BAG is the twenty-eighth 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, BAG, 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
BAG's three Parts are Labnixp, ruling Adumian, closely resembling the Adumea assigned ten Aethyrs earlier and generally taken to mean Idumea, under King Lavavot of the tribe of Gad; Poclsni, ruling Felix Arabia, Arabia Felix, the fertile south-western corner of the peninsula, under King Zarzilg of the tribe of Naphtali; and Oxlopar, ruling Metagonitidim, from Metagonitis on the Mauretanian coast, under King Zurchol of the tribe of Simeon. Pairs of near-identical names scattered across widely separated Aethyrs, as with Adumian and Adumea, are among the strongest internal evidence that the ninety-one accumulated across sessions rather than arriving as a finished whole.
