In Victorian theatre, "degrade high and beautiful themes ... had been the regular proceeding in burlesque, and the age almost expected it" However, Gilbert's burlesques were considered unusually tasteful compared to the others on the London stage. Isaac Goldberg wrote that these pieces "reveal how a playwright may begin by making burlesque of opera and end by making opera of burlesque." Gilbert would depart even further from the burlesque style from about 1869 with plays containing original plots and fewer puns. His first full-length prose comedy was "An Old Score" (1869).
