I am persuaded there is no triumph equal to one achieved on the stage—it comes so immediate and so home : you have before you the mass of human beings whose sympathies are at your will; you witness the emotions which you raise, you see the tears which you command : the poet has erected the statue, but it is for you to give it life—the words must find their music on your lips—the generous sentiment, the exalted hope, the touches of deep feeling, ask their expression from you : surely such influence is among the triumphs of the mind, ay and a great and noble triumph.

Heath's book of Beauty, 1833 (1832)
