Tom Bombadil or Treebeard!
read this:
Gandalf calls Tom Bombadil the eldest being in existence; this is also evidenced by his Sindarin name Iarwain Ben-adar (Eldest and Fatherless). Dwarves called him Forn (Scandinavian, meaning "Ancient" or "Belonging to the distant past"), Men Orald (compare to German: uralt, very old). All these names apparently mean "Eldest." Treebeard also calls himself the eldest living being of Middle-earth and says that he was there before anyone else. However, Tolkien remarked in another context: "Treebeard is a character in my story, not me; and though he has a great memory and some earthy wisdom, he is not one of the Wise, and there is quite a lot he does not know or understand."
and now this poem by Tom^^ enjoy^^
Now let the song begin! Let us sing together
Of sun, stars, moon and mist, rain and cloudy weather,
Light on the budding leaf, dew on the feather,
Wind on the open hill, bells on the heather,
Reeds by the shady pool, lilies on the water:
Old Tom Bombadil and the River-daughter!
Old Tom Bombadil is a merry fellow;
Bright blue his jacket is, and his boots are yellow.
green were his girdle and his breeches all of leather;
he wore in his tall hat a swan-wing feather.
He lived up under Hill, where the Withywindle
ran from a grassy well down into the dingle.
Hey! Come merry dol! derry dol! My darling!
Light goes the weather-wind and the feathered starling.
Down along under Hill, shining in the sunlight,
Waiting on the doorstep for the cold starlight,
There my pretty lady is, River-woman's daughter,
Slender as the willow-wand, clearer than the water.
Old Tom Bombadil water-lilies bringing
Comes hopping home again. Can you hear him singing?
Hey! Come merry dol! derry dol! and merry-o,
Goldberry, Goldberry, merry yellow berry-o!
Poor old Willow-man, you tuck your roots away!
Tom's in a hurry now. Evening will follow day.
Tom's going home home again water-lilies bringing.
Hey! come derry dol! Can you hear me singing?
Hop along, my little friends, up the Withywindle!
Tom's going on ahead candles for to kindle.
Down west sinks the Sun: soon you will be groping.
When the night-shadows fall, then the door will open,
Out of the window-panes light will twinkle yellow.
Fear no alder black! Heed no hoary willow!
Fear neither root nor bough! Tom goes on before you.
Hey now! merry dol! We'll be waiting for you!
