KHR is the twentieth of the thirty Aethyrs, or Airs, of the Enochian system, the thirty spiritual regions delivered to the mathematician John Dee and the scryer Edward Kelley in 1584, and named in the record Dee compiled from those sessions. Its three-letter name, KHR, was received letter by letter through Kelley's scrying.
Place in the system
Each Aethyr is said to contain three Governors among whom the ninety-one Parts of the Earth are divided.
The thirty Aethyrs are the raw gift of the Dee-Kelley sessions; the elaborate visionary content attached to them in modern practice belongs to a later layer, above all Aleister Crowley's The Vision and the Voice, his record of scrying all thirty Aethyrs in 1900 and 1909. The Aethyr is described here as an element of that documented historical tradition, studied as such, its entities not reified.
The three Governors
KHR's three Parts are Zildron, ruling a Part called Tolpam with no known referent, under King Gebabal of the tribe of Asher; Parziba, ruling Carcedoma, usually read as a form of Carthage though the identification is not secure, under King Hononol of the tribe of Judah; and Totocan, ruling Italia, Italy, under King Alpudus of the tribe of Issachar. The elaborate tarot, elemental and Kabbalistic correspondences attached to the Enochian system in modern practice come from the Golden Dawn's nineteenth-century synthesis under Samuel Liddell MacGregor Mathers, none of them present in Dee's own manuscripts.
