One Ring

One of the most powerful artifacts ever created in Middle-earth, the One Ring was crafted by the Dark Lord Sauron in the volcano known as Mount Doom during the Second Age. His intent was to concentrate and enhance his own power, and to exercise control over the other Rings of Power, which had been made by Celebrimbor and his people with Sauron's assistance. In this way, he hoped to gain lordship over the Elves and all of the other races in Middle-Earth.

To accomplish this goal, Sauron knew that the One Ring would need to contain an extraordinary amount of power. As such, he concentrated within the Ring a great part of his own fëa (soul). In this way, Sauron's fate became bound to that of the One Ring. If it were damaged or destroyed, so to would be the portion of Sauron's fëa contained in it.

It was also known as the Ruling Ring, the Master Ring, the Ring of Power, and Isildur's Bane.

History


After its original forging (about SA 1600), Sauron attempted to use it to subjugate the Elven wielders of the other Rings. However, when Sauron placed the Ring on his finger, the Elves were immediately aware of him. Correctly assuming that Sauron's intent was to gain lordship over them, the Elves removed their Rings and put themselves beyond his influence. Infuriated that his plan had been thwarted, Sauron marshaled his armies to seize the Rings of Power by force. The conflict, which became known as the War of the Elves and Sauron, began in SA 1693. Initially, the war went very well for Sauron. He captured Eregion in short order and took back the Nine Rings that were kept there, and captured Celebrimbor, the maker of the Elven Rings of Power. He tortured Celebrimbor until he divulged the location of the Seven Rings. Celebrimbor died under torment by Sauron, refusing to reveal what he had done with the Three Rings, which he valued most. After the destruction of Eregion, Sauron was able to conquer most of western Middle-earth fairly quickly, driving the Ñoldor under Gil-galad to the Havens and besieging Imladris. But in SA 1700, as the Elves were nearing defeat, Tar-Minastir of Númenor led a great armada to Middle-earth and, together with Gil-galad, completely destroyed Sauron's armies, forcing Sauron to return to Mordor to regroup.

In SA 3261, Ar-Pharazôn, the last and most powerful of the Kings of Númenor, landed at Umbar at the head of an even more gigantic army to do battle with Sauron, in contention of Sauron's self-proclaimed title as Overlord of Middle-Earth and King of Men. The sheer size and might of the Númenórean army was enough to cause Sauron's forces to flee. Understanding that he could not overcome the Númenóreans through martial might, Sauron surrendered to Ar-Pharazôn and was taken back to Númenor as a prisoner. However, Sauron's surrender was both "voluntary and cunning", allowing him to gain access to the people of Númenor. The Elves had not revealed to the Númenóreans the existence of the Rings of Power, and so Ar-Pharazôn was unaware of the One Ring's existence and capabilities. Ascending rapidly to become the King's most trusted councilor, Sauron was able to use the Númenóreans' fear of death as a way to turn them against the Valar, and toward worship of Melkor.



Although Sauron's body was destroyed in the Fall of Númenor, his spirit was able to bear the Ring back to Middle-earth and he wielded it in his renewed war against the Last Alliance of Elves and Men between SA 3429 and 3441.

The Ring was cut from Sauron's hand by Isildur at the end of the Siege of Barad-dur in SA 3441, and he in turn lost it in the River Anduin (at the Gladden Fields) just before he was killed in an Orc ambush (TA 2). Since it indirectly caused Isildur's death by slipping from his finger and revealing him to the Orcs, it was known in Gondor lore as Isildur's Bane.



The Ring remained hidden in the riverbed for almost two and a half millennia until a Stoor named Déagol discovered it while on a fishing trip. His friend and cousin Sméagol stole the Ring and murdered Déagol. Sméagol was changed by the Ring’s influence over several centuries into the creature known as Gollum. Gollum, after being exiled from his home, sought shelter far beneath the Misty Mountains. There he and it remained for nearly five hundred years, until the Ring abandoned him and fell off his finger.



As is told in The Hobbit, Bilbo Baggins found the Ring while he was lost in the caverns of the Misty Mountains. Shortly after discovering it, Bilbo came upon Gollum himself, who had intended to eat the lost Hobbit. Bilbo managed to get Gollum to agree to a riddle game to determine his own fate; if he lost, Gollum would get to eat him, and if he won, Gollum would have to show him a way out of the caves. Gollum lost the game, but had no intention of letting Bilbo leave. He went to retrieve the Ring in order to use it's powers of invisibility to help him kill Bilbo, but flew into a rage when he found it missing. Deducing that Bilbo had it from his last question— "What have I got in my pocket?"— Gollum chased him through the caves, not knowing that Bilbo had discovered the Ring's powers of invisibility and was following him to the cave's exit. At one point as he neared the exit, Bilbo was presented with an opportunity to easily kill Gollum, but relented out of pity for Gollum's wretched condition.

Bilbo escaped Gollum and the Orcs that inhabited the Misty Mountains by remaining invisible, and told a falsified account of his adventures to Thorin's company and Gandalf, claiming he had won the Ring as part of the riddle game. Gandalf, who was also travelling with the Dwarves, was suspicious of Bilbo's story and of the Ring itself, which he immediately recognized as one of the Great Rings of Power due to the retarding effects it had had on Gollum's aging process. Some few years after Bilbo's return to the Shire, Gandalf managed to coerce from Bilbo the real story of how the Ring had come into his possession. The truth, as it turned out, had been quite innocent and was so similar to Bilbo's fabrication that Gandalf saw no real reason why Bilbo would have lied about his story in the first place, save perhaps to put his claim to the Ring beyond any possible doubt. Gandalf quickly came to believe that the Ring had an "unwholesome" effect on its owner that set to work almost immediately, as it was not in Bilbo's nature to lie, particularly regarding something so apparently trivial. However, he saw no real danger in letting Bilbo keep the Ring despite the Hobbit's strangely possessive attitude towards it.



In TA 3001, Bilbo concocted a plan to leave the Shire for Rivendell, and both he and Gandalf had initially intended for Bilbo's nephew and adopted heir Frodo to inherit both Bilbo's estate and the Ring. As the time came for Bilbo to give it up however, he became extremely reluctant to pass the Ring to his nephew, and his obstinacy over the issue led Gandalf to confront him directly about the Ring. At this point, though Gandalf did not yet know exactly what the Ring was, he could tell that it was both evil and gaining a great deal of influence over his old friend. As such, he advised Bilbo in the strongest terms to give the Ring to Frodo. After a short, angry debate, Bilbo calmed down and managed to give up the Ring of his own free will. He then departed from the Shire, and Frodo came into possession of the Ring.

However, Bilbo's strangely hostile reaction to giving up the Ring had greatly disturbed Gandalf. Troubled by both his encounter with Bilbo and recent events in the world at large, Gandalf began to consider the possibility that the Ring might be more dangerous than he had first believed. He initially considered revealing his concerns to Saruman, the head of the White Council and the Istari. However, having grown wary of Saruman's pride, he decided to keep his own council for the time being. Instead, he considered finding and interrogating Gollum in order to help him further understand the nature of the Ring. He searched for news of Gollum, and managed to determine that Gollum had indeed left the Misty Mountains to locate the Ring. However, lulled by the fact that Saruman had revealed to the White Council on at least one occasion that the Ring was beyond finding, he decided to let Gollum be. This proved to be an unfortunate oversight on Gandalf's part, because Gollum's long possession of the Ring had incidentally left him open to an mental summons from Sauron, who was putting forth his power to draw as many evil beings as possible to Mordor to rebuild his forces. As such, Gollum was pulled away from his search for the Shire and came at last to Mordor.

Gollum was eventually captured while skulking around the borders of the Black Land, and was taken to the rebuilt Barad-dûr. Here, Sauron too recognized the effects of a Ring of Power on Gollum. As the other Rings were all accounted for, being in his possession, destroyed, or in the hands of the Elves, he knew that Gollum must have at some point possessed the One. Under torture, Gollum revealed the existence of Bilbo and the Shire.

Around this time, Gandalf requested that Aragorn and his compatriots, the Dúnedain Rangers, begin to keep an extremely close watch on the Shire, and they soon began to report that an inordinately large number of creatures not native to the Shire were being used to keep watch on it at someone's behest. Now extremely worried, Gandalf decided at last to locate Gollum. Gandalf requested of his close friend Aragorn that he should aid him in a hunt for Gollum. However, as Gollum was at the time in Sauron's custody, his search was in vain. After months of fruitless wandering, Gandalf gave up on finding Gollum, leaving the seemingly hopeless search to Aragorn. Desperate for information, he realized while thinking of Saruman's ring-lore that the only source from which he could have obtained his knowledge was some sort of account left by Isildur, as he was the only person ever to have possessed the Ring besides Sauron. Gandalf then traveled to Minas Tirith in search of any records Isildur might have left behind concerning the Ring. After a thorough search, he finally came across a short manuscript by Isildur concerning the Ring's properties, including an important note that the Ring, when made hot, seemed to manifest fiery writing upon its outer band. Armed with this knowledge, Gandalf began a return trek to the Shire when he learned that, against all odds, Aragorn had somehow managed to find and capture Gollum. Gollum then revealed that he had been to Mordor, and that Sauron now knew virtually everything that Gandalf knew about the Ring's location.

Gandalf then hastened to the Shire and confirmed his suspicions; the Ring was indeed the One. Knowing the Sauron would use every means at his disposal to get it back, Gandalf instructed Frodo to flee to Rivendell with it, as it was the closest safe haven. Gandalf had intended to accompany them, but was lured to Isengard and imprisoned by Saruman, who wanted the location of the Ring so that he could take it for himself. Before he had departed however, he had given a letter to Barney Butterbur, the innkeeper of the Prancing Pony in Bree with instructions that it was to be delivered to Frodo immediately. The letter contained a warning to Frodo that he needed to leave the Shire at once, and had also contained a bit of information about Aragorn, whom Gandalf had instructed to watch for the hobbits and aid them if he could. However, the letter was never delivered, and as such, Frodo delayed his departure in the hopes that Gandalf was simply late. Eventually however, Frodo decided that he could no longer wait, and with his companions, Samwise Gamgee, Peregrin Took, and Meriadoc Brandybuck set out without him for Rivendell. Their delay however, had allowed Sauron's servants, a number of strange, black-clad horsemen, to journey to the Shire and begin searching for the Ring. The hobbits had a few close encounters with these horsemen, but managed to stay out of their grasp. Within a few days, they reached the village of Bree and encountered Aragorn, who revealed to them that he knew of their quest and was a friend of Gandalf's. He offered to guide them to Rivendell, but the hobbits were wary of his intentions. Fortunately however, Butterbur revealed Gandalf's letter to the hobbit party and they accepted his offer. By then, Gandalf had managed to escape from Isengard, and had begun desperately seeking for Frodo. He quickly reached the Shire, and discovered to his dismay that Frodo had only left a few days before. Having intended for Frodo to have left weeks prior, he realized that Butterbur had almost certainly not delivered his letter. Furious, he arrived at Bree a mere day after the hobbits had left it, and learned from Butterbur that Aragorn had found them and was guiding them to Rivendell. Greatly comforted by this knowledge, Gandalf set out for Rivendell the next morning. With virtually no hope of finding Aragorn and the hobbits in the wilderness, Gandalf set out for Weathertop, hoping that Aragorn would make for it as well. However, he was attacked at the old ruins by all nine of the Nazgûl, and though he managed to fend them off, he was ultimately forced to flee. In fleeing, he managed to draw four of the Nine into pursuing him, hoping that it would give the hobbits a greater chance of reaching Rivendell.

While on route to Rivendell, Aragorn and the hobbits stopped for an evening at Weathertop, where they were attacked by the five Nazgûl that had not pursued Gandalf. During the attack, Frodo was gravely injured by the Witch King. However, after a fortnight's travel, and with the help of the Elven lord Glorfindel, both Frodo and the Ring were delivered safely to Elrond in Rivendell. There, a Council was convened, which incidentally included members of every free race in Middle-earth, to decide what to do with the Ring. It was eventually decided that the Ring needed to be taken to Mordor and cast into Mount Doom, where it could be destroyed. Frodo volunteered to carry the Ring there, and a company of eight companions were chosen to accompany him. The Fellowship of the Ring, as the group came to be known, began the long trek to Mordor, but Saruman's treachery prevented them from traveling through the Gap of Rohan. With the pass of Caradhras not traversable due to intense snow storms, the group was forced to trek through Moria. There, they encountered a Balrog and Gandalf fell with it into an enormous chasm. The rest of the Fellowship safely reached Lorien, where the Elven lady Galadriel bade them to rest and replenish their supplies. While there, she spoke to Frodo concerning the Ring, revealing that even she was not immune to the temptation to take the Ring and wield it. However, she overcame the pull of the Ring, and provided each of the members of the Fellowship with a personal gift, specifically tailored to the skills of each.

Shortly thereafter, the Fellowship was scattered when Frodo and Sam split off from the rest of the group after an Uruk-hai attack. They continued on to Mordor alone, while the rest of the Fellowship, including a reborn Gandalf, prepared for war against Sauron's forces. Alone and without any clear sense of how to reach Mordor, Frodo and Sam quickly became lost in Emyn Muil's jagged hills. There, they encountered Gollum, who had been shadowing them ever since Moria. Frodo and Sam managed to capture him, and after swearing an oath to serve the Ring's owner (in the immediate case Frodo), Gollum was ordered to lead the two hobbits to Mordor, as he had been there before and knew the way. Passing through the Dead Marshes, the hobbits came to the Black Gate and prepared to enter Mordor. However Gollum, learning only upon their arrival of Frodo's intent to actually enter Mordor, revealed that there was another way in; the pass of Cirith Ungol. On their way to the pass, the hobbits encountered Faramir and a group of Ithilien rangers. Learning of their goal, Faramir aided them, providing stores of food and water. Reaching the city of Minas Morgul, the hobbits began their climb up the winding stair to a long tunnel. Here, Gollum betrayed them, for inside the tunnel dwelt the monstrous spider Shelob, who sought to consume the two hobbits. Sam and Frodo nearly escaped, but Frodo was stung by Shelob and captured by her. Sam managed to drive the gigantic spider off, but believing that Frodo was dead, he took the Ring and resolved to finish the quest himself. However, Frodo had simply been paralyzed by Shelob's venom, which made it appear as though he had been killed. He was captured by a group of Orcs while he was unable to move but Sam, who had overheard the Orcs discussing Frodo's condition, followed them to the Tower of Cirith Ungol. Shortly thereafter, Sam managed to rescue Frodo in the aftermath of a mutinous battle among the Orcs who had captured him, which had resulted in nearly the tower's entire garrison killing each other. Returning the Ring to Frodo, the two began the arduous march to Mount Doom. After a few days, they managed to make it to the volcano, but were ambushed by Gollum. Fending the shriveled creature off, Frodo continued to the Crack of Doom. But throughout his quest, the Ring had continued to tighten it's hold on Frodo's mind. As he reached the Crack of Doom, Frodo claimed the Ring for his own and put it on. Sauron immediately spotted him and, realizing the magnitude of his folly, sent the Nazgûl on winged mounts to retrieve it. As fortune would have it however, Gollum, who had been spared moments before by Sam, attacked Frodo and bit the Ring and most of the finger it had been on off of Frodo's hand. Then, dancing with joy over retrieving the Ring, Gollum took one misstep and toppled over the side of a cliff into the Crack of Doom. There, the Ring was swiftly unmade, crippling Sauron's power and ensuring that he would never again threaten Middle-earth.

Effects of the One Ring


When a typical person put on the ring, he would be partly "shifted" out of the physical realm into the unseen realm, walking its threshold. A side effect (but usually the first effect noticed) of this was that it made the wearer invisible to physical beings like living men, but highly visible to other unseen beings like Ringwraiths. This "unseen world" was the world the Wraiths were forced to live in but it was also a world in which the Calaquendi held great power.

For mortals, the ring had several side effects, most of them negative. Perhaps the first was that the bearer of the Ring almost immediately began to develop an unusually strong attachment to it, and would be unwilling to give it up or abandon it. Like the other Great Rings of Power, it would extend the lifespan of a mortal who possessed indefinitely, but that person, as Gandalf put it, would not grow or obtain more life, but would merely continue, until every minute was an unbearable weariness. One potentially positive effect was that the Ring may have granted the wearer some understanding of the speech of evil creatures. While wearing the Ring, Samwise Gamgee was able to understand the Black Speech used by the Orcs of Mordor. It also sharpened one's senses, and allowed one to perceive otherwise hidden things according to the stature of whomever wielded it.

Gandalf held that if the Ring was worn too frequently, the wearer would become wraith-like over time and become entirely subsumed into the spirit world. The rate at which this occurred depended largely on the wearer's inner nature. Race also seemed to perhaps play some part in it, as Hobbits in particular seemed to "fade" rather reluctantly. Merely keeping the Ring without using it greatly slowed most of the negative effects of the Ring, but it could not do so indefinitely. Additionally, its owner did not need to wear it in order to benefit from its effects on aging; Bilbo and Gollum both hardly ever used the Ring, yet were both seen to age remarkably well (even in Gollum's case, though his lifestyle and extreme age warped his body in some ways). The circumstances of initially finding the Ring also seemed to play a profound role in how quickly the Ring's negative effects began to take hold of the bearer, as did the bearer's own disposition. Gollum, for instance, obtained the Ring by means of murdering his close friend, and as such the negative effects of the Ring on his mind in particular manifested relatively quickly. Bilbo, on the other hand, not only obtained the Ring simply by way of finding it by chance, but when confronted with an opportunity to slay Gollum mere minutes after finding it, he chose not to out of pity for Gollum's wretchedness. Due to this, the Ring had only just barely begun to negatively effect his mind even over sixty years of having it in his possession, and Bilbo was ultimately able to give it up of his own free will, which was next to impossible for anyone who had possessed the Ring for any length of time to do.



The Ring, being essentially an extension of Sauron himself, was evil in nature. It seemed to possess at least a limited will of its own, and could "call out" subliminally to other people, in an attempt to get them to pick it up or possibly kill the current owner. It was also capable of changing sizes and could easily slip off of a finger where once it had been tight, with no obvious explanation as to why. Frodo Baggins was warned by Bilbo of this oddity, and kept it on a chain to make sure it never got lost.

The Ring's power grew throughout Frodo's journey, particularly on the last stage of the quest when Sam and Frodo entered Mordor and approached Mount Doom, the place of the Ring's forging.

Besides a partial, if not complete, loss of sanity over time, there were possibly physical consequences of keeping the Ring, as Gollum had been physically ruined by the time of his death; emaciated, pale, and hideous to view. However, it is not certain whether or not this physical transformation was a direct result of the Ring itself, or simply a consequence of Gollum's subterranean lifestyle and the fact that he was nearly five times older than any halfling-esque creature could ever naturally age.

Powers
"War is upon us and all our friends, a war in which only the use of the Ring could give us surety of victory."

- Gandalf

The Ring's primary power was control over the other rings, including "mastery over [their] powers" and domination of the wills of their users. However, its effectiveness in this manner proved limited, as the wielders of the Three never used them while Sauron held the One, and the Dwarves to whom the Seven had been given proved too tough for Sauron's mental influence to take hold. By extension, the Ring also conferred the power to dominate the wills of other beings whether they were wearing Rings or not. However, this is its least accessible power, since it granted this ability in proportion to the user's natural capacity. Perhaps most usefully, the Ring was capable of augmenting the abilities and powers of whatever being held it. While someone like Frodo was granted only a very limited increase in his perceptiveness, a Maia, Elf or Númenórean of great stature would have their innate powers vastly augmented, and would be able to, in time, draw upon the full power of the Ring itself.

A mortal wearing the Ring was made effectively invisible except to those able to perceive the non-physical world, with only a thin, shaky shadow discernible in the brightest sunlight. Whether immortals would be made invisible by it is unknown. The only immortal being who ever wore the Ring was Tom Bombadil, over whom the Ring had absolutely no power whatsoever. However, Bombadil was unique in that regard, as both Gandalf and Saruman were susceptible to the Ring's influence, and Bombadil was anomalous in many other ways.

It might have also given its wielder the ability to read minds and communicate via telepathy, as Galadriel suggested to Frodo when he asked if he could learn to communicate telepathically as she did. On at least one occasion, the Ring sharpened its wearer's hearing at the expense of his visual acuity, and it may at that time have granted understanding of unknown languages.

Another power of the Ring was the ability to project a false vision of its wearer to observers. When Sam encountered an Orc in the Tower of Cirith Ungol while holding the Ring, he appeared to the Orc as a powerful warrior cloaked in shadow "[holding] some nameless menace of power and doom." The Orc was so terrified of this illusion upon the otherwise unintimidating Sam that it fled. Similarly at Mount Doom, when Frodo and Sam were attacked by Gollum, Frodo grabbed the Ring and appeared as "a figure robed in white... [and] it held a wheel of fire." In this scene, Frodo (or perhaps the Ring itself) spoke "with a commanding voice" foretelling the destruction of Gollum.

As it contained the better part of Sauron's native power, it seemed to exhibit a malevolent, but limited, form of sentience. While separated from Sauron, the Ring would strive to return to him, both by impelling its bearer to yield to Sauron or his servants, or by abandoning its possessor at key moments. For example, it slipped off of Gollum's finger when the time was right for it to be brought back into the world at large. Which means the Ring can change its size to adapt to fit the user's finger or to grow large enough to slip off the user's finger to find a new user and/or find its way to Sauron.

To fully master all of the Ring's abilities, a wielder of the Ring would need an extremely disciplined and well-trained mind, a strong will, and a high degree of spiritual development. Even for those with the necessary prerequisites it would have taken time to master the Ring's powers to the point at which they would be strong enough to overthrow Sauron, and, hypothetically, bring peace. While this is a tantalizing prospect for some, in the end, the Ring's inherent corruption would have twisted its bearer into another Dark Lord as evil as Sauron was, or worse, regardless of their intentions at the outset. This result was apparently inevitable no matter how well-intentioned the bearer, as even fellow Maiar like Gandalf feared to so much as possess the Ring lest it's power begin to take hold.

Despite its powerful qualities, neither the Ring's innate power nor its power over others was absolute. Three times Sauron suffered military defeat with it in his possession, first by Tar-Minastir in the SA 1700, and again by Ar-Pharazôn in SA 3262 when Númenórean power so overawed his armies that they deserted him. He was defeated militarily once more at the end of the Second Age by the Last Alliance of Elves and Men, which culminated in his personal defeat at the hands of Gil-galad, Elendil and Isildur. Tolkien indicates that this would not be possible during the waning years of the Third Age when the strength of the free peoples were greatly diminished. At that time there were no remaining heroes of the stature of Gil-galad, Elendil, Anárion, or Isildur; the strength of the Elves was fading and they were departing en masse to the Blessed Realm of Aman; the Dwarves had been driven out of Moria and would have been unwilling to concentrate their strength in any event; and the Númenórean kingdoms had either declined or been destroyed, and had few allies. In this environment, Sauron wielding the One Ring would have been able to conquer the entire continent with ease.

List of Ring-bearers
In total, the One Ring existed for c. 4867 years and was held by nine people, five of which were Hobbits. Sauron was by far the one to carry it for the most time (c. 1850 years), followed by Gollum (478 years), Bilbo (60 years), Frodo (17 years) and Isildur (2 years). Tom Bombadil also wore the ring on September 26, 3018 but was apparently unaffected by it. Of those who held the ring, only Samwise Gamgee, Bilbo Baggins and Tom Bombadil (who was not affected by the ring in any way) gave it up willingly. "Bearing" the Ring does not seem to be synonymous with merely touching or carrying it, since Gandalf refused to bear the Ring but was willing to handle it for a few seconds in Bag End.

Appearances




The Ring appeared to be made of real gold, but was essentially impervious to damage. Even Dragon-fire was said to be inadequate to harm the One. It could only be destroyed by someone whose smithcraft was as great as Sauron's, or by throwing it into the pit of the volcanic Mount Doom where it had originally been forged. Like the lesser rings forged by the Elves as "essays in the craft" before the Great Rings, it bore no gem, but when heated, it displayed a fiery tengwar inscription in Elvish Runes. The lines were later taken up into a rhyme of lore describing the Rings, but they were evidently part of the spell that imbued the One Ring with power, since the Elves heard Sauron utter the same words during the Ring's creation whereupon they took off their own Rings and foiled his plan.

The ring-inscription is in Black Speech, the language of Mordor, and is written in the script of Tengwar. The inscription symbolizes the One Ring's power to control the other Rings of Power.



Normally, the One Ring appears perfectly plain and featureless, but when cast into fire the inscription appears in fiery letters inside and outside the Ring. A transliteration appears, when Gandalf reads the Ring-inscription during the Council of Elrond. "Ash nazg durbatulûk, ash nazg gimbatul, ash nazg thrakatulûk, agh burzum-ishi krimpatul"

- The inscription in the One Ring

Roughly translated, the words mean:  One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them.

When the Ring was first forged, Sauron spoke these words aloud, and Celebrimbor, maker of the Three Rings of the Elves, heard him from afar and was aware of his now-revealed purposes. The inscription uses Elvish lettering because all forms of writing Tolkien describes at that time were invented by the Elves.

Some recent editions of The Fellowship of the Ring accidentally omit the first two clauses of this phrase from Chapter 2, an error that was corrected by the time of the 50th Anniversary editions. The first four lines of the verse introduce three of the races inhabiting Middle-earth, as well as the eponymous title character, the Lord of the Rings:

 Three Rings for the Elven-kings under the sky, Seven for the Dwarf-lords in their halls of stone, Nine for Mortal Men doomed to die, One for the Dark Lord on his dark throne In the Land of Mordor where the Shadows lie. One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them In the Land of Mordor where the Shadows lie.

Gandalf first learned of the Ring-inscription when he read the account that Isildur had written before marching north to his death and the loss of the Ring. When Isildur had cut the Ring from Sauron's hand, it was burning hot, and so Isildur was able to transcribe the inscription before it faded. When Gandalf subsequently heated the ring that Bilbo Baggins had found and passed on to Frodo the inscription appeared, the wizard had no doubt that it was the One Ring.

Fate of the Ring-bearers
Of the several bearers of the One Ring, three were still alive following the One Ring's destruction: Bilbo Baggins, Frodo Baggins, and Samwise Gamgee (Although it becomes six if you count Tom Bombadil, Gandalf, and Sauron, who he did not truly die according to Gandalf). Bilbo, having borne the Ring longest of the three, had reached a very advanced age for a Hobbit. Frodo suffered both physical and psychological scars from his strenuous quest to destroy the Ring. Samwise, having only briefly kept the Ring was affected the least and appeared to carry on a normal life following the Ring's destruction.

In consideration of the trials the Ring-bearers had endured, special dispensation was granted them by the Valar to travel to Tol Eressëa, the Elvenhome; though not the Undying Lands themselves, where it was hoped they could find rest and healing. At the close of The Return of the King, Bilbo and Frodo embark for the voyage to the West along with Galadriel, Elrond, and many of their folk, as well as Gandalf. Near the end of his life, Samwise is also said to have sailed to Eressëa. Tolkien in one of his letters described the process as a period of extended life and healing, after which, their spiritual scars cured, they would die in peace (if they so wished.) No mortal can set foot in the Undying Lands.

Other versions of the legendarium
When The Hobbit was written, Tolkien had not yet conceived the Ring's sinister back-story. Thus, in the first edition of The Hobbit, Gollum surrenders the Ring to Bilbo as a reward for winning the Riddle Game. However, as Tolkien changed the nature of the Ring to fit into the legendarium of Middle-earth, he realized that the Ring's grip on Gollum would never permit him to give it up willingly. Therefore, Tolkien revised this chapter in the second edition of The Hobbit, having Gollum offer to show Bilbo the way out instead of offering to give up the Ring. Tolkien then decided that the first edition's version of events was how Bilbo had originally told the story to Gandalf and the Dwarves of Thorin's company, rather than what had actually occurred.

Symbolism of the One Ring
Tolkien has always held that his works should not be seen as strict symbolism (he believed that an author telling a reader how to think or feel about a story was acting as a kind of tyrant as seen in The Letters of JRR Tolkien). The Andvarinaut in the Völsunga saga is considered to be one of the inspirations; though Tolkien himself credited many other myths that revolve around the separation of a part of oneself to grant immortality.

Trivia

 * The sequence in Magyk by Angie Sage where Septimus finds the Dragon Ring is oddly similar to when Bilbo finds the Ruling Ring.
 * The ring makes an appearance in the animated movie Shrek 2.
