Hmm, I really didn't expect this thread to 'thrive' as it has. I can't say I'm dissapointed, though.
Estelyn, thanks for the link. I see the caretakers of that collection have also taken notice of
Olorin on Orthanc, (despite the fact that they seem to be calling it
Gandalf at Isengard, but it's the same principle).
Ah, abstraction, a bit of an oddity, but often does fanatical justice to many, harder-to-describe, scenes in the Tolkein compendium. One artiste who tried his hand at abstract art on Tolkein, despite being a normally realistic artist, was the antebellum painter and sketcher, Winslow Homer. He was one of the few artists who created a surplus of abstractorealistic art based around the Silmarillion.
Fountain and Fire: Ecthelion and Gothmog

This rather bizarre interpretation makes Ecthelion as a soldier, with his pointed helm very pointed indeed, while Gothmog, Lord of the Balrogs, Lieutenant of Angband, is depicted as no more than a man atop a bench with a club. This work has inspired much controversy because of its apparent abstraction.
Some magnificent finds we have here, and I hope that we as a community can delve further into the artistic culture spawned from Tolkein. Much gratitude for all the accolades, since I do not deserve them. This is merely a topic waiting to be made, and I put the pen to paper as it were, or the digits to keys at least. *bows thankfully*
