Such a chimney piece is to be seen in the parlor at Cliveden, its fireplace opening partly closed up to convert it for use with the coal grate shown by the accompanying illustration. In this instance the carved consoles support the shelf rather than the panel of the overmantel, which engages neither the shelf nor the cornice with its prominent double denticulated molding. Otherwise, the chimney piece is essentially the same in arrangement as that in the parlor at Mount Pleasant. It has the same pleasing breadth and generally good proportions, but is severely simple in detail, the conventional ovolo of egg and dart motive without the astragal which outlines the black marble fireplace facings being the only enriched molding. As was customary, the shelf takes the form of a cymatium, and the projections above the consoles and central panel are characteristic details. Much like this, though simpler in the absence of any enriched moldings and having less projection, is the chimney piece on the second floor of an old Spruce Street house shown by an accompanying illustration. It has substantially the same overmantel frame and mantel treatment. Incidentally it furnishes an excellent example of the complete paneling of one end of a room with the familiar six-panel ordinary inside doors each side of the fireplace. The architrave casings of the doors with their horizontal projections over the lintel are in pleasing accord with the corresponding projections of the overmantel frame and of the facing of the fireplace opening. Toward the end of the eighteenth century and for some years thereafter, mantels with a shelf, but without any overmantel treatment of the chimney breast, became the rule. The whole construction was usually projected from twelve to eighteen inches into the room, however, and as the surbase and skirting or a paneled wainscot and the cornice above was carried around it, the effect was much like that of a chimney piece, especially when a large, ornamental framed mantel mirror occupied the space over the chimney breast. The mantel itself took the form of a complete entablature above the fireplace opening, supported by pilasters at each side, the pilasters usually being carried up through the entablature by projections in architrave, frieze and cornice respectively, and the cymatium of the cornice forming the mantel shelf. The classic orders supplied much of the ornamental detail with which these mantels were embellished, and the work gave full scope to the genius of English and American wood-carvers, of whom there were many of marked ability in America.
