There is a charm upon [this poem] which can only be felt in silent submission of wonder". Even John Livingston Lowes -- culpable, if ever anyone has been, of murdering to dissect -- insisted on the elusive magic of Coleridge's dream vision: "For Kubla Khan is as near enchantment, I suppose, as we are like to come in this dull world." While one may track or attempt to track individual images to their sources, Kubla Khan as a whole remains utterly inexplicable -- a "dissolving phantasmagoria" of highly charged images whose streaming pagent is, in the final analysis, "as aimless as it is magnificent". The earth has bubbles as the water has, and this is of them.

Yet despite this decisive shift in the critical temper, there remain some influential voices to argue for the mystery of Kubla Khan.
