George Eric Mackay, Once a Week (1863)
“ Query, why is the villain of the piece always a baritone? Perhaps it is this sameness of material that in some measure detracts from the merit of the libretto. It is always excessively amusing—even in the most serious operas—to see that jealous, wilful, mal-à-propos sort of suitor, the baritone, always coming between the two innammorati. The tenor loathes him (in not a few of the operas) , but somehow or other, like the hero of “Waverley,” he is always more famous for manners than for manliness. ”
