Diderot had perceived very early that the complacency with which his countrymen regarded the national theatre was extravagant. He would not allow a comparison between the conventional classic of the French stage and the works of the Greek stage. He insisted in the case of the Greeks that their subjects are noble, well chosen, and interesting; that the action seems to develop itself spontaneously; that their dialogue is simple and very close to what is natural; that the denouements are not forced; that the interest is not divided nor the action overloaded with episodes. In the French classic he found none of these merits. He found none of that truth which is the only secret of pleasing and touching us; none of that simple and natural movement which is the only path to perfect and unbroken illusion. The dialogue is all emphasis, wit, glitter; all a thousand leagues away from nature. Instead of artificially giving to their characters _esprit_ at every point, poets ought to place them in such situations as will give it to them. Where in the world did men and women ever speak as we declaim? Why should princes and kings walk differently from any man who walks well? Did they then gesticulate like raving madmen? Do princesses when they speak utter sharp hissings? People believe us to have brought tragedy to a high degree of perfection. It is not so. Of all kinds of literature it is the most imperfect.[283] The ideas which appeared thus incongruously in the tales of 1748 reappeared in the direct essays on the drama in 1757 and 1758. We have left nothing undone, he said, to corrupt dramatic style. We have preserved from the ancients that emphasis of versification which was so well fitted to languages of strong quantity and marked accent, to vast theatres, to a declamation that had an instrumental accompaniment; and then we have given up simplicity of plot and dialogue, and all truth of situation.[284] La Motte nearly fifty years before had attacked the pseudo-classic drama. He had inveighed against the unities, against long monologues, against the device of confidants, and against verse. His assault, in which he had the powerful aid of Fontenelle, was part of that battle between Moderns and Ancients with which the literary activity of the century had opened. The brilliant success of the tragedies of Voltaire had restored the lustre of the conventional drama, though Voltaire infused an element of the romantic under the severity of the old forms. But the drama had become even less like Sophocles and Euripides in _Zaire_ than in _Phedre_ or _Iphigenie_. Voltaire intended to constitute the French drama into an independent form. He expected to be told that he was not like Sophocles, and he did not abstain from some singularly free railing against Euripides. The Greek pieces often smacked too much of the tone of the fair to satisfy him; they were too familiar and colloquial for a taste that had been made fastidious by the court-pieces of Lewis XIV.
