1Claves Intelligentiarum: A Complete Practical Manual of Conjuration of the Planetary Intelligences by renowned author David Rankine throws open the gates of the grimoire tradition. For the first time the complete process of preparation, purification, conjuration, and the rationale for each step of the process is described in comprehensive detail, providing a much-needed entry point into the practice of grimoire conjuration.

This synthesis of Solomonic grimoire practices continues the evolution of the tradition by bringing those practices into the twenty-first century while remaining faithful to their roots. Additionally, the author includes new consecrations he created where they were missing from the tradition, as well as a new analysis of the triangle and its use.

As well as supplying a thorough foundation to the conjuration of the Planetary Intelligences, this material can also be used as a template and be built on for future conjuration work. At its heart, Claves Intelligentiarum is an acknowledgement and encouragement of the evolution of personal practice within the grimoire tradition.
