A 10th-century astrologer in Baghdad would not cast a talisman without first consulting the moon’s station among the 28 mansions. If the moon stood in Al Nathrah, he might set aside the work for another night. That mansion, the seventh of the Arabic lunar stations, carries a name that means “the gap” or “the open mouth” of the lion. Al Nathrah is one of the 28 lunar mansions (manazil al-qamar) used in Arabic astrology and magic, corresponding to the stars that form the head of Leo. Its influence is sharp, dual, and best approached with caution.
The moon passes through each mansion in roughly one day, covering about 12.86 degrees of its orbit. Al Nathrah occupies the first part of Leo, from about 0° to 13° of that sign. The stars that mark it are the sickle of Leo: Gamma, Zeta, Eta, Theta, and Mu Leonis. In the night sky, they trace the lion’s mane and snout. The name itself comes from the Arabic al-nathrah, meaning “the gap” or “the nostril” – the opening between the lion’s nostrils, or perhaps the gap between the stars themselves. The 10th-century astronomer Al-Sufi, in his Book of Fixed Stars, describes it as a small cloud-like patch near the lion’s head, a nebula visible to the naked eye.
Where does the lunar mansion system come from?
The 28 mansions predate Islam. Pre-Islamic Arab tribes used them for navigation, weather prediction, and agricultural timing. Each mansion marked a specific segment of the moon’s path, allowing a traveler to estimate the season by the moon’s position. The system was later absorbed into Islamic astrology and magic, where it gained a fixed set of correspondences: each mansion had a ruling planet, a specific influence, and a list of suitable talismanic operations.
The earliest surviving Arabic text to detail the mansions is the 9th-century Kitab al-Mawalid (Book of Nativities) by Abu Ma’shar, though the system appears in earlier Persian and Indian sources. The 11th-century scholar Al-Biruni devoted a chapter of his Book of Instruction in the Elements of the Art of Astrology to the mansions, listing their names, degrees, and effects. The Ghayat al-Hakim (known in Latin as the Picatrix), compiled in the 11th century, gives the most complete set of talismanic instructions for each mansion. That text is our primary source for how Al Nathrah was used in practice.
What does Al Nathrah symbolize?
The lion’s open mouth is not a passive image. It suggests both the power to devour and the vulnerability of a gap. In Arabic astrological tradition, Al Nathrah is considered a mansion of destruction and discord. The Picatrix states that its nature is “fiery and dry,” and that it is suitable for operations that cause separation, enmity, or the ruin of a place. A talisman made under this mansion, the text says, can be used to “cause discord between two friends” or to “destroy a house.”
But the same mansion also has a constructive face. Because it belongs to Leo, a fixed fire sign, Al Nathrah is associated with permanence and authority. Some sources list it as favorable for building foundations, planting crops that need deep roots, and making talismans for courage or leadership. The duality is not a contradiction. It reflects the nature of the lion itself: regal and destructive, protective and dangerous. The practitioner chooses which face to invoke.
How was Al Nathrah used in practice?
In electional astrology, the mansion’s influence determined whether an undertaking would succeed. Al Nathrah was considered unfavorable for marriages, partnerships, or any venture that required harmony. It was favorable for laying the cornerstone of a building, starting a long journey, or making a talisman intended to give the wearer authority over others.
The Picatrix gives specific instructions for a talisman made under Al Nathrah. The practitioner inscribes the image of a lion’s head on a piece of lead or iron, with the name of the mansion and the appropriate planetary sigils. The talisman is then buried at the foundation of a building to protect it, or carried to gain power in a dispute. The text also mentions using the mansion to cause illness or ruin, but it warns that such operations rebound if not performed with exact timing.
We do not recommend using Al Nathrah for harm. The tradition itself acknowledges the risk. The Picatrix advises that any operation under this mansion be performed with a clear intention and a protective ritual beforehand.
How does Al Nathrah compare to other lunar mansions?
The 28 mansions form a cycle, each with a distinct character. Al Nathrah follows Al Han’ah (the Brand), a mansion of healing and purification, and precedes Al Tarf (the Glance), which is associated with travel and commerce. The shift from Al Han’ah to Al Nathrah is abrupt: from gentle to sharp, from restorative to destructive. That contrast is intentional. The mansions mirror the moon’s own phases and the changing tides of influence.
In the Indian nakshatra system, the closest parallel is Ashlesha (the Embracer), which also falls in Leo and is considered a serpentine, dangerous nakshatra. But the two systems do not align exactly. The Arabic mansions begin at a different point on the ecliptic, and their names and meanings draw from Bedouin observation rather than Vedic mythology. Al Nathrah has no direct counterpart in Western astrological houses, though its position in Leo gives it some overlap with the 5th house of creativity and authority.
What do people get wrong about Al Nathrah?
The most common mistake is to treat Al Nathrah as purely malefic. It is not. The mansion’s reputation for destruction comes from its use in hostile magic, but the same energy can be channeled into protection, foundation work, and the assertion of legitimate authority. A builder who lays a foundation under Al Nathrah is not courting ruin; he is asking the lion’s strength to hold the walls.
Another misconception is that the Arabic mansions are identical to the Indian nakshatras. They share a common origin in the lunar cycle, but the names, boundaries, and interpretations differ. A practitioner who assumes they can substitute one for the other will get unreliable results.
Finally, some modern sources claim that Al Nathrah is associated with the “sneeze” of the lion, based on a misreading of Al-Sufi’s description. The word nathrah does mean “sneeze” in some contexts, but the astronomical tradition consistently uses it to mean “gap” or “nostril.” The lion is not sneezing. It is opening its mouth.

Al-NATH-rah, with a throaty “h” at the end. The Arabic nathrah has a voiced pharyngeal fricative that English speakers often approximate as a soft “h.”

The mansion is marked by Gamma, Zeta, Eta, Theta, and Mu Leonis – the stars that form the sickle of Leo. Gamma Leonis (Algieba) is the brightest.
Is Al Nathrah good or bad for talismanic magic?
It depends on the purpose. It is unfavorable for love or peace, but favorable for building, protection, and authority. Use it with clear intent and respect for its power.
How does Al Nathrah relate to the zodiac sign Leo?
It occupies the first 13 degrees of Leo, sharing the sign’s fiery, regal nature. It amplifies Leo’s qualities of leadership and strength, but also its potential for aggression.
Al Nathrah is not a mansion to approach lightly. It demands precision and purpose.

What you place inside it is your own choice.
