Etymology: "Aethyrs" is the plural of "aethyr," and the singular has an unusual history. The term belongs to the system of Enochian magic devised in the 1580s by the English mathematician John Dee and his scryer Edward Kelley, who claimed to receive its angelic language in visions. Dee's system divides the cosmos into thirty "aethyrs," each a spiritual realm or plane ranked above the material world, and the word was his coinage for them rather than a survival from older English or classical sources. Its spelling and sound come from the Greek "aithēr," meaning the upper, bright air or the clear sky beyond the clouds, a sense that Dee and his successors drew on when they layered heavenly spheres above the earth. The word was later taken up by the occultist Aleister Crowley, who used the Enochian aethyrs in his own rituals, which helped keep the term alive among modern practitioners.
