Hagia Sophia is a former patriarchal basilica, later a mosque, now a museum in Istanbul, Turkey. Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture. It was the largest cathedral ever built in the world for nearly a thousand years, until the completion of the Seville Cathedral in 1520. The current building was originally constructed as a church between A.D. 532 and 537 on the orders of the Byzantine Emperor Justinian, and was in fact the third Church of the Holy Wisdom to occupy the site.

These volutes, or scrolls, when viewed from the side, appear to meet in the middle, and form a wavy line over the echinus. The intervals of the spiral coils are slightly hollowed, in order to bring them into more relief, and in this way the so-called channel is formed, which is continued in the horizontal portion which connects the volutes.

"The ordinary self-acting planing machine. Its action bears no resemblance to the familiar process of wood planing, but is analogous to that by which the successive cuts of a narrow tool produce a cylindrical surface in a slide lathe. A transverse table carries the work and forces it against the tool, which is stationary while making its cut, but between the cuts has a slight "feed" motion along its horizontal slide." &mdash;The Encyclopedia Britannica, 1903

The slide which carries the tool is in their case horizontal, and its short but variable strokes are in a direction transverse to the bed, along which it can travel, just as a slide-rest travels along a lathe bed." &mdash;The Encyclopedia Britannica, 1903

"It was in Central France, and mainly along the Loire, that the systematic development of vaulted church architecture began. Naves covered with barrel-vaults, sometimes of pointed section, appear in a number of large churches built during the eleventh and twelfth centuries, with apsidal and transeptal chapels and aisles carried around the apse, as in the imposing church of St. Sernin at Toulouse, in Provence. The thrust of these ponderous vaults was clumsily resisted by half-barrel vaults over the side aisles, transmitting the strain to massive side-walls."
