"The hackneyed voluptuary is like the jaded epicure, the mere
listlessness of whose appetite becomes at length a sufficient penalty
for having made it the principle object of his enjoyment and
cultivation." -- Sir Walter Scott, 'Peveril of the Peak'
Voluptuary derives from Latin voluptarius, "devoted to pleasure," from
voluptas, "pleasure."
