The plays of the Roman dramatist were deliberately adapted from the Greek, and they therefore had an avowedly literary source, whereas the immediate origin of the plays performed in New York was only an unpretending sketch for a variety-show; but both of these groups had the same flavor of veracity in their reproduction of the teeming life of the tenements. Humble as is the beginning of the 'Mulligan Guard' series, at least as humble is the beginning of the improvised pieces of the Italians, the comedy of masks, which Molière lifted into literature in his 'Etourdi,' and in his 'Fourberies de Scapin.' In the hands of the Italians the comedy of masks was absolutely unliterary, since it was not even written, and its performers were not only comedians, but acrobats also. And here the drama is seen to be impinging on the special sphere of the circus--just as it does again in the plays prepared for the New York Hippodrome. It is more than probable that this improvised comedy of the Italians is the long development of a primitive semi-gymnastic, semi-dramatic entertainment, given by a little group of strollers, performing in the open market-place to please the casual crowd that might collect. Equally unpretending was the origin of the French melodrama, which Victor Hugo lifted into literature in his 'Hernani' and 'Ruy Blas.' It began in the temporary theaters erected for a brief season in one or the other of the fairs held annually in different parts of Paris. The performances in these playhouses were almost exactly equivalent to those in our variety-shows; they were medleys of song and dance, of acrobatic feats and of exhibitions of trained animals. As in our own variety-shows, again, there were also little plays performed from time to time, at first scarcely more than a framework on which to hang songs and dances, but at last taking on a solider substance, until finally they stiffened themselves into pathetic pieces in three or more acts, capable of providing pleasure for a whole evening. The humor was direct, and the characters were painted in the primary colors; the passions were violent, and the plots were arbitrary; but the playwrights had discovered how to hold the interest of their simple-minded spectators, and how to draw tears and laughter at will.
