LotR -- Book 4 - Chapter 09 - Shelob’s Lair

[Guinevere]

This chapter is full of suspense - the description of the tunnel is incredibly creepy and full of foreboding. The utter darkness and the stench are something which of course couldn't be conveyed to the film and I think the scene is much more effectful in the book. It reminds me somehow of a "ghost-train" or "tunnel of horror" at a fun fair, especially the unseen things brushing their heads and hands in the dark.
I note that in the tunnel, Frodo is the one who is more resolute and couragious.

Anyway, one thing that really stood out to me was how Sam praised Frodo for his heroic act of chasing Shelob away, saying that it would go down in song. Little did he know that his own actions in the following moments would completely overshadow those of Master Frodo

Several movie-oriented LotR-fans I know don't even remember Frodo's bravery! But I just love this scene: (probably now even more, because it is such a contrast to the helpless movie-Frodo...)

Then Frodo's heart flamed within him , and without thinking what he did, wheter it was folly or dispair or courage, he took the Phial in his left hand, and with his right hand drew his sword. Sting flashed out and the sharp elven-blade sparkled in the silver light, but at its edges a blue fire flicked. Then holding the star aloft and the bright sword advanced, Frodo, hobbit of the Shire walked steadily down to meet the eyes.

It strikes me that the Phial by itself didn't scare Shelob, nor even Frodo's call "Aiya Earendil Elenion ancalima!" It is only when Frodo gathers his own courage that it works!
Btw It took me a heck of a time to find out what "ancalima" means! Now I know more, and Davem's post about this is fascinating!
Apparently Sting shines blue also in Shelob's presence - not only that of orcs!

Frodo and Sam discover the true shape of Shelob only very late in the chapter.

In fact, Frodo never sees her at all, since she comes at him from behind. Later, in Cirith Ungol, he asks Sam: "Something hit me, didn't it?"

One thing that strikes me is the major shift that occurs during this chapter. It begins with "Gollum in front and the hobbits now side by side," but finishes with Sam running after him having "forgotten everything else but the red hot fury in his brain and the desire to kill Gollum." This simple shift between just these two paragraphs highlights the changes that almost all the separated characters are experiencing in their respective situations. Théoden has talked with Ghan-buri-Ghan and is preparing to ride to the Pelennor, Faramir's troops are retreating, and Aragorn is at Pelargir. The shift in Frodo and Sam's events is brought about by their characteristically distinct, but equally noteworthy, actions, which also ties in to that first paragraph.

It would be interesting to know, from anyone better-versed than me in older and classical literature, if before Tolkien the spider was a common element and symbol of writing for secrecy, evil, and dread. It certainly is now, and my question is if Shelob and Ungoliant helped to spurn the idea.

I also need to say that I love the idea that for most of their journey, Frodo and Sam's greatest fear and danger has been being seen, and here, where it at first seems to them that they will be able to finally be able to creep unnoticed through the dark, the monster appears in the form of "the dreadful stare of those baleful...monstrous and abominable eyes."
