- Boss (architecture)
In architecture, a boss is a knob or protrusion of stone or wood.
One common example of a boss can be found in the
ceiling s of buildings, particularly at the intersection of a vault. InGothic architecture , such roof bosses (or ceiling bosses) were often intricately carved with foliage, heraldic devices or other decorations. Many feature animals, birds, or human figures or faces, sometimes realistic, but often grotesque: theGreen Man is a frequent subject.Bosses were also an important feature of ancient and Classical construction. When stone components were rough-cut offsite at quarries, they were usually left with bosses (small knobs) protruding on at least one side. This allowed for easy transport of the materials to the site; once there, the bosses also facilitated raising and/or inserting the pieces into place. An excellent and still extant example of such bosses can be seen at the Greek Doric temple of
Segesta , at which construction was never completed. The bosses of several key elements of the temple, notably thecrepidoma , remain as a testament to the construction process.Gallery
