I love thinking on verse/image matches. I don't know about the rest of you, but it seems to me there is no consistent methodology to Byron's process in this area. However, I do think the connections are intended to be made. (heck Roanoke Island all but confirms it)
Let's look at Houston.
Our [partial] Pierre quote gets us to Hermann Park. That's excellent alone, but what if this line was intended to build the whole puzzle? Maybe give us an image to use too?
What I and many have found interesting is that if we "go through a dictionary of quotations," the quote he's referencing goes on:
Seems this tower of delight could be caused by something as simple as watching a leaf. People have taken this to mean we're looking for another tree. Perhaps... [yawn]
Byron has amended this quote himself by saying our "[tower of delight] falls softly in December night." Hm... We can feel confident he intended for us to realize that the delight in question is a leaf because he preserved the verb "fall" from the original quote. Leaves certainly fall softly.
So this leaf falls at night?
Any images with a bunch of leaves? Maybe an overt night sky? Just one you say? And we already think it goes with this verse? Interesting...
(heck... maybe that night sky has a cross constellation in it that can only be seen from Texas and Florida?)
