The invention of the box-set, of a room with walls and ceilings, doors and windows, led inevitably to the appropriate furnishing of this room with tangible tables and chairs. Even in the eighteenth century the stage had been very empty; it was adorned only with the furniture actually demanded by the action of the drama; and the rest of the furniture, bookcases and sideboards, chairs and tables, was frankly painted on the wings and on the back-drop by the side of the painted mantelpieces, the painted windows, and the painted doors. In the plays of the twentieth century characters sit down and change from seat to seat; but in the plays produced in England and in France before the first quarter of the nineteenth century all the actors stood all the time--or at least they were allowed to sit only under the stress of dramatic necessity--as in the fourth act of 'Tartuffe,' for instance. In all of Molière's comedies there are scarcely half a dozen characters who have occasion to sit down; and this sitting-down is limited to three or four of his more than thirty pieces. Nowadays every effort is made to capture the external realities of life. Sardou was not more careful in composing his stage-sittings in his fashion than was Ibsen in prescribing the scenic environment that he needed. The author's minute descriptions of the scenes where the action of the 'Doll's House' and of 'Ghosts' passes prove that Ibsen had visualized sharply the precise interior which was, in his mind, the only possible home for the creatures of his imagination. And Mr. Belasco has recently bestowed upon the winning personality of his 'Peter Grimm' the exact habitation to which that appealing creature would return in his desire to undo after death what in life he had rashly commanded.
