    Other great kings and paladins are lost in the dim shadows oflong-past centuries, but Arthur still reigns in Camelot and his knightsstill ride forth to seek the Grail. "No little thing shall be The gentle music of the bygone years, Long past to us with all their hopes and fears."So wrote the poet William Morris in _The Earthly Paradise_. And surelyit is no small debt of gratitude we owe the troubadours and chroniclersand poets who through many centuries have sung of Arthur and hischampions, each adding to the song the gifts of his own imagination, sobuilding from simple folk-tales one of the most magnificent and movingstories in all literature.This debt perhaps we owe in greatest measure to three men; to Chrétiende Troies, a Frenchman, who in the twelfth century put many of the oldArthurian legends into verse; to Sir Thomas Malory, who first wrote outmost of the stories in English prose, and whose book, the _MorteDarthur_, was printed by William Caxton, the first English printer, in1485; and to Alfred, Lord Tennyson, who in his series of poems entitledthe _Idylls of the King_ retold the legends in new and beautiful guisein the nineteenth century.The history of Arthur is so shrouded in the mists of early England thatit is difficult to tell exactly who and what he was. There probably wasan actual Arthur, who lived in the island of Britain in the sixthcentury, but probably he was not a king nor even a prince. It seems mostlikely that he was a chieftain who led his countrymen to victory againstthe invading English about the year 500. So proud were his countrymen ofhis victories that they began to invent imaginary stories of his prowessto add to the fame of their hero, just as among all peoples legends soonspring up about the name of a great leader. As each man told the featsof Arthur he contributed those details that appealed most to his ownfancy and each was apt to think of the hero as a man of his own time,dressing and speaking and living as his own kings and princes did, withthe result that when we come to the twelfth century we find Geoffrey ofMonmouth, in his _History of the Kings of Britain_, describing Arthurno longer as a half-barbarous Briton, wearing rude armor, his arms andlegs bare, but instead as a most Christian king, the flower of mediævalchivalry, decked out in all the gorgeous trappings of a knight of theCrusades.As the story of Arthur grew it attracted to itself popular legends ofall kinds. Its roots were in Britain and the chief threads in its fabricremained British-Celtic. The next most important threads were those thatwere added by the Celtic chroniclers of Ireland. Then stories that werenot Celtic at all were woven into the legend, some from Germanicsources, which the Saxons or the descendants of the Franks may havecontributed, and others that came from the Orient, which may have beenbrought back from the East by men returning from the Crusades. And if itwas the Celts who gave us the most of the material for the stories ofArthur it was the French poets who first wrote out the stories and gavethem enduring form.It was the Frenchman, Chrétien de Troies, who lived at the courts ofChampagne and of Flanders, who put the old legends into verse for thepleasure of the noble lords and ladies that were his patrons. Hecomposed six Arthurian poems. The first, which was written about 1160 orearlier, related the story of Tristram. The next was called _Érec etÉnide_, and told some of the adventures that were later used by Tennysonin his _Geraint and Enid_. The third was _Cligès_, a poem that haslittle to do with the stories of Arthur and his knights as we havethem. Next came the _Conte de la Charrette_, or _Le Chevalier de laCharrette_, which set forth the love of Lancelot and Guinevere. Thenfollowed _Yvain_, or _Le Chevalier au Lion_, and finally came_Perceval_, or _Le Conte du Graal_, which gives the first account of theHoly Grail.

    Twelve days later, she was stabbed in a Shanghai stairwell. The actions of both police investigators and O'Brien's Chinese modeling agent soon aroused suspicion as her family sought answers from China's opaque legal system. Ultimately, their quest would put them face to face with her accused killer.At once a page-turning murder mystery and a work of deep investigation, And The City Swallowed Them is a true crime nonfiction story based on dozens of interviews with investigators, models, and both the victim's and the convicted murderer's families. The short book moves from Shanghai's back alleys to the seedy underbelly of high fashion, where young models travel alone to strange cities, often with falsified work papers, and sleep ten to an apartment between cover shoots. Set against the backdrop of Shanghai's explosive urbanization, the work also explores the world of China's liudong renkou, or floating population, where the hopes of newcomers from poor villages often turn to dust—leading some to horribly desperate acts.The debut digital title from the writers cooperative Deca, And The City Swallowed Them overturns assumptions about both China’s feared justice system, where the conviction rate for criminals is 99.9 percent, and the glamorous world of international modeling. More than a murder tale, And The City Swallowed Them lays bare the powerful forces that send two families on a collision course from distant sides of the Pacific.

    It has a reputation as a dry and difficult subject, a glorified form of geometry complicated by tedious computation. In this book, Eli Maor draws on his remarkable talents as a guide to the world of numbers to dispel that view. Rejecting the usual arid descriptions of sine, cosine, and their trigonometric relatives, he brings the subject to life in a compelling blend of history, biography, and mathematics. He presents both a survey of the main elements of trigonometry and a unique account of its vital contribution to science and social development. Woven together in a tapestry of entertaining stories, scientific curiosities, and educational insights, the book more than lives up to the title Trigonometric Delights.Maor, whose previous books have demystified the concept of infinity and the unusual number "e," begins by examining the "proto-trigonometry" of the Egyptian pyramid builders. He shows how Greek astronomers developed the first true trigonometry. He traces the slow emergence of modern, analytical trigonometry, recounting its colorful origins in Renaissance Europe's quest for more accurate artillery, more precise clocks, and more pleasing musical instruments. Along the way, we see trigonometry at work in, for example, the struggle of the famous mapmaker Gerardus Mercator to represent the curved earth on a flat sheet of paper; we see how M. C. Escher used geometric progressions in his art; and we learn how the toy Spirograph uses epicycles and hypocycles.Maor also sketches the lives of some of the intriguing figures who have shaped four thousand years of trigonometric history. We meet, for instance, the Renaissance scholar Regiomontanus, who is rumored to have been poisoned for insulting a colleague, and Maria Agnesi, an eighteenth-century Italian genius who gave up mathematics to work with the poor--but not before she investigated a special curve that, due to mistranslation, bears the unfortunate name "the witch of Agnesi." The book is richly illustrated, including rare prints from the author's own collection. Trigonometric Delights will change forever our view of a once dreaded subject.
