At first the beauty of the melodies and of the interwoven words in elven-tongues, even though he understood them little, held him in a spell, as soon as as he began to attend to them. Almost it seemed that the words took shape, and visions of far lands and bright things that he had never yet imagined opened out before him; and the firelit hall became like a golden mist above the seas of foam that sighed upon the margins of the world. Then the enchantment became more and more dreamlike, until he felt that an endless river of swelling gold and silver was flowing over him, too multitudinous for its pattern to be comprehended; it became part of the throbbing air about him, and it drenched and drowned him. swiftly he sank under its shining weight into a deep realm of sleep.
