Consecration of the Sigillum Dei Aemeth

The Sigillum Dei Aemeth (the Seal of God, of Truth) is the central diagram of the Sworn Book of Honorius, and arguably its single most influential contribution to later ceremonial magic: centuries after the Sworn Book was compiled, John Dee had a version of this same seal constructed in wax as the physical foundation of his own angelic workings. The seal is built from two concentric circles enclosing a heptagon, within which sits a central pentagon inscribed with a Greek Tau cross and the divine names "El" and "Ely." The points of the heptagon carry the names of the seven archangels, and the outer band between the circles encodes the seventy-two-fold Name of God, the great Name derived by the Qabalists from three verses of Exodus.

Where the Rite of the Hundred Sacred Names purifies the vessel, the Sigillum Dei Aemeth is the instrument that vessel then wields. The Sworn Book presents it as the operator's primary talisman for angelic communion — a seal so laden with names of power that it can serve as protection, as a focus for scrying and vision, and as a key for calling upon the celestial intelligences whose names it bears. Constructing the seal is itself an act of devotion: every line, name, and letter must be copied with care, understanding, and reverence, for the seal's power in this tradition is inseparable from the operator's comprehension of what is being inscribed.

Once drawn and consecrated, the Sigillum Dei Aemeth becomes a standing tool rather than a single-use talisman — kept upon the altar, it is the seal before which the angelic invocations of the Sworn Book, including the invocation of the seven planetary archangels, are properly performed.
