Two major symbols in The Lord of the Rings deal with the theme of vision:
- Sauron's incarnation is an all-seeing eye
- Sauron's ring of power grants its user the ability to become invisible
What could be the significance of the duality between being always seen (by Sauron's eye) vs. disappearing from sight (by wearing the ring)? What might Tolkien have been trying to say using this theme, especially as it relates to all the other themes in the books, namely death, loss, etc.?
