How would you explain this sentence? The first few doors the tired led only to spare bedrooms, but soon they came to a very long room full of pictures and there they found a suit of armor; after that was a room all hung with green, with a harp in one corner; and then came three steps down and five steps up… How would you explain this sentence: after that was a room all hung with green? How would you explain “after that”? There was a room at the back of the previous room? Or they just went out of the previous room and entered another room? By the way, what does “hung with green” mean in the same sentence? Thanks!
