The walls and ceiling of the fine Romanesque interior are covered with frescoes of 1570, subdued in colour and well suited to the character of the building; those of the octagonal cupola representing the Assumption of the Virgin are by Correggio, but much restored.

The duties of the other viziers were limited to attending the divan; they were called kubbe or cupola viziers from the fact that the council met under a cupola; they were pashas with three horse-tails, and were attended by large retinues, having generally achieved distinction as beylerbeys.

His principal architect was Domenico Fontana, who, in conjunction with Guglielmo della Porta, completed the uniquely beautiful cupola of St Peter's which had already been designed by Michelangelo in a detailed model.
In the very earliest submarines a cupola was built on the top of the hull, which was kept just above the surface when it was desired to take observations.
An optical tube replaced this cupola in the "Gustave Zede," and comprised a short tube (on top of the submarine) with a lens to close the top end, which was kept just above the surface when running submerged.
With a glass cupola; it is roofed with glass throughout, and is 320 yds.
Grey iron castings are made by remelting the pig iron either in a small shaft of " cupola " furnace, or in a reverberatory or " air " furnace, with very little change of chemical composition, and then casting it directly into suitable moulds, usually of either " baked," i.e.
Should several furnaces simultaneously make iron too rich in silicon, this may be diluted by pouring into the mixer some low-silicon iron melted for this purpose in a cupola furnace.
The melting can be done much more cheaply in a cupola or open-hearth furnace, and the first part of the purification much more cheaply in a Bessemer converter or open-hearth furnace.
In a very few places the molten cast iron as it issues from the blast furnace is cast directly in these moulds, but in general it is allowed to solidify in pigs, and then remelted either in cupola furnaces or in air furnaces.
Of the two the cupola is very much the more economical of fuel, thanks to the direct transfer of„ heat from the burning coke to the pig iron with which it is in contact.
Thus it comes about that the cupola, because it is so economical, is used for all but the relatively few cases in which the strengthening of the iron by the removal of part of its carbon and the prevention of the absorption of sulphur are so important as to compensate for the greater cost of the air-furnace melt - ing.
- Cupola Furnace for Remelting cast iron of the Pig Iron.
- Cast iron naturally has a high carbon-content, usually between 3 and 4%, because while molten it absorbs carbon greedily from the coke with which it is in contact in the iron blast furnace in which it is made, and in the cupola furnace in which it is remelted for making most castings.
The cupola of the church in the fortress is 2455 ft.
Below the top of the cupola: an attempt to reach the floor by a cutting from the hill-side proved abortive.
This, with its rather handsome cupola, and the twelve minor tombs of Ahmad Shah's children grouped around, contains a few good specimens of fretwork and of inlaid inscriptions.

The tomb is a vault, surmounted by an oblong stone monument, with a stele at the head and feet; and a cupola, supported by four walls, covers the whole in the case of sheikhs tombs and those of the wealthy.
To-day more than eight-tenths of the copper ores of the world are reduced to impure copper bars or to fine copper at the mines; and where the character of the ore permits, the cupola furnace is found more economical in both fuel and labour than the reverberatory.
In America the usual method is to roast ores or concentrates so that the matte yielded by either the reverberatory or cupola furnace will run from 45 to 50% in copper, and then to transfer to the Bessemer converter, which blows it up to 99%.
In Butte, Montana, reverberatories have in the past been preferred to cupola furnaces, as the charge has consisted mainly of fine roasted concentrates; but the cupola is gaining ground there.
The home of cupola smelting was Germany, where it has never ceased to make steady progress.
In Mansfeld brick cupola furnaces are without a rival in size, equipment and performance.
The low percentage of sulphur in the roasted ore is little more than enough to produce a matte of 40 to 45%, and therefore the escaping gases are better fitted than those of most copper cupola furnaces for burning in a stove.
In the United States the cupola has undergone a radical modification in being built of water-jacketed sections.
The first water-jacketed cupola which came into general use was a circular inverted cone, with a slight taper, of 36 inches diameter at the tuyeres, and composed of an outer and an inner metal shell, between which water circulated.
It is smelted raw with hot blast in cupola furnaces, the largest being 2 10 in.
With pyritic smelting a sulphuretted copper ore, fed into a cupola in the morning, can be passed directly to the converter, blown up to metal, and shipped as 99% bars by evening - an operation which formerly, with heap roasting of the ore and repeated roasting of the mattes in stalls, would have occupied not less than four months.
It is noteworthy for a splendid ruined mosque built by the Seljuk, Isa Bey II., of Aidin, in 13 7 5, which contains magnificent columns: for a castle, near which lie remains of the pendentives from the cupola of the great cathedral of St John, now deeply buried in its own ruins: and for an aqueduct, Turkish baths and mosque-tombs.
