ZIP is the 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, ZIP, 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
ZIP's Parts are Oddiorg, ruling Assyria under King Hononol of the tribe of Judah, a territory repeated twenty Aethyrs later among the Parts of RII; Cralpir, ruling Sogdiana around Samarkand and Bukhara under King Lavavot of the tribe of Gad; and Doanzin, ruling Lydia, the old Anatolian kingdom whose capital was Sardis, under King Zarzilg of the tribe of Naphtali. Since Dee compiled the whole table himself from the session records, such repeated territories appear to be original to the material rather than a copying error, one of five clear duplications across the ninety-one that the received text leaves entirely without comment.
