The text begins with a legendary account of how King Solomon subdued seventy-two infernal kings, dukes, princes, and prelates, sealing them in a brazen vessel together with their legions before casting them into a deep lake in Babylon. Following this historical prelude, the manual sets forth a sophisticated psychological and ritual framework for ceremonial magic. The editor argues that the perceived spirits and their manifestations are not independent external entities, but rather specific, alterable portions of the human brain stimulated through the precise sensory apparatus of the ritual. The physical components of the operation—the geometric circle and triangle, the fumigations, the divine names, and the intricate seals worn as lamens—act as precise physiological triggers designed to establish absolute mental control and awaken latent faculties.
The core of the work consists of the classified catalogue of the seventy-two spirits. Each entity is meticulously described with its specific rank, the number of infernal legions under its command, its visual appearance upon evocation, and the particular offices it fulfills. These duties range from teaching philosophy, mathematics, and liberal sciences to discovering hidden treasures, revealing past and future events, restoring lost dignities, and procuring friendship or love. Alongside each description stands the unique linear seal or character that must be faithfully inscribed upon the appropriate metal corresponding to the spirit's planetary attribution.
To achieve successful evocation without succumbing to madness, terror, or destruction, the operator must adhere to strict ritual preparations. These include personal purification, the proper observation of the moon's age, and the wearing of specific vestments, such as a linen robe and a lion-skin girdle inscribed with divine names. The practitioner steps inside a consecrated nine-foot circular boundary and directs the spirit to appear within a designated triangular space outside the circle, armed with the protective magical ring and the pentacle of Solomon.
The ritual sequence proceeds through a graded series of invocations and constraints. The operator begins with standard conjurations making use of powerful divine names such as Tetragrammaton, Adonai, and Primeumaton. If the spirit proves obstinate or delays its appearance, the work escalates through the invocation of the cardinal kings who govern the entity, the general curse known as the spirits chain, and ultimately the conjuration of the fire wherein the spirit's seal is placed into a stinking box and subjected to symbolic destruction. Once the entity manifests in a fair and comely shape, the operator welcomes it respectfully, states the desired commands, and finally grants a formal license to depart in peace before closing the circle.
