cupola

1. a roof or ceiling in the form of a dome

2. a small structure, usually domed, on the top of a roof or dome

3. a vertical air-blown coke-fired cylindrical furnace in which iron is remelted for casting

Cupola

A tower-like device rising from the roof, usually terminating in a miniature dome or turret with a lantern or windows to let light in.

cupola

[′kyü·pə·lə]

(geology)

An isolated, upward-projecting body of plutonic rock that lies near a larger body; both bodies are presumed to unite at depth.

(metallurgy)

A vertical cylindrical furnace for melting gray iron for foundry use; the metal, coke, and flux are put into the top of the furnace onto a bed of coke through which air is blown. Also known as furnace cupola.

Cupola

a decorative crowning piece on church buildings, which in Russian architecture has the shape of a helmet, an onion, a pear, or a similar object.

The cupola rests on a round or faceted drum; originally (in stone buildings) it was the external part of the domed top of the drum. The cupola lends to the upper part of the building its characteristic silhouette and picturesqueness, which is enhanced by the cupola’s gilding, coloring, pattern, and material covering (such as tile, lemekh —plowshare-shaped wooden tile—or wrought iron). Cupolas are also found in the architecture of the Caucasus (conical and umbellate cupolas), Middle Asia, India, and some European countries.
