Fireplace in a home library

An excellent image of a home library fireplace (Riccardo Cuppini). From the looks of it, the library does not have any books that are intrinsically valuable (which is perfectly ok). Otherwise it would be a risky idea to have a fireplace in a library room. You can see all the black surrounding the hearth! Still, the fireplace is massive with the fire burning deep within the structure. The wide mantel collects a lot of the soot and the heat is projected away from the books. Another amazing thing is that the fireplace looks very much used. There are various utensils that indicate that sometimes it is even used for cooking.
