Professor Tolkien was a great lover of nature: he was keenly aware of the flora around him, loved trees profoundly and respected them. Thus, trees and various plants appear in his books extensively, and are far from being in the background of events.
In Tolkien’s universe various notions can have special significance, which sometimes shows in small details and aspects. The concepts of light and darkness are deep and far-reaching: sometimes they are not a mere background for a story, but a very important player in the events of Middle-earth. In the present reflection I am going to look into the matter of sunlight and its influence on the dark powers of Middle-earth.
