LEA is the sixteenth 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, LEA, 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
LEA's three Parts are Cucarpt, ruling Sauromatica, the land of the Sarmatians north of the Black Sea, under King Ziracah of the tribe of Reuben; Lauacon, ruling Ethiopia in the broad sixteenth-century sense of the word, under King Hononol of the tribe of Judah; and Sochial, ruling a Part called Fiacim with no known referent, under King Arfaolg of the tribe of Ephraim, who is given more Parts across the ninety-one than any other King. The list draws its identifiable names from the classical geographers rather than from the political map of Dee's own day, a pattern that holds across nearly the whole tabulation.
