As we have seen with The Enochian Language and corresponding alphabet – it was once though that 17th Century Philosophers had ''discovered'' a ''hidden language'' only spoken by Angels (and perhaps even Demons). The resulting research was widely discredited. However, ''other sources'' brought forth information to supposedly add support to the Theory, with the publishing of what was known as ''The Celestial Alphabet''. Seen as being different from ''Enochian'', it involved 22 symbols used to produce various forms of ''Angelic Writing''. This too was seen as heresy. Hidden for many Centuries, The Alphabet was said to have been adapted by Folk Magic as a form in Invocation (Prayer) of Summoning.
