One experience that may have been pivotal was Tolkien's professional work on a Latin inscription at the temple of Nodens; he was a god-hero linked to the Irish hero Nuada Airgetlám, whose epithet is "Silver-Hand", or in Elvish "Celebrimbor", the name of the Elven-smith who made the Rings of Power.
Sauron, powerful and ambitious, but humiliated by the fall of his evil master Morgoth at the end of the First Age, had evaded the summons of the godlike Valar to surrender and face judgment; he chose to remain in Middle-earth and seek dominion over its people.
[T 2] The exiled Númenóreans who survived, led by Elendil and his sons Isildur and Anárion, established the realms of Arnor and Gondor.
While the Nine are destroyed, the Three are rendered powerless; their bearers leave Middle-earth for Valinor at the end of the Third Age, inaugurating the Dominion of Men.
[T 1] Only after Sauron's defeat, when the One Ring was cut from his finger at the end of the Second Age, did the Elves begin to actively use the Three to ward off the decay brought by time.
[T 2] One by one, the Men fell to the power of the One Ring; by the end of the Second Age, all nine had become invisible ring-wraiths – the Nazgûl, Sauron's most terrible servants.
Each Ring enhances the "natural power" of its possessor, thus approaching its "magical aspect", which can be "easily corruptible to evil and lust of domination".
The Seven are used by their Dwarven bearers to increase their treasure hoards, but they do not gain invisibility, and Sauron was unable to bend the Dwarves to his will, instead only amplifying their greed and anger.
It grants the power of invisibility to its wearer, creating a moral dilemma, enabling people to commit injustices without fearing they would be caught.
[12][13] De Armas suggests that both Bilbo and Gyges, going into deep dark places to find hidden treasure, may have "undergone a Catabasis", a psychological journey to the Underworld.
[14] In Katz's view, Tolkien's story "demonstrate[s] various responses to the question posed by Plato: would a just person be corrupted by the possibility of almost unlimited power?
[16] "Magic rings are a frequent motif in fairy tales; they confer powers such as invisibility or flight; they can summon wish-granting djinns and dwarves", writes the Tolkien and feminist scholar Melanie Rawls.
She adds that they "identify the enchanted princess, hold the tiny golden key to the secret room, give one the power to transform oneself into any form — animal, vegetable, or mineral: duck, lake, rock or tree on a plain, and so escape the ogre.
[T 23][22] Intending to give Bilbo another adventure, he instead devised a background story around the Ring with its power of invisibility, forming a framework for the new work.
[T 26] He then briefly considered having Fëanor, creator of the Silmarils, forge the Rings of Power, under the influence of Morgoth, the first Dark Lord.
He settled on Celebrimbor, a descendant of Fëanor, as the Ring's principal maker, under the tutelage of Sauron, Morgoth's chief servant.
[25] Tolkien's posthumous works, including The Silmarillion, Unfinished Tales and The History of Middle-earth offer further glimpses of the creation of the Rings.
[28] According to Johann Köberl, Tolkien struggled with the notion of a "special status" for the Elven-Rings, and considered having The Three set free when the One Ring was destroyed.
[25] In an unused draft by Tolkien, Galadriel counselled Celebrimbor to destroy all the Rings when Sauron's deception was revealed, but when he could not bear to ruin them, she suggested that the Three be hidden.
[T 4][T 30] According to Unfinished Tales, at the start of the War of the Elves and Sauron, Celebrimbor gave both Narya and Vilya to Gil-galad, High King of the Noldor.
Gil-galad later entrusted Vilya to his lieutenant Elrond, and Narya to Círdan the Shipwright, Lord of the Havens of Mithlond and leader of the Falathrim or "People of the Shore".
Tolkien noted in his letters that the primary power of the Three was to "the prevention and slowing of decay", which appealed to the Elves in their pursuit of preserving what they loved in Middle-earth.
[1][T 31] As changeless beings in a changing world, the Elves who remained in Middle-earth relied on the Three to delay the inevitable rise of the Dominion of Men.
Since they wanted the bliss and perfect memory of Valinor, yet to remain in Middle-earth with their prestige as the fairest, as opposed to being at the bottom of the hierarchy in the Undying Lands, they became obsessed with "fading".
[31][32] While Tolkien denied that The Lord of the Rings was an allegory, he stated that it could be applied to situations and described it as an examination of "placing power in external objects".
Hood notes that while Gandalf, as one of the supernatural Maiar sent from Valinor, is "remarkably unlike an elf",[33] he is the character who most closely combines the angelic and the sacrificial among the wielders of the Three Rings.
[36] The Tolkien illustrator Alan Lee, employed as a conceptual designer for the films, had a cameo as one of the nine human Ring-bearers who later became the Nazgûl.
[37] The One Ring was shown to have the ability to adjust in size to the finger of its wearer, such as when it became smaller to fit Isildur (Harry Sinclair).
[40] In the concluding film The Battle of the Five Armies (2014), Galadriel (Blanchett) reveals Nenya in rescuing Gandalf (McKellen) from Sauron (Benedict Cumberbatch), aided by Saruman (Christopher Lee) and Elrond (Weaving), who is wearing Vilya, the Ring of Air.
[41] In the 2014 video game Middle-earth: Shadow of Mordor, the wraith-like spirit of Celebrimbor (fused with the body of the Ranger Talion) recalls how Sauron had deceived him into forging the Rings of Power.
