In the book Angel and Demons, Dan Brown says under chapter 3:
The camber was dark. Medieval. Stone.
To me it looks like a very telegraphic kind of describing a space, which is very different than some older styles of writing where they describe a place in as much as a paragraph! Now, I'm thinking that since "dark" is an adjective, he could use those 2 other subsequent words as adjectives too, and wrote:
The chamber was dark, medieval, stony.
And it would have made more sense to me as a non-native speaker. I'm also thinking why it is better to write like he'd written, mixing noun and adjective forms. Is it ok in writing, to shorten as much as he had done ? and say "Stone." instead of saying "the chamber was made of stone."
