Sauron's sight wasn't just physical; it was a magical, focused will, but physically limited by the curve of the Earth, allowing him to see across most of Mordor and surrounding areas like Gondor, though mountains often blocked direct views; his vision was sharper with the One Ring, letting him perceive minute details from afar, while at its most basic, his "Eye" was a metaphor for his overwhelming power and attention, able to pinpoint threats like the hobbits but often misled by distance and obstacles.
Frodo comes of age as Bilbo leaves the Shire. Frodo inherits Bag End and Bilbo's ring. Gandalf, uncertain about the origin of the ring, warns Frodo to avoid using it and to keep it secret. Frodo keeps it hidden for the next 17 years, and it gives him the same longevity and youthful appearance it had given Bilbo.
He actually never sees Frodo until Frodo declares that the Ring is his at the Crack of Doom. He knows someone's wearing it, he can feel that but he never sees who or what has it until the end.
It was said that few could endure its terrible gaze. The Eye was used as a symbol on armor and banners of Mordor, representing Sauron's quasi-omniscience. With it, Sauron searched for and tracked the paths of the Ring-bearer Frodo Baggins at the end of the Third Age.
Sauron already exists in both the Seen and Unseen world at the same time, so the Ring doesn't pull him into the Unseen world. That's what the Ring does - it doesn't really turn you invisible, it pulls you into another dimension of sorts.
Instead, we have to consider that Sauron, the original owner, is not human, but has a quasi-divine status. Therefore ownership of the Ring is subject to Divine Law. With this precedent in mind, many of the ambiguities clear up nicely. After numerous transfers by violence and trickery, Frodo is the true owner.
The Ring's effects
Inversely, the hobbits' good-naturedness and lack of ambition makes them less susceptible to the Ring's promises of power, as in Frodo and Samwise Gamgee, who are able to handle the Ring for extended periods of time.
while Sauron was more powerful than Gandalf in a direct comparison, their roles and methods were fundamentally different. Gandalf's strength was in enabling others to resist evil, while Sauron sought to dominate and enslave.
Sauron's Eye was an all-seeing entity that manifested above Barad- dûr. Sauron is portrayed in the Lord of the Rings films as having a height of 9'2” (2.79 m) based on an analysis of film frames. How tall is Sauron? Sauron is portrayed as being 9 feet 2 inches (2.79 m) tall in the Lord of the Rings films.
Sauron needed Gandalf out of the picture permanently, as he was the only enemy with the knowledge, leadership and determination to thwart him. His biggest mistake was ego. He succeeded by trickery, by his ability to deceive others. He conquered so much land that his ability to control became out of reach .
Despite his status among Sauron's servants being similar to that of the Nazgûl, the Mouth of Sauron was a living man whose early history was largely forgotten.
Gandalf does not WANT to touch the ring. Just as Galadriel resists the temptation to take it when Frodo offers it to her willingly. And all this because "Power Corrupts". Sauron and the Ring are allegories for the corruption that inevitably arises when too much power is concentrated in one place.
Gollum is a hobbit that is featured in The Lord of The Rings, where his story his primarily focused on his possessive love of the One Ring. The power of the ring causes an unusual extension of life and in Gollum's case caused him to live to around 500 years old.
As a Maia, Gandalf was an angelic being in human form, in service to the Creator (Eru Ilúvatar) and the Creator's 'Secret Fire'. He took on the specific form of an old man as a sign of his humility. His role was to advise but never to attempt to match Sauron's strength.
Tolkien's description of Gollum conforms to a Catholic – and Thomistic – account of envy, which is a “sadness of the soul”; and it is Gollum's unbearable sadness and his unquenchable desire for the one Ring that marks his character.
His task was to do the bidding of his masters and so when he proved unfaithful in doing that task his masters stripped him of his robes and gave them to one who would do their bidding. Gandalf is now the White, Saruman as he should have been.
Sauron was originally a Maia of Aulë the Smith; his name then was Mairon, meaning "the admirable." He learned much from Aulë in the ways of forging and crafting, becoming a great craftsman, and mighty in the lore of Aulë's people.
Gandalf is the same type of being (both are Maiar). Sauron was the disciple of Morgoth who is essentially a Satan-type character and the worst of beings. Gandalf (and the other 4 wizards) were sent by the Valar (Morgoth's equals but good) to combat Sauron's evil.
Could he carry the ring for a short time? Yes. But like all other elves his good intentions would be twisted and corrupted by the ring's influence, and he would not want to be parted from it.
So much of what makes LOTR great as a piece of literature worked against being able to tell this story through film. Narration-heavy, a huge amount of worldbuilding, interweaving stories, and many, many characters.
They were both sort of mean and greedy. The Ring coming between them simply exploited (in its way) and exacerbated their mean natures briefly. (Briefly because Smeagol promptly murdered Deagol to gain the Ring.) And because Smeagol gained his Precious through murder it didn't take much for the Ring to corrupt him.
Exclusive worldwide rights to motion picture, merchandising, stage and other rights in certain literary works of J. R. R. Tolkien including The Hobbit and The Lord of the Rings were sold by Tolkien himself to United Artists in 1969, reportedly for a small amount, and are currently owned by Middle-earth Enterprises ( ...
It tells you why right in the book, Sauron releases him because he knows Gollum will go after the ring, and can be watched, leading Sauron to the ring.
Sauron's rise to power in the Second Age is portrayed in the Amazon prequel series The Lord of the Rings: The Rings of Power. He first appears disguised as the non-canonical human character Halbrand, and then in the second season as Annatar (a canonical alias of Sauron), both played by Charlie Vickers.
