An antique fireback in an antique fireplace is a beautiful combination. When we buy old fireplaces in French, we often get the original fireback with it. Firebacks were a luxury item in the old days, mainly used by royal families. Most of these antique fireback show the family weapon or a biblical story in the cast iron. A commonly seen weapon is the "Armes de France", with the French lily.
Later, these firebacks got a decorative image like scenery or classic stories on it. The firebacks also have a practical function: the cast iron absorbed the heat of the fire and radiated this into the room.
