Illuin: Lamp of the Valar is an attempt to portray one of the more beautiful images Tolkien describes in his intriguing accounts of Middle-earth’s prehistory. While I doubt that Yvanna’s giant trees would actually have surrounded the lamp Illuin, it is an artist’s prerogative sometimes to compose a picture which combines two interesting concepts as a “taste” of his ideas.
“And since, when the fires were subdued or buried beneath the primeval hills, there was need of light, Aulë at the prayer of Yvanna wrought two mighty lamps for the lighting of the Middle-earth… and the light of the Lamps of the Valar flowed out over the Earth, so that all was lit as it were in a changeless day.”
