RII is the twenty-ninth 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, RII, 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
RII's three Parts are Vastrim, ruling Assyria, already assigned a Part twenty Aethyrs earlier, under King Hononol of the tribe of Judah; Odraxti, ruling Africa, given here as a whole despite the list elsewhere dividing the continent into Numidia, Getulia, Cyrenaica, Marmarica and Mauretania, under King Zarnaah of the tribe of Manasseh; and Gmziam, ruling Bactriani, Bactria, assigned a Part twenty-four Aethyrs earlier under the spelling Bactriane, under King Arfaolg of the tribe of Ephraim. Since Dee compiled the whole tabulation himself, such repetitions belong to the material rather than to later copying, whatever finally explains them.
