[Vathek] has, in parts, been called, but to some judgments, never is, dull: it is certainly in parts, grotesque, extravagant and even nasty. But Beckford could plead sufficient "local colour" for it, and a contrast, again almost Shakespearean, between the flickering farce atrocities of the beginning and the sombre magnificence of the end. Beckford's claims, in fact, rest on the half-score or even half-dozen pages towards the end: but these pages are hard to parallel in the later literature of prose fiction.
