Voltaire, though he adhered, in part at least, to the old subjects in his tragedies, is far more various and discursive in his mode of treating them. The prodigious fecundity of the author of a hundred volumes, the varied acquisitions of the philosopher, the historian, the satirist, the moralist, give diversity to his subjects, and an endless variety to his ideas. He possessed, as it were, a polyglot mind; he threw himself into the feelings and passions of every country and every age, and brought out in his dramas part at least of the inexhaustible store of human thoughts and events which have from the beginning of time agitated the human race. The East, with its sultans, its harems, its sultanas, and its jealousies, strongly arrested his imagination, and furnished the subjects of some of his finest pieces; witness _Mahomet_, _Bajazet_, _Tamerlane_, and _Zaire_. For this reason his tragedies are more general favourites now than either those of Corneille or Racine; you will see the audience in the parterre of the Theatre Francais repeating whole speeches from _Brutus_, _Alzire_, or _Le Fanatisme_, after the performer on the stage. They have sunk deeper into the general mind than any of their predecessors; more of their lines have become household expressions, as is the case with Shakspeare, Gray, and Campbell in England, than those of any other author in the French language. Voltaire, too, was strongly impressed with the necessity of keeping up the interest of his piece from first to last; he drives on the story with an untiring hand, and even before the final catastrophe, contrives to produce a passing excitement at every step, by subordinate and yet important events. What he constantly complains of in his admirable commentaries on Corneille is, that, in his inferior pieces at least, that great master lets the story flag, the interest die away, and that, trusting to the fascination of his language, the power of his thoughts, he neglects the important matters of dramatic power and stage effect. His perfect knowledge of both these important auxiliaries of his art, is not the least of Voltaire's many excellences; and has secured for him, to all appearance permanently, if not the first, unquestionably the most popular place in the French theatre. But still his dramas do not represent nature. They are noble pieces of rhetoric put into rhyme. They are the ablest possible debate arrayed in the pomp of Alexandrine verse. But they do not touch the heart like a few words in Sophocles, Euripides, or Shakspeare.
