The mind that thought of light, heavy, grey, yellow, still, swift, also conceived of magic that would make heavy things light and able to fly, turn grey lead into yellow gold, and the still rock into a swift water. If it could do the one, it could do the other; it inevitably did both. When we can take green from grass, blue from heaven, and red from blood, we have already an enchanter's power.
J. R. R. TolkienAnd when [Bรซor] lay dead, of no wound or grief, but stricken by age, the Eldar saw for the first time the swift waning of the life of Men, and the death of weariness which they knew not in themselves; and they grieved greatly for the loss of their friends. But Bรซor at the last had relinquished his life willingly and passed in peace; and the Eldar wondered much at the strange fate of Men, for in all their lore there was no account of it, and its end was hidden from them.
