What is the author's style in The Critic by Richard Brinsley Sheridan?

Almost all eighteenth-century plays featured prologues, recited on their opening nights by notable celebrities or writers and later reprinted in newspapers. As Mary E. Knapp points out in her 1961 study, Prologues and Epilogues of the Eighteenth Century, one purpose of the prologue was to "cajole the audience into a pleasant frame of mind so that they would be in a friendly mood before the curtain was drawn up." Another important function a prologue served was to point out the upcoming play's themes so that the audience could more readily identify them as the drama unfolded.
