I recently read that the description of the Golden Hall I am familiar with might be incomplete.
In The Lord of the Rings: The Two Towers, Book Three, Chapter 6, "the King of the Golden Hall" there are descriptions of Edoras, the village where the King of Rohan resides, and of Meduseld, the Golden Hall which is his residence.
Legolas looked at Edoras from a distance and described it to his companions:
...Within there rise the roofs of houses; and in the midst, set upon a green terrace, there stands a lofty hall of men. And it seems to my eyes that it is thatched with gold. The light of it shines far over the land. Golden, too, are the posts of its doors...
I don't know if the thatched roof is supposed to be golden colored straw or actual gold. Straw thatching is millions of times more common, but some real buildings have had golden or gilded roofs and domes.
When they enter the hall:
...The hall was long and wide and filled with shadows and half lights; mighty pillars upheld its lofty roof. But here and there bright sunbeams fell in glimmering shafts from the eastern windows high under the deep eaves. Through the louvre in the roof, above the thin wisps of issuing smoke, the sky showed pale and blue. As their eyes changed, the travelers perceived that the floor was paved with stones of many hues, branching runes and strange devices intertwined beneath their feet. They saw now that the pillars were richly carved, gleaming dully with gold and half-seen colours. Many woven cloths were hung upon the walls, and over their wide spaces marched figures of ancient legend, some dim with years, some darkl-7ing in the shade. But upon one form the sunlight fell: a young man upon a white horse. He was blowing a great horn, and his yellow hair was flying in the wind. The horse's head was lifted, and its nostrils were wide and red as it neighed, smelling battle afar. Foaming water, green and white, rushed and curled about its knees.
'Behold Eorl the Young!' Said Aragorn. 'Thus he rode out of the North to the Battle of the Field of Celebrant.'
Now the four companions went forward, past the clear wood-fire burning upon the long heath in the midst of the hall. Then they halted. At the far end of the house, beyond the heath and facing north toward the doors, was a dais with three steps; and in the middle of the dais was a great gilded chair.
And I think that there are later mentions of other rooms within the building or in buildings attached to or near to the hall.
These quotes are from my 1966 Ballantine Books copy.
Has a comment with a link to an article:
This paper was first read at the launch of the celebration of the 50th anniversary of the first appearance of The Lord of the Rings, organized by the Società Tolkieniana Italiana at European Parliament, Rome, on Monday 19th January.
So it should date to about 2004 or 2005.
On page 5 it says:
Through the last ten years, corrections have continued, most notably the discover that several lines had disappeared from the description of Theoden's hall. As an archaeologist, I had been puzzled by the description as I read it, since it seemed to depart somewhat from the excavated remains on which it was clearly based.
Any edition of The Two Towers that included the missing lines mentioned would have been published in or after 1994/95, and thus decades after my copy.
So what are those extra lines and how do they change the description of Meduseld? Can anyone quote them?
