Up to the twelfth century, fires were simply made in the middle of a home by a
hypocaust, or with
braziers, or by fires on the
hearth with smoke vented out through the
lantern in the roof. As time went on, the placement of fireplaces moved to the wall, incorporating
chimneys to vent the
smoke. This permitted the design of a very elaborate, rich, architectural focal point for a grand room. At a later date, in consequence of the greater width of the fireplace, flat or segmental arches were thrown across and constructed with
archivolt, sometimes
joggled, with the thrust of the arch being resisted by bars of iron at the back. In domestic work of the fourteenth century, the chimneypiece was greatly increased in order to allow of the members of the family sitting on either side of the fire on the hearth, and in these cases great beams of
timber were employed to carry the hood; in such cases the fireplace was so deeply recessed as to become externally an important architectural feature, as at
Haddon Hall. The largest chimneypiece existing is in the great hall of the
Palais des Comtes at
Poitiers, which is nearly wide, having two intermediate supports to carry the hood; the stone
flues are carried up between the
tracery of an immense window above. The history of carved mantels is a fundamental element in the history of Western art. Every element of European sculpture can be seen on great mantels. Many of the historically noted sculptors of the past, i.e.,
Augustus St. Gaudens, designed and carved magnificent mantels, some of which can be found on display in the world's great museums. Exactly as the facade of a building is distinguished by its design, proportion, and detail so it is with fine mantels. The attention to carved detail is what defines a great mantel.
Today Up until the 20th century and the invention of mechanized contained heating systems, rooms were heated by an open or central fire. A modern fireplace usually serves as an element to enhance the grandeur of an interior space rather than as a heat source. Today, fireplaces of varying quality, materials and style are available worldwide. The fireplace mantels of today often incorporate the architecture of two or more periods or cultures. ==Styles==
