Lunar Mansion

Definition

A lunar mansion is one of 28 stations marked out along the Moon's 27.3-day sidereal orbit — its path against the fixed stars. Together the 28 form a lunar zodiac, running in parallel to the familiar 12-sign solar zodiac. The Moon crosses one mansion about every 24 hours. The earliest Arabic mansions had uneven widths, each set by a particular fixed star; later Arabic and European astrologers smoothed them into equal segments of about 12°51' (one twenty-eighth of the circle). The system is used in Arabic, medieval Latin, and Renaissance European astrology and magic.

In Tradition

In Arabic-Persian and medieval Latin practice, the lunar mansions give astrologers a Moon-based framework for timing and elections — choosing favourable moments — separate from the solar zodiac. Each mansion carries its own meanings for elections and talisman-making, along with its own planetary, angelic, and elemental correspondences. Picatrix Book I Ch 4 lists the 28 regular mansions with electional guidance; Picatrix Book IV Ch 9 gives talisman instructions for each. Al-Biruni's Tafhim treats the mansions outright as a lunar zodiac sitting beside the 12-sign solar one.

In Practice

You find which mansion the Moon occupies at the moment of an election, then consult that mansion's guidance on whether the moment suits the activity in hand — a beginning, travel, construction, a marriage, a contract. For talisman magic, the practitioner times the consecration of an object so it falls while the Moon is crossing the mansion whose meaning fits the intended effect; mansion-specific materials, images, suffumigations (ritual incense), and invocations are then used. Modern traditional-revival practice (Warnock, Greer-Warnock) draws the per-mansion attributions from Picatrix, Agrippa, Al-Biruni, Ibn Arabi, Liber Lunae, and William Ramesey together into one working electional and talismanic system.

Historical Origin

The 28-mansion system has roots in pre-Islamic Arabian star-lore and appears as a developed astrological doctrine in Al-Biruni's Kitāb al-Tafhīm (c. 1029) and in the Latin Picatrix (c. 1256, translated at the court of Alfonso the Wise from the Arabic Ghāyat al-Hakīm, composed c. 1000 in Spain). Ibn Arabi assigns Arabic-letter correspondences to the mansions; Cornelius Agrippa, in Three Books of Occult Philosophy III.24, gives a Lord-and-Angel name for each.
