And here is another example:
"'As you wish,' Vagnhofdi sighed, like a wind through tall pines.'"
-Poul Anderson, War Of The Gods (Ballantine Books, New York, 1999), p. 38.
Vagnhofdi is giant three times higher than a tall man, like a pine, and his sigh is like the sound of wind through tall pines. Where you and I see a pine and hear the wind, maybe a pagan sees a giant and hears his voice?
