In architectural detail the fireplace and overmantel recall that of the Whitby Hall chimney piece. There are similar black marble facings about the fireplace opening outlined by a hand-tooled molding, and similar elaborately carved consoles[175] supporting a handsomely molded panel with projecting ornamental corners, but in this instance the panel is surmounted by a highly ornamental top, consisting of a swag or broken pediment with an exquisitely hand-carved floreated design in high relief between the volutes which imparts a charming lightness and grace to the ensemble. Pilaster projections bearing nicely delineated leaf ornaments above the corners of the overmantel panel tie into corresponding projections in the cornice and unify the whole construction. Otherwise the chimney piece differs from that of Whitby Hall chiefly in its moldings, in which the Lesbian leaf is prominent. The ovolo about the marble facings of the fireplace bears the conventional bead and reel and egg and dart motives, the latter having a leaf design in alternation with the egg. The ogee molding outlining the overmantel panel is enriched with a larger and a smaller leaf motive in alternation, while the torus of the inner molding of this panel bears a little conventionalized flower in alternation with crossed flat fillets.
Altogether more pleasing is the chimney piece in the parlor at Mount Pleasant. In fact, it is regarded as one of the handsomest chimney pieces without a mantel shelf in America. Its excellence is due not to superiority of detail, but to better proportion, the breadth of the chimney breast being sufficient to make the overmantel panel practically square. This[176] great fireplace construction for burning four-foot logs projects into the room some eighteen inches, with wood-paneled sides, the adjoining walls being plastered. Around it are carried the chaste Ionic cornice with its prominent dentil course; and the paneled wainscot below corresponds to the pedestal of the order. In the general arrangement of the design, this chimney piece follows closely that of the one above, except that top, sides and bottom of the overmantel panel frame are alike. As at Whitby Hall the familiar Grecian fret very acceptably occupies the space between the inner and outer moldings of this frame and obviates the need of any elaborate carved decoration above the panel. Contrasting pleasingly with this fret and on opposite sides of it are a plain molded ovolo outlining the panel and a small floreated torus supplemented by a molded cymatium within. The pilaster projections tying the panel treatment to the cornice bear three nicely tooled vertical flower designs in a row, an unusual conception. An ovolo of conventional egg and dart motive with the customary bead and reel astragal outlines the black marble facings of the fireplace opening. The console ornamentation is strongly reminiscent of that at Whitby Hall.
The mantel shelf proper was far too practical and attractive a feature of the fireplace to be long abandoned, however. It furnished a convenient place for clocks, candlesticks, china and other ornaments,[177] and it appealed to the eye because of the homelike, livable appearance these articles of decoration gave to the room. About the middle of the eighteenth century the shelf of former times was reinstated and the overmantel was developed into a single large and elaborately framed panel over the chimney breast in which often hung a family portrait, a gilt-framed mirror or girandole.
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[178] 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.
