Enochian is an occult constructed language — said by its originators to have been received from angels — recorded in the private journals of John Dee and his colleague Edward Kelley in late 16th-century England. Kelley was a scryer who worked with Dee in his magical investigations. The language is integral to the practice of Enochian magic.
John Dee (pictured) recorded the Enochian corpus in his journals with the assistance of Edward Kelley as his scryer and collaborator.
A constructed language is a language whose phonology, grammar, and vocabulary, instead of having developed naturally, are consciously devised for some purpose, which may include being devised for a work of fiction. A constructed language may also be referred to as an artificial, planned or invented language, or a fictional language. Planned languages are languages that have been purposefully designed; they are the result of deliberate, controlling intervention and are thus of a form of language planning.
