Enochian

"Enochian is an occult or angelic language popularised by John Dee and Edward Kelley in the 16th century. Dee and Kelley claimed that it was revealed to them by angels, though most contemporary practitioners of magick consider it a constructed language. The name "Enochian" is a reference to the Book of Enoch, a pseudepigraphal text and a major source of Judeo-Christian angelology.

Enochian, and the magickal system that Dee and Kelley based on it, were incorporated by Aleister Crowley as part of his popular and influential system. It is also popular in Hermetic Order of the Golden Dawn, from which Crowley learned it, and in the Aurum Solis. In 1969, Anton LaVey published The Satanic Bible that consisted of dark reinterpretations of the 19 Enochian Keys, presented in both English and Enochian transliterated to Latin characters.

Perhaps the most important student of Enochian at the turn of the 21st Century was the late Benjamin Rowe, also known as "Josh Norton", a self-taught ceremonial magician who wrote many papers on the use of Dee and Kelley's magical system." -
