John Ronald Reuel Tolkien was an English writer and philologist. He was the author of the high fantasy works The Hobbit and The Lord of the Rings.
The Lord of the Rings is an epic high fantasy novel written by English author and scholar J. R. R. Tolkien. Set in Middle-earth, the story began as a sequel to Tolkien's 1937 children's book The Hobbit but eventually developed into a much larger work. Written in stages between 1937 and 1949, The Lord of the Rings is one of the best-selling books ever written, with over 150 million copies sold.
Der Ring des Nibelungen, WWV 86, is a cycle of four German-language epic music dramas composed by Richard Wagner. The works are based loosely on characters from Germanic heroic legend, namely Norse legendary sagas and the Nibelungenlied. The composer termed the cycle a "Bühnenfestspiel", structured in three days preceded by a Vorabend. It is often referred to as the Ring cycle, Wagner's Ring, or simply The Ring.
Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant, with an average radius of about nine times that of Earth. It has an eighth the average density of Earth, but is over 95 times more massive. Even though Saturn is almost as big as Jupiter, Saturn has less than a third its mass. Saturn orbits the Sun at a distance of 9.59 AU (1,434 million km), with an orbital period of 29.45 years.
In mathematics, rings are algebraic structures that generalize fields: multiplication need not be commutative and multiplicative inverses need not exist. Informally, a ring is a set equipped with two binary operations satisfying properties analogous to those of addition and multiplication of integers. Ring elements may be numbers such as integers or complex numbers, but they may also be non-numerical objects such as polynomials, square matrices, functions, and power series.
Gandalf is a protagonist in J. R. R. Tolkien's novels The Hobbit and The Lord of the Rings. He is a wizard, one of the Istari order, and the leader of the Company of the Ring. Tolkien took the name "Gandalf" from the Old Norse "Catalogue of Dwarves" (Dvergatal) in the Völuspá.
The Rings of Power are magical artefacts in J. R. R. Tolkien's legendarium, most prominently in his high fantasy novel The Lord of the Rings. The One Ring first appeared as a plot device, a magic ring in Tolkien's children's fantasy novel, The Hobbit; Tolkien later gave it a backstory and much greater power. He added nineteen other Great Rings, also conferring powers such as invisibility, that it could control, including the Three Rings of the Elves, Seven Rings for the Dwarves, and Nine for Men. He stated that there were in addition many lesser rings with minor powers. A key story element in The Lord of the Rings is the addictive power of the One Ring, made secretly by the Dark Lord Sauron; the Nine Rings enslave their bearers as the Nazgûl (Ringwraiths), Sauron's most deadly servants.
Many types of wrestling matches, sometimes called "concept" or "gimmick matches" in the jargon of the business, are performed in professional wrestling. Some gimmick matches are more common than others and are often used to advance or conclude a storyline. Throughout professional wrestling's decades-long history, some gimmick matches have spawned many variations of the core concept.

The rings of Saturn are the most extensive and complex ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material. There is still no consensus as to their mechanism of formation. Although theoretical models indicated that the rings were likely to have formed early in the Solar System's history, newer data from Cassini suggested they formed relatively late.
In professional wrestling, a battle royal is a multi-competitor match type in which wrestlers are eliminated until one is left and declared the winner. Typical battles royal begin with a number of participants in the ring, who are then eliminated by going over the top rope and having both feet touch the venue floor.
Gollum is a monster with a distinctive style of speech in J. R. R. Tolkien's fantasy world of Middle-earth. He was introduced in the 1937 fantasy novel The Hobbit, and became important in its sequel, The Lord of the Rings. Gollum was a Stoor Hobbit of the River-folk who lived near the Gladden Fields. In The Lord of the Rings, it is stated that he was originally known as Sméagol, corrupted by the One Ring, and later named Gollum after his habit of making "a horrible swallowing noise in his throat".
The One Ring, also called the Ruling Ring and Isildur's Bane, is a central plot element in J. R. R. Tolkien's The Lord of the Rings (1954–55). It first appeared in the earlier story The Hobbit (1937) as a magic ring that grants the wearer invisibility. Tolkien changed it into a malevolent Ring of Power and re-wrote parts of The Hobbit to fit in with the expanded narrative. The Lord of the Rings describes the hobbit Frodo Baggins's quest to destroy the Ring and save Middle-earth.
Sauron is the title character and the main antagonist of J. R. R. Tolkien's The Lord of the Rings, where he rules the land of Mordor. He has the ambition of ruling the whole of Middle-earth, using the power of the One Ring, which he has lost and seeks to recapture. In the same work, he is identified as the "Necromancer" of Tolkien's earlier novel The Hobbit. The Silmarillion describes him as the chief lieutenant of the first Dark Lord, Morgoth. Tolkien noted that the Ainur, the "angelic" powers of his constructed myth, "were capable of many degrees of error and failing", but by far the worst was "the absolute Satanic rebellion and evil of Morgoth and his satellite Sauron". Sauron appears most often as "the Eye", as if disembodied.
