According to Dee's journals, Angelical was supposed to have been the language God used to create the world, and which was later used by Adam to speak with God and the angels, and to name all things in existence. After his Fall from Paradise, Adam lost the language and constructed a form of proto-Hebrew based upon his vague memory of Angelical. This proto-Hebrew, then, was the universal human language until the time of the Confusion of Tongues at the Tower of Babel. After this, all the various human languages were developed, including an even more modified Hebrew (which we know as "Biblical Hebrew"). From the time of Adam to the time of Dee and Kelley, Angelical was hidden from humans with the single exception of the patriarch Enoch who, according to the angels, recorded the "Book of Loagaeth" (Speech from God) for humanity. The book was then lost again in the Deluge of Noah.
