The _Don Juan_ indeed has great power; but its power is owing to the force of the serious writing, and to the oddity of the contrast between that and the flashy passages with which it is interlarded. From the sublime to the ridiculous there is but one step. You laugh and are surprised that any one should turn round and _travestie_ himself: the drollery is in the utter discontinuity of ideas and feelings. He makes virtue serve as a foil to vice; _dandyism_ is (for want of any other) a variety of genius. A classical intoxication is followed by the splashing of soda-water, by frothy effusions of ordinary bile. After the lightning and the hurricane, we are introduced to the interior of the cabin and the contents of wash-hand basins. The solemn hero of tragedy plays _Scrub_ in the farce. This is ‘very tolerable and not to be endured.’ The Noble Lord is almost the only writer who has prostituted his talents in this way. He hallows in order to desecrate; takes a pleasure in defacing the images of beauty his hands have wrought; and raises our hopes and our belief in goodness to Heaven only to dash them to the earth again, and break them in pieces the more effectually from the very height they have fallen. Our enthusiasm for genius or virtue is thus turned into a jest by the very person who has kindled it, and who thus fatally quenches the sparks of both. It is not that Lord Byron is sometimes serious and sometimes trifling, sometimes profligate, and sometimes moral—but when he is most serious and most moral, he is only preparing to mortify the unsuspecting reader by putting a pitiful _hoax_ upon him. This is a most unaccountable anomaly. It is as if the eagle were to build its eyry in a common sewer, or the owl were seen soaring to the mid-day sun. Such a sight might make one laugh, but one would not wish or expect it to occur more than once.[51]
