 The name is believed to originate from "tuwr" "rock" and "El" "God", meaning "rock of God", while the translation taken from M. A. Knibb's work on the Ethiopic Book of Enoch is either "Mountain of God" or "Rock of God".There is a grimoire called "The Secret Grimoire of Turiel" in which the magician is given instructions on how to contact Turiel.It claims to have been written in about 1518, and that it may have been copied from something older.
