Satariel was the 17th Watcher of the 20 leaders of the 200 fallen angels that are mentioned in an ancient work called the Book of Enoch. The name is believed to be of Babylonian origin a combination of shetar and el (God) with the name meaning "side of God". Michael Knibb believes the name to mean "Moon of God" or "Dawn of God" based on the Ge'ez copies of the Book of Enoch.
