Does anyone know about a person named Enoch Noir who was an archbishop from
Austria and was in the Russian Court in the 17th or 18th century

The Book of Enoch is the major source of Judeo-Christian angelology
and the name is therefore commonly associated with angels; the word
noir means dark or black.  Dark angel.  The name you provided is at
best a pseudonym, and at worst the person is entirely fictional. 
Where are you getting this name from?

Thank you for your response.  I got this in a letter from some psychic and
figured it was something fictional.  I'm not going to chase it anymore.  Where
would I find information on the Book of Enoch?
