The eastern arm shows considerable diversity. In England it is generally long and may have two distinct sections, both choir and presbytery. It is often square ended or has a projecting Lady Chapel, dedicated to the Virgin Mary. In France the eastern end is often polygonal and surrounded by a walkway called an ambulatory and sometimes a ring of chapels called a "chevet". While German churches are often similar to those of France, in Italy, the eastern projection beyond the transept is usually just a shallow apsidal chapel containing the sanctuary, as at Florence Cathedral.
What is the ring of chapels found in the eastern end of French chapels known as?
chevet

The 16th and 17th centuries are regarded as something of a "dark age" in Greek history, with the prospect of overthrowing Ottoman rule appearing remote with only the Ionian islands remaining free of Turkish domination. Corfu withstood three major sieges in 1537, 1571 and 1716 all of which resulted in the repulsion of the Ottomans. However, in the 18th century, there arose through shipping a wealthy and dispersed Greek merchant class. These merchants came to dominate trade within the Ottoman Empire, establishing communities throughout the Mediterranean, the Balkans, and Western Europe. Though the Ottoman conquest had cut Greece off from significant European intellectual movements such as the Reformation and the Enlightenment, these ideas together with the ideals of the French Revolution and romantic nationalism began to penetrate the Greek world via the mercantile diaspora.[page needed] In the late 18th century, Rigas Feraios, the first revolutionary to envision an independent Greek state, published a series of documents relating to Greek independence, including but not limited to a national anthem and the first detailed map of Greece, in Vienna, and was murdered by Ottoman agents in 1798.[page needed]

In late 1977, music writers for Sounds first used the terms "New Musick" and "post punk" to describe British acts such as Siouxsie and the Banshees and Wire, who began experimenting with sounds, lyrics and aesthetics that differed significantly from their punk contemporaries. Writer Jon Savage described some of these early developments as exploring "harsh urban scrapings [,] controlled white noise" and "massively accented drumming". In January 1978, singer John Lydon (then known as Johnny Rotten) announced the break-up of his pioneering punk band the Sex Pistols, citing his disillusionment with punk's musical predictability and cooption by commercial interests, as well as his desire to explore more diverse interests.
Which band's lead singer was Johnny Rotten?
Sex Pistols
