The hemispherical dome is a surface formed by the rotation around a vertical axis of a semicircle. Like other "rotational domes" formed by the rotation of a curve around a vertical axis, hemispherical domes have circular bases and horizontal sections and are a type of "circular dome" for that reason.
The apparent lightness of its dome may be attributed to both even lighting and the unusual lack of pendentives, with the dome on its circular entablature above eight columns instead. [155] Its use of bulbous domes on the lantern and side towers was also unusual in Italy, where bulbous domes remained rare. [94]
A tholos (pl.: tholoi; from Ancient Greek θόλος, meaning "conical roof" [1] or "dome"), in Latin tholus (pl.: tholi), is a form of building that was widely used in the classical world. It is a round structure with a circular wall and a roof, usually built upon a couple of steps (a podium), and often with a ring of columns supporting a ...
A rotunda (from Latin rotundus) is any roofed building with a circular ground plan, and sometimes covered by a dome. It may also refer to a round room within a building (a famous example being the one below the dome of the United States Capitol in Washington, D.C.). The Pantheon in Rome is perhaps the most famous, and is the most influential ...
The thickness of the dome is not included. If the inner diameter of a dome is not available, a footnote follows the structure's name. If a dome has an elliptical rather than circular shape, the dome's shorter dimension (i.e. width) is used for ranking, and, contra convention, its dimensions are listed as width × length, rather than length × ...
Circular channels on the upper surface of the oculus also support the idea that this lantern, perhaps itself domed, was the rotating dome referred to in written accounts. [43] According to Suetonius, the Domus Aurea had a dome that perpetually rotated on its base in imitation of the sky. [44]
A large dome was built in 1881–1882 over the circular courtyard of the Devonshire Royal Hospital in England with a diameter of 156 feet. [46] It used radial trussed ribs with no diagonal ties. [41] The dome of Pavia Cathedral, a building started in 1488, was completed with a large octagonal dome joined to the basilica plan of the church. [47]
An oculus (from Latin oculus 'eye'; pl.: oculi) is a circular opening in the center of a dome or in a wall. Originating in classical architecture, it is a feature of Byzantine and Neoclassical architecture. A horizontal oculus in the center of a dome is also called opaion (from Ancient Greek ὀπαῖον '(smoke) hole'; pl.: opaia).
