LIT is the fifth 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, LIT, 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
LIT's three Parts are held by Lazdixi, governing Bactriane in what is now northern Afghanistan under King Olpaged of the tribe of Dan; by Nocamal, governing Cilicia on the south-eastern coast of Anatolia under King Alpudus of the tribe of Issachar; and by Tiarpax, governing Oxiana along the river now called the Amu Darya under King Zinggen of the tribe of Zebulun. Dee's own presentation of the thirty Aethyrs runs outward to inward, from the first toward the thirtieth; the now-standard practice of working the sequence in reverse, from the thirtieth toward the first, is Crowley's own imposition, following a model of ascent that Dee's material never proposes.
