I ditch my theory of 'It didnt affect him cuz he doesnt care'. Ive thought of something better...
He is a
Maia because:
a) Doesnt dissapear when
the Ring is put on
- The Ring grants power according to the stature of the bearer... Turning invisible, is a side-effect for those of lesser stature, seing as how
Men, and
Hobbits (those are examples of beings of lesser stature) turn invisible. If
Tom were to turn invisible, wich he didnt, that would mean he's of greater stature. Being a spirit of some sort.
b) What else could he be?
- Man; no. Look above for reason!
Hobbit; Highly doubt it
Elf; No. Look below
Dwarf; Highly doubt it
Vala; Probly not, seing as how the Vala removed themselves from ME, and if he was
Ulmo he would be more in touch with the water.
c) ''He is" ~
Goldberry
- 'Eldest, that's what I am. Mark my words, my friends: Tom was here before the river and the
trees; Tom remembers the first raindrop and the first acorn. He made paths before the Big People, and saw the little People arriving. He was here before the
Kings and the graves and the
Barrow-wights. When the
Elves passed westward, Tom was here already, before the seas were bent. He knew the dark under the stars when it was fearless--before the
Dark Lord came from the Outside'
~
Tom Bombadil
Those three points rule out Elves, men, Hobbits, and
Dwarves. Maia, Vala, and 'Ea' are the only choices left, and I highly doubt Tom being a Vala, seeing as how Goldberry is obviously of the same '
race' of Tom, if tat is a fair classification, and no two Vala would both dwell in a very small forrest of ME.
I highly doubt the Ea theory too, because if Tom was Ea itself, he would have more control than just inside
the Old Forrest. And
Tolkien would have reffered to him more and written more on him, because why would Tolkien leave out the Spirit of the World in his writings? Also, there are many Maia that were never written about, or had any descriptions of what they were. Tom Bombadil could be one of these many Maia.
My vote:
Maia
If Tom is some sort of classification, and i use that term loosely, he would most likely be Maia IMO. Or you can go with my Enigma idea, and have Tom just be. Just simply be there...
