ICH is the eleventh 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, ICH, 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
ICH's Parts are Molpand, ruling Bithynia on the Anatolian shore of the Sea of Marmara under King Lavavot of the tribe of Gad; Usnarda, ruling Graecia, Greece itself, under King Zurchol of the tribe of Simeon; and Ponodol, ruling a Part called Lacia, read as Latium by some and Lycia by others with no way to decide between them, under King Hononol of the tribe of Judah. Crowley worked the Aethyrs in reverse of Dee's own ordering, from the thirtieth toward the first, beginning in 1900 in Mexico and reaching only the twenty-ninth before completing the full sequence in 1909 in the Algerian desert with Victor Neuburg; the record was published in The Equinox in 1911.
