I intended to add that the real problem with the article I cited is not so
much that the author mistook Sauron's Eye for his whole being - better
scholars have made dumber errors than that without Jackson's help - but
that the whole image comes straight from Jackson without the author
apparently realizing it.
The quote, again, is, "In his DISEMBODIED state, Sauron is REDUCED to a
single, large, unblinking eye," and I've capitalized the words that
emphasize the diminishment of this view of the character, the physical
helplessness of Jackson's Sauron, something that would surely not be the
first thing that occurs to someone who thinks of the Eye of Sauron only in
terms of the the very active, aggressive Eye that the characters feel
searching for them - something that Jackson tends to depict just in the
form of sudden flash cuts to something that looks less like an eye than
like a body part not usually mentioned in polite company.
Also note the word "large". The size of the Eye is not really at issue in
Tolkien; only when you see Jackson does the immensity, and the equally
immense absurdity, of it really strike.
If Sauron The Disembodied Eyeball ever got the Ring back, how would he wear it?
