Brian Stableford's introduction is valuable here, in which he compares "Coins de Byzance" (the major part of this multi-part work) to the Jean Lorrain's generally accepted masterpiece, Monsieur de Phocas, to which it might be called a companion-piece, by stating "it is clearly subject to to the pressure of melodramatic inflation, forced to outreach its predecessor in its bizarrerie," and, perhaps by virtue of that, the character of Wladamir, a "caricaturish monster" becomes "possessed of a fascinating moral and artistic complexity."
Indeed, and while I am tempted to quote from a particular Christ-like passage as an example, I will just say Wladamir's archetypical ennui and excess of the Decadents becomes unique under this inflation, and the Salaambo-meets-Satyricon calvalcade of his "court" just furthers this. The earlier, non-Byzance pieces, set the stage for a Poe-esque narrative of fin de siecle Nice absurdity, one that I can't help but think of Prince's Under the Cherry Moon, another blindingly decadent portrait set on the French Riviera, in a fin de siecle of it's own century.
