Turiel, Tûrêl (Aramaic: טויאלר, Greek: Τονριήλ) in later translations was the 18th Watcher of the 20 leaers of the 200 fallen angels that are mentioned in an ancient work called the Book of Enoch. The name is believed to originate from tuwr, el (God) meaning "rock of God". The translation taken from Michael Knibbs work on the Ethiopic Book of Enoch is "Mountain of God" or "Rock of God".
