When they caught his words again they found that he had now wandered into strange regions beyond their memory and beyond their waking thought, into times when the world was wider, and the seas flowed straight to the western Shore; and still on and back Tom went singing out into ancient starlight, when only the Elf-sires were awake. Then suddenly he stopped, and they saw that he nodded as if he was falling asleep. The hobbits sat still before him, enchanted; and it seemed as if, under the spell of his words, the wind had gone, and the clouds had dried up, and the day had been withdrawn, and darkness had come from East and West, and all the sky was filled with the light of white stars.

Whether the morning and evening of one day or of many days had passed Frodo could not tell. He did not feel either hungry or tired, only filled with wonder. The stars shone through the window and the silence of the heavens seemed to be round him. He spoke at last out of his wonder and a sudden fear of that silence:

‘Who are you, Master?’ he asked.

'Eh, what?’ said Tom sitting up, and his eyes glinting in the gloom. 'Don’t you know my name yet? That’s the only answer. Tell me, who are you, alone, yourself and nameless? But you are young and I am old. 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 Outside.’
