This is a practical handbook on geomancy — the divinatory art of generating figures from random dot-marks — issued under the authority of the A∴A∴, Aleister Crowley's magical order, in the early twentieth century. Its core content is a reference system of sixteen geomantic figures, each assigned to a zodiac sign, element, sex, planetary ruler, angelic genius, and planetary intelligence, followed by step-by-step instructions for casting a full geomantic chart: generating four "Mothers" from random lines, deriving Daughters, Nephews, Witnesses, a Judge, a Reconciler, and a Part of Fortune. The work then provides interpretation tables correlating paired Witness-Judge figure combinations against ten domains of inquiry — health, money, rank, property, marriage, sex of a child, illness, imprisonment, travel, and lost objects — giving verdicts from "Good" to "Evil" or specific outcomes. A notable tension runs through the text: its prefatory Zoroastrian epigraph explicitly condemns divination by birds and entrails as "mere toys" and "mercenary fraud," yet the handbook itself is an earnest technical manual for a comparable predictive practice. The editors openly state they have introduced deliberate errors and omissions to protect the material from misuse, with correct methods to be communicated only to vetted students — framing the printed text as an intentionally incomplete transmission. It sits squarely in the Western esoteric tradition of ceremonial magic, drawing on medieval Arabic-European geomancy while embedding it in a Thelemic ritual framework.
