Hobbit Metaphors

At the OneRingNet:

nine visual metaphors in the Hobbit: including:
Blind mice and lesser lives.From the cat to the mouse. We have something of a double metaphor here: Beorn uses the word “blind” just as we see the mouse (as in “Blind Mice”); then picks up the mouse when he says that Dwarves are blind to those whose lives they deem “lesser than their own”.

And the lake will shine and burn.As Bard speaks this line from the prophecy, we see the sunlight shining on the lake, making it look on fire.
