The English fireplace was modified at the end of the seventeenth century, when coal began to replace wood. Chippendale gives many designs for beautiful basket-grates, such as were set in the large fireplaces originally intended for wood; for it was not until later that chimneys with smaller openings were specially constructed to receive the fixed grate and the hob-grate.

It was in England that the architectural treatment of the over-mantel was first abandoned. The use of a mirror framed in a panel over the fireplace had never become general in England, and toward the end of the eighteenth century the mantel-piece was frequently surmounted by a blank wall-space, on which a picture or a small round mirror was hung high above the shelf (see [Plate XLVII]). Examples are seen in Moreland's pictures, and in prints of simple eighteenth-century English interiors; but this treatment is seldom found in rooms of any architectural pretensions.

The early American fireplace was merely a cheap provincial copy of English models of the same period. The application of the word "Colonial" to pre-Revolutionary architecture and decoration has created a vague impression that there existed at that time an American architectural style. As a matter of fact, "Colonial" architecture is simply a modest copy of Georgian models; and "Colonial" mantel-pieces were either imported from England by those who could afford it, or were reproduced in wood from current English designs. Wooden mantels were, indeed, not unknown in England, where the use of a wooden architrave led to the practice of facing the fireplace with Dutch tiles; but wood was used, both in England and America, only from motives of cheapness, and the architrave was set back from the opening only because it was unsafe to put an inflammable material so near the fire.

After 1800 all the best American houses contained imported marble mantel-pieces. These usually consisted of an entablature resting on columns or caryatides, with a frieze in low relief representing some classic episode, or simply ornamented with bucranes and garlands. In the general decline of taste which marked the middle of the present century, these dignified and well-designed mantel-pieces were replaced by marble arches containing a fixed grate. The hideousness of this arched opening soon produced a distaste for marble mantels in the minds of a generation unacquainted with the early designs. This distaste led to a reaction in favor of wood, resulting in the displacement of the architrave and the facing of the space between architrave and opening with tiles, iron or marble.

People are beginning to see that the ugliness of the marble mantel-pieces of 1840-60 does not prove that wood is the more suitable material to employ. There is indeed something of unfitness in the use of an inflammable material surrounding a fireplace. Everything about the hearth should not only be, but look, fire-proof. The chief objection to wood is that its use necessitates the displacement of the architrave, thus leaving a flat intermediate space to be faced with some fire-proof material. This is an architectural fault. A door of which the architrave should be set back eighteen inches or more to admit of a facing of tiles or marble would be pronounced unarchitectural; and it is usually admitted that all classes of openings should be subject to the same general treatment.

Where the mantel-piece is of wood, the setting back of the architrave is a necessity; but, curiously enough, the practice has become so common in England and America that even where the mantel is made of marble or stone it is set back in the same way; so that it is unusual to see a modern fireplace in which the architrave defines the opening. In France, also, the use of an inner facing (called a retrécissement) has become common, probably because such a device makes it possible to use less fuel, while not disturbing the proportions of the mantel as related to the room.

The reaction from the bare stiff rooms of the first quarter of the present century—the era of mahogany and horsehair—resulted, some twenty years since, in a general craving for knick-knacks; and the latter soon spread from the tables to the mantel, especially in England and America, where the absence of the architectural over-mantel left a bare expanse of wall above the chimney-piece.

The use of the mantel as a bric-à-brac shelf led in time to the lengthening and widening of this shelf, and in consequence to the enlargement of the whole chimney-piece.

Mantels which in the eighteenth century would have been thought in scale with rooms of certain dimensions would now be considered too small and insignificant. The use of large mantel-pieces, besides throwing everything in the room out of scale, is a structural mistake, since the excessive projection of the mantel has a tendency to make the fire smoke; indeed, the proportions of the old mantels, far from being arbitrary, were based as much on practical as on artistic considerations. Moreover, the use of long, wide shelves has brought about the accumulation of superfluous knick-knacks, whereas a smaller mantel, if architecturally designed, would demand only its conventional garniture of clock and candlesticks.

The device of concealing an ugly mantel-piece by folds of drapery brings an inflammable substance so close to the fire that there is a suggestion of danger even where there is no actual risk. The lines of a mantel, however bad, represent some kind of solid architrave,—a more suitable setting for an architectural opening than flimsy festoons of brocade or plush. Any one who can afford to replace an ugly chimney-piece by one of good design will find that this change does more than any other to improve the appearance of a room. Where a badly designed mantel cannot be removed, the best plan is to leave it unfurbelowed, simply placing above it a mirror or panel to connect the lines of the opening with the cornice.
