Onion dome Totally Explained

Everything about Onion Dome totally explained

An onion dome (Russian: луковичная глава, lúkovichnaya glava) is a type of architectural dome usually associated with Russian Orthodox churches. Such a dome is larger in diameter than the drum it's set upon and its height usually exceeds its width. These bulbous structures taper smoothly to a point, and strongly resemble the onion, after which they're named.
Other important types of Orthodox cupolas are antique helmet domes (for example, those of the Saint Sophia Cathedral in Novgorod and Assumption Cathedral in Vladimir), Ukrainian pear domes (Saint Sophia Cathedral in Kiev), and Baroque bud domes (St. Andrew's Church in Kiev).

History

Art historians disagree when and why onion domes became a typical feature of Russian architecture. Byzantine churches and architecture of Kievan Rus were characterized by broader, flatter domes without a special framework erected above the drum. In contrast to this ancient form, each drum of a Russian church is surmounted by a special structure of metal or timber, which is lined with sheet iron or tiles.
By the end of the nineteenth century, most Russian churches from before the Petrine period had bulbous domes. The largest onion domes were erected in the seventeenth century in the area around Yaroslavl, incidentally famous for its large onions. Quite a few had more complicated bud-shaped domes, whose form derived from Baroque models of the late seventeenth century. Pear-shaped domes are usually associated with Ukrainian Baroque, while cone-shaped domes are typical for Orthodox churches of Transcaucasia.

Traditional view

The earliest academic researchers of Russian architecture pointed out that Russian icons painted before the Mongol invasion of Rus don't feature churches with onion domes. Furthermore, two highly venerated pre-Mongol churches that have never been rebuilt—the Assumption Cathedral and the Cathedral of St. Demetrius in Vladimir—uniquely display golden helmet domes. Restoration works on several other ancient churches revealed some fragments of former helmet-like domes below newer onion cupolas.
   Based on these findings, it was concluded that ancient Russian churches were helmet-shaped while onion domes had been introduced considerably later. It was posited that onion domes first appeared during the reign of Ivan the Terrible. Indeed, the bulbous, wildly coloured domes of Saint Basil's Cathedral have not been altered since the reign of Ivan's son Fyodor I, clearly indicating that onion domes did exist in sixteenth-century Russia.
   Some scholars postulated that onion domes were borrowed by Russians from Muslim countries, probably from the Khanate of Kazan, whose conquest Ivan the Terrible commemorated by erecting St. Basil's Cathedral. Others argued that onion domes first appeared in Russian wooden architecture, above tent-like churches. According to this theory, onion domes were strictly utilitarian, as they prevented snow from piling on the roof.
   This theory became firmly entrenched in Soviet architectural theory. Based on the notion that onion domes didn't exist in Russia before the mid-sixteenth century, restoration works on churches built before the seventeenth century have routinely involved replacement of onion domes with "more authentic" helmet-shaped domes. One example of such restoration is the Dormition Cathedral in the Moscow Kremlin.

Alternative view

In 1946, the historian Boris Rybakov, while analysing miniatures of ancient Russian chronicles, pointed out that most of them, from the thirteenth century onward, display churches with onion domes rather than helmet domes. Nikolay Voronin, the foremost authority on pre-Mongol Russian architecture, seconded his opinion that onion domes existed in Russia as early as the thirteenth century, although they presumably couldn't be widespread. These findings demonstrated that Russian onion domes couldn't be imported from the Orient, where onion domes didn't replace spherical domes until the fifteenth century.
Sergey Zagraevsky, a modern art historian, surveyed hundreds of Russian icons and miniatures, from the eleventh century onward. He concluded that most icons painted after the Mongol invasion of Rus display only onion domes. First onion domes displayed on some pictures of twelfth century (two miniatures from Dobrylov Evangelie). He found only one icon from the late fifteenth century displaying a dome resembling the helmet instead of an onion. His findings led him to dismiss fragments of helmet domes discovered by restorators beneath modern onion domes as post-Petrine stylisations intended to reproduce the familiar forms of Byzantine cupolas. Zagraevsky also indicated that the oldest depictions of the two Vladimir cathedrals represent them as having onion domes, prior to their replacement by classicizing helmet domes.
Zagraevsky explains the ubiquitous appearance of onion domes in the late thirteenth century by the general emphasis on verticality characteristic of Russian architecture from the late twelfth to early fifteenth centuries. At that period, porches, pilasters, vaults and drums were arranged to create a vertical thrust, to make the church seem taller than it was. It seems logical that elongated, or onion, domes were part of the same proto-Gothic trend aimed at achieving pyramidal, vertical emphasis.

Symbolism

Prior to the eighteenth century, the Russian Orthodox Church didn't assign any particular symbolism to the exterior shape of a church. Nevertheless, onion domes are popularly believed to symbolise burning candles. In 1917, noted religious philosopher Prince Yevgeny Trubetskoy argued that the onion shape of Russian church domes may not be explained rationally. According to Trubetskoy, drums crowned by tapering domes were deliberately scored to resemble candles, thus manifesting a certain aesthetic and religious attitude. Another explanation has it that the onion dome was originally regarded as a form reminiscent of the edicula (cubiculum) in the Church of the Holy Sepulchre in Jerusalem.
Onion domes often appear in groups of three, representing the Holy Trinity, or five, representing Jesus Christ and the Four Evangelists. Domes standing alone represent Jesus. Vasily Tatischev, the first to record such interpretation, disapproved of it emphatically. He believed that the five-domed design of churches was propagated by Patriarch Nikon, who liked to compare the central and highest dome with himself and four lateral domes with four other patriarchs of the Orthodox world. There is no other evidence that Nikon ever held such a view.
The domes are often brightly painted: their colours may informally symbolise different aspects of religion. Green, blue, and gold domes are sometimes held to represent the Holy Trinity, the Holy Spirit, and Jesus, respectively. Black ball-shaped domes were once popular in the snowy north of Russia.

Outside Russia

The onion dome isn't only found in Russian Architecture: it was also used extensively in Mughal architecture, which later went on to influence Indo-Gothic architecture. Outside of India, it's also used in Iran and other places in the Middle East and Central Asia. Baroque domes in the shape of an onion (or other vegetables or flower-buds) were common in the Holy Roman Empire as well. The first one was built in 1576 by the architect Hans Holl (1512-1594) on the church of Saint Mary Star Abbey in Augsburg. Usually made of copper sheet, onion domes appear on Catholic churches all over southern Germany, Austria and Northeast Italy.
