The Shield Chart in Geomancy: A Traditional Practitioner's Guide
Master the foundational framework of geomantic divination
For years, I've practiced geomancy, first through the traditional Arabic method passed down in my family, then through my own study of Western geomantic traditions since 2019. Yet despite all the techniques, figures, operations, and chart interpretations I've learned—whether using a geomancy chart generator, DIY geomancy tools, or manual practices—one thing remains fundamental: the Shield Chart. It's the backbone of every reading, the living framework of geomantic divination, and yet many modern sources either gloss over it or complicate it unnecessarily.
Today, I want to walk you through how to cast a traditional geomantic chart step by step, focusing on the Shield Chart—not as a dry, mechanical process, but as an easy to learn guide, rich with esoteric symbolism and deep insight. Whether you're a beginner learning how to cast a geomancy chart manually or a seasoned diviner comparing Islamic geomancy and Renaissance-style geomancy, this complete geomancy chart tutorial includes long-tail keyword phrases, figures, and practical tips—using both old methods and modern geomantic software like my online geomancy chart generator.
What Is the Shield Chart?
Unlike other forms of divination, where each symbol is drawn independently, geomantic figures build upon themselves. We start with four Mothers, generated randomly (traditionally by marking lines in sand, soil, or with a stylus) as part of the manual method of casting a geomancy chart or through a geomancy chart generator. From these Mothers, we derive more figures using transposition, addition, and synthesis.
This framework is called a Shield Chart because its layout resembles a medieval heater shield. While European geomancers like Robert Fludd and Christopher Cattan sometimes omit the 16th figure (Sentence/Reconciler), in traditional Arabic geomancy—and in my practice—all sixteen positions matter. Even if you're using modern geomantic tools, learning how the Shield Chart works by hand reveals the symbolic system beneath.
Step-by-Step: How to Create the Shield Chart by Hand
1 The Four Mothers
These are the foundation of your geomancy chart. Generate them randomly using methods like the stick-and-surface method, or create them with a geomantic chart generator. Place them right to left in the top row:
- First Mother (far right)
- Second Mother
- Third Mother
- Fourth Mother (far left)
Example generation:
Albus, Acquisitio, Fortuna Minor, Fortuna Major
2 The Four Daughters
Each Daughter is formed by reading the Mothers' rows horizontally—executing a manual "addition"—just like you'd learn in a geomancy reading tutorial:
- First Daughter = top fire rows
- Second Daughter = second air rows
- Third Daughter = third water rows
- Fourth Daughter = bottom earth rows
In our example:
Fire rows (2, 2, 1, 2) → Albus
Air rows (2, 1, 1, 2) → Conjunctio
Water rows (1, 2, 2, 1) → Carcer
Earth rows (2, 2, 1, 1) → Acquisitio
These are placed below the Mothers. This is part of your DIY geomantic chart method.
3 The Four Nieces
Construct each Niece by adding two figures:
- First Niece = First Mother + Second Mother
- Second Niece = Third Mother + Fourth Mother
- Third Niece = First Daughter + Second Daughter
- Fourth Niece = Third Daughter + Fourth Daughter
Using our example:
Albus + Acquisitio = Caput Draconis
Fortuna Minor + Fortuna Major = Via
Albus + Conjunctio = Rubeus
This observation is a key component in casting a geomantic chart with meanings.
4 The Court: Witnesses & Judge
The Court represents the synthesis of all previous figures:
- Right Witness = First Niece + Second Niece
- Left Witness = Third Niece + Fourth Niece
- Judge = Right Witness + Left Witness
Application:
Caput Draconis + Via = Laetitia (Right Witness)
Rubeus + Fortuna Minor = Laetitia (Left Witness)
5 The Sentence / Reconciler (16th Figure)
Finally, we derive the Reconciler:
Reconciler = Judge + First Mother
In Renaissance-style geomancy and horary geomancy, this 16th figure is essential—and modern geomantic software calculates it automatically, but the symbolism is yours to appreciate.
Validating Your Shield Chart
Before interpreting your chart, perform these validation checks:
- Judge must have an even number of points
- At least one figure must repeat
- Three key sums must match
- First Niece + Judge
- Second Mother + Sentence
- Second Niece + Left Witness
These checks ensure your geomancy chart is accurate and valid—just like verifying a horoscope.
Why the Shield Chart Matters
Some practitioners treat the Shield Chart as a stepping stone to the House Chart. I don't. In my experience, the Shield Chart is the reading. The House Chart simply offers another lens. Whether you're using Islamic geomancy or Western occult geomantic systems, the figures and chart structure remain consistent.
Whether you learn the traditional manual method, or use a geomancy chart generator to facilitate, you're working within the same esoteric knowledge system practiced for centuries.
Modern Tools: Geomancy Chart Generator & Software
Technology offers powerful tools. That's why I built an online geomancy chart generator—a geomantic tool that:
- Automatically casts geomantic figures
- Generates Shield, House, and Reconciler figures
- Provides interpretative readings and symbolic meanings
- Allows you to save, download, or share charts via links
- Helps beginners learn while also aiding advanced diviners
This tool is great for:
- Absolute beginners learning how to cast a geomancy chart manually
- Practitioners archiving divination readings
- Students exploring symbolic systems
- Those comparing DIY geomancy charts with digital ones
It blends the manual method, the spiritual insight of traditional geomancy, and the convenience of modern geometric software.
Final Thoughts
Geomancy is both ancient ritual and living art. The Shield Chart isn't merely a diagram; it's a dynamic map of forces. Once I mastered the right-to-left order (common in Arabic practices), I understood why this structure endures.
Take the time to learn how to create a geomantic chart manually. Then enhance your practice with modern tools and geomancy generators. Whether you're learning how to do geomantic chart casting step by step, exploring Renaissance-style geomancy, or using digital support, combining old and new is the key.
The Shield Chart is where the magic begins. Master it. Use both the symbolic power of manual geomantic charts and the convenience of geomancy chart generator tools. Respect tradition. Use tools wisely. Divine insight will follow.
