Throughout Tolkien's works it is evident that his works are relevant to the motifs of Mythology and legend. He mainly draws information form Norse and Christian mythology but there are links to Greek traditional mythology.
We see connections in the heroes and villains, the supernatural, The journey, the trial, the struggle, the transformation and the homecoming. In traditional stories it is always the hero is good and the Villain is evil. This story is no exception, the fellowship is good and Sauron and Saruman are evil. The proof for Sauron is that it states that he poured all his evil and malice into the one ring and the one ring is the most evil object. Saruman is like the puppet of Sauron and only is evil because of his greed and lust for power.
The heroes are pure and good overall and fight for justice and what they believe in.
They push forward to destroy the one ring so that Sauron's reign of terror and his attack will end. In this book the main Heroes are Gandalf, Aragorn, Legolas, Gimli, ThÃÂ©oden, and Haldir. The push forward only to protect the innocent from the army of Saruman. The main villain in this book is not Sauron but Saruman; he has amassed a large army bent upon killing all men.
There are many forces and power, on the good side there is providence in that Gandalf only just gets there in time, like in the Ragnarok when the other races only just in time came to help defeat the giants. Gandalf's supernatural return s liked to Christian mythology as Christ rose more glorious in appearance as well.
There are not many sacred and enchanted objects but Aragorn's sword Narsil that although is not magic is it similar to king Arthur's first sword...
