mansion, its sidereal longitude is divided by the mansion arc length, yielding the mansion number. Each mansion has a 'markab' (key star or star group near its beginning), an Arabic name, a Hermetic/talismanic image, a ruling angel in the Picatrix tradition, and specified effects on agriculture, travel, love, war, and commerce. Agrippa's Book II provides practical applications for each mansion in the context of natural magic.
What it reveals
The 28 Arabic-Western lunar mansions reveal a complete cosmological and magical map of the Moon's sky journey — one in which each daily station carries distinct spiritual, talismanic, and practical significance. Working with the lunar mansions in the Agrippa-Picatrix tradition involves aligning actions with the Moon's current mansion to harness its specific quality: some mansions are favourable for planting or travel, others for love and friendship, others for business, and certain mansions carry inauspicious qualities that classical authors advise avoiding for major undertakings.
In the revival of Renaissance magic and traditional Western astrology, the lunar mansions provide a layer of timing nuance that complements both planetary-hour work and solar-sign timing. The Picatrix's mansion-by-mansion magical images and instructions represent one of the most detailed surviving systems of lunar talismanic astrology from the Arabic-medieval transmission, offering practitioners a rich symbolic vocabulary grounded in the actual motion of the Moon through the stars.
Frequently asked questions
How are the 28 Arabic lunar mansions different from the Vedic 27 nakshatras?
While both systems divide the Moon's monthly path into approximately equal segments, they differ in several ways: the Arabic system uses 28 divisions, Vedic uses 27 (with the optional 28th Abhijit nakshatra). The starting points, star references, interpretive frameworks, and applications are entirely different — the Arabic system is embedded in Hermetic-Neoplatonic and Islamic magical philosophy, while the Vedic system is part of Jyotish's Parashara tradition. The two systems must not be mixed.
What is the Picatrix and why is it important for lunar mansions?
The Picatrix (Arabic: Ghayat al-Hakim, 'The Aim of the Sage') is an 11th-century Arabic compendium of talismanic magic translated into Latin in 1256. It is the most comprehensive surviving source for the Arabic lunar mansion tradition, providing mansion-by-mansion descriptions, talismanic images, timing instructions, and applications for agriculture, medicine, love, war, and commerce. It is a foundational text for the revival of traditional Western magic and stellar astrology.
Are the lunar mansions still used in modern Western astrology?
Their usage declined sharply after the Renaissance but has been revived in the 20th and 21st centuries through the renewed interest in Renaissance magic and traditional Western astrology. Today they are used by practitioners of electional astrology who want additional timing nuance, and by scholars and practitioners of traditional Western talismanic magic following the Picatrix and Agrippa.
