Tolkien's The Lord of the Rings (1954--55). It is described in an earlier story, The Hobbit (1937), as a magic ring of invisibility . In the sequel, The Lord of the Rings, Tolkien ascribes to the Ring a darker character, with malevolent power going far beyond conferring invisibility: it was created by Sauron the Dark Lord as part of his design to win dominion over Middle - earth .
