LIN is the twenty-second 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, LIN, 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
LIN's three Parts are Ozidaia, ruling Apulia, the heel of Italy, under King Arfaolg of the tribe of Ephraim; Paraoan, ruling Marmarica, between Cyrenaica and Egypt, under King Olpaged of the tribe of Dan; and Calzirg, ruling Concava Syria, the hollow Syria of the classical geographers, under King Arfaolg again. Crowley's vision of this, the twenty-second Aethyr, is recorded like all thirty in The Vision and the Voice, first published in The Equinox in 1911; it documents what he saw approaching the Aethyr already carrying a Kabbalistic structure in mind, and is a source about early twentieth-century magical practice rather than a commentary on Dee's own table.
