How This Cast Is Built
A faithful, step-by-step implementation of the classical casting procedure.
Four Mothers
The first sixteen marks are reduced to odd or even rows, producing four mother figures.
Parity Combination
Daughters are read from the mothers; nieces, witnesses, and judge are made by row-wise odd/even combination.
Judge and Outcome
The fifteenth figure is checked for evenness, then the outcome is formed from the first mother and the judge.
Why Geomancy Belongs Here
It is not modern personality content. It is a rule-governed classical question system.
Geomancy is an older divinatory art known in the Arabic tradition as ilm al-raml, the science of sand. A question is reduced to a set of odd and even rows, and those rows generate a full shield chart by fixed procedure.
That is why it fits this site. Traditional Astrology already favors techniques where the calculation can be audited: sect, dignities, house rulership, planetary motion, and horary perfection. Geomancy has the same appeal. The first figures determine the rest; the witnesses determine the judge; the judge must pass a validity rule.
The Strict Rules
The result is derived, not improvised.
Odd or Even Lines
Each line count is reduced to one dot if odd, two dots if even. Four rows make one figure, and the first sixteen rows make the four mothers.
Daughters From Rows
The daughters are not separately chosen. They are extracted across the mothers: top rows form the first daughter, second rows form the second, and so on.
Combination by Parity
Later figures come from combining rows. Matching rows produce two dots; different rows produce one dot. This creates the nieces, witnesses, judge, and final outcome.
Judge Validity
The judge, the fifteenth figure, must have an even total. If the judge has an odd total, the cast is invalid and should be rejected rather than interpreted.
The Shield Positions
Sixteen places, each generated from the figures before it.
Mothers
Positions 1-4 are the only figures directly cast from line counts. They are the seed of the whole chart.
Daughters
Positions 5-8 are drawn from the rows of the mothers. They reveal what was already contained in the original cast.
Nieces
Positions 9-12 are generated by combining mothers and daughters, narrowing the chart toward judgement.
Witnesses
Positions 13 and 14 are the questioner and asked-about witnesses, representing the two sides brought before the judge.
Judge
Position 15 is the balancing figure. It must be even, and it carries the strongest summary of the cast.
Outcome
Position 16 reconciles the first mother with the judge, giving a final derived outcome rather than a new random sign.
Geomancy as a Rule System
A derived shield, not an improvised answer.
Geomancy answers through a shield chart derived from parity. The mothers, daughters, nieces, witnesses, judge, and outcome are generated by fixed rules, so the result can be inspected step by step.
The geomancy tool is best for seeing that shield logic directly. The main reading offer is a free traditional natal reading, with an optional one-time Complete Analysis.
Geomancy Questions, Answered
Common questions about geomancy readings and the shield chart.
What is geomancy?
Geomancy (Latin geomantia, Arabic ilm al-raml, "the science of the sand") is a classical divination method that answers a question from sixteen lines of odd and even marks. The marks form four mother figures, and fixed rules derive the daughters, nieces, witnesses, judge, and outcome into a shield chart you can inspect step by step.
Is this geomancy calculator free?
Yes. The geomancy shield chart calculator is completely free and needs no account or email. Enter your question and cast as many charts as you like.
How does a geomancy reading work?
You pose a clear question, then four mothers are generated from sixteen line counts (secure random, or your own marks). Reading the mothers by rows gives the daughters; combining pairs by odd/even parity gives the nieces, the two witnesses, the judge, and finally the outcome. The judge is the core answer, and a valid chart has a judge with an even number of points.
What are the 16 geomantic figures?
Via, Populus, Fortuna Major, Fortuna Minor, Conjunctio, Carcer, Tristitia, Laetitia, Albus, Rubeus, Puella, Puer, Caput Draconis, Cauda Draconis, Acquisitio, and Amissio — each a pattern of four lines with its own classical meaning and elemental nature.
Can I ask a yes or no question with geomancy?
Yes. Geomancy suits yes/no and either/or questions well. The judge gives the core answer and the witnesses show how the situation arrives there. Keep the question clear and about a single matter for the cleanest reading.
