Geomancy ("earth divination") is a method of divination that interprets markings on the ground or the patterns formed by tossed handfuls of soil, rocks, or sand. The most prevalent form of divinatory geomancy involves interpreting a series of 16 figures formed by a randomized process that involves recursion followed by analyzing them, often augmented with astrological interpretations.
Once practiced by people from all social classes, it was one of the most popular forms of divination throughout Africa and Europe in the Middle Ages and the Renaissance. Books and treatises on geomancy were published up until the 17th century when most occult traditions fell out of popularity. The Hermetic Order of the Golden Dawn curriculum currently includes geomancy in its study curriculum.
The shield chart most likely provided an early visual guide to generating the figures, and the interpreted answer would center on the fifteenth and sixteenth figures, the Judge and Reconciler. Skilled geomancers observe the whole chart, interpreting (among other things) meanings of the figures based on where they place in the chart, the numerical significance of the total points, and the similarities produced by added figures. Generally, the Judge represents the answer to the question, the Right Witness describes the querent's side of the query, the Left Witness represents the quesited's side, and the Reconciler represents the effect of the outcome (or Judge) upon the querent. The skilled geomancer can dedeuce root causes to the situation, hidden influences, the outcome and its aftermath, and general trends and events in the querent's life through interpreting the chart.
One division of the shield chart for interpretation involves triplets of the figures called triplicities. Each triplicity contains two of the Mothers or two of the Daughters and the Niece that results from them. They can be interpreted in a manner similar to the Witnesses and Judge, in that the right parent represents the past, the child the present, and the left parent the future; another way to interpret such a triplet views the right parent as the querent's side, allies, resources, and opinions, the left parent as the quesited's side, and the child as the interaction of the two sides.
