"That sunny dome! Those caves of ice!" (47)
This recurring image cements the contrast between what man makes and what nature creates. By describing the dome as sunny and warm and the caves as cold and icy, Coleridge finds yet another way emphasize the difference between man and nature. But here, we see a harmonious juxtaposition of man and nature: the combined effect seems to delight our speaker. Nature and man work together to make a beautiful study in contrasts.
