Open, door! open, door!
And let me come in.

And the third time the door did open, and he went in, and it closed
with a click, and Childe Rowland was left in the dark.

It was not exactly dark, but a kind of twilight or gloaming. There
were neither windows nor candles, and he could not make out where the
twilight came from, if not through the walls and roof. These were
rough arches made of a transparent rock, incrusted with sheepsilver
and rock spar, and other bright stones. But though it was rock, the
air was quite warm, as it always is in Elfland. So he went through
this passage till at last he came to two wide and high folding-doors
which stood ajar. And when he opened them, there he saw a most
wonderful and glorious sight. A large and spacious hall, so large that
it seemed to be as long, and as broad, as the green hill itself. The
roof was supported by fine pillars, so large and lofty, that the
pillars of a cathedral were as nothing to them. They were all of gold
and silver, with fretted work, and between them and around them,
wreaths of flowers, composed of what do you think? Why, of diamonds
and emeralds, and all manner of precious stones. And the very key-
stones of the arches had for ornaments clusters of diamonds and
rubies, and pearls, and other precious stones. And all these arches
met in the middle of the roof, and just there, hung by a gold chain,
an immense lamp made out of one big pearl hollowed out and quite
transparent. And in the middle of this was a big, huge carbuncle,
which kept spinning round and round, and this was what gave light by
its rays to the whole hall, which seemed as if the setting sun was
shining on it.
