Fireplace mantel or mantelpiece, also known as a chimneypiece, originated in medieval times as a hood that projected over a grate to catch the smoke. The term has evolved to include the decorative framework around the fireplace, and can include elaborate designs extending to the ceiling. Mantelpiece is now the general term for the jambs, mantel shelf, and external accessories of a fireplace. For many centuries, the chimneypiece was the most ornamental and most artistic feature of a room, but as fireplaces have become smaller, and modern methods of heating have been introduced, its artistic as well as its practical significance has lessened.
In the early Renaissance style, the chimneypiece of the Palais de Justice at Bruges is a magnificent example; the upper portion, carved in oak, extends the whole width of the room, with nearly life-size statues of Charles V and others of the royal family of Spain. The most prolific modern designer of chimneypieces was G. B. Piranesi, who in 1765 published a large series, on which at a later date the Empire style in France was based. In France, the finest work of the early Renaissance period is to be found in the chimneypieces, which are of infinite variety of design.
The English chimneypieces of the early seventeenth century, when the purer Italian style was introduced by Inigo Jones, were extremely simple in design, sometimes consisting only of the ordinary mantel piece, with classic architraves and shelf, the upper part of the chimney breast being paneled like the rest of the room. In the latter part of the century the classic architrave was abandoned in favor of a much bolder and more effective molding, as in the chimneypieces at Hampton Court, and the shelf was omitted.
