Question: Bob and wheel is the common name for a metrical device most famously used by the poet whose body of work includes some of the most well-regarded poetry written in what?
Context: This is a list of Chinese poems in the broad sense of referring to those poems which have been written in Chinese, translated from Chinese, authored by a Chinese poet, or which have a Chinese geographic origin.  Chinese poems are poetry written, spoken, or chanted in the Chinese language.  The various versions of Chinese include Classical Chinese, Standard Chinese and other historical and vernacular types.  In other words, "Chinese poetry" refers to poetry written or spoken in the Chinese language.  The various versions of Chinese poetry, as known historically and to the general knowledge of the modern world, include two primary types, "Classical Chinese poetry" and "modern Chinese poetry". Blank verse is poetry written with regular metrical but unrhymed lines, almost always in iambic pentameter.  It has been described as "probably the most common and influential form that English poetry has taken since the 16th century", and Paul Fussell has estimated that "about three quarters of all English poetry is in blank verse". Scottish literature in the eighteenth century is literature written in Scotland or by Scottish writers in the eighteenth century.  It includes literature written in English, Scottish Gaelic and Scots, in forms including poetry, drama and novels.  After the Union in 1707 Scottish literature developed a distinct national identity.  Allan Ramsay led a "vernacular revival", the trend for pastoral poetry and developed the Habbie stanza.  He was part of a community of poets working in Scots and English who included William Hamilton of Gilbertfield, Robert Crawford, Alexander Ross, William Hamilton of Bangour, Alison Rutherford Cockburn, and James Thompson.  The eighteenth century was also a period of innovation in Gaelic vernacular poetry.  Major figures included Rob Donn Mackay, Donnchadh Bàn Mac an t-Saoir, Uillean Ross and Alasdair mac Mhaighstir Alasdair, who helped inspire a new form of nature poetry.  James Macpherson was the first Scottish poet to gain an international reputation, claiming to have found poetry written by Ossian.  Robert Burns is widely regarded as the national poet. The Wangchuan ji () is a collection of Tang poetry written by the two poets Wang Wei (王維) and Pei Di (裴迪), also known in other ways, such as Wheel River Collection.  The verses are based on a series of twenty scenes, inspired by the sights available at Wang Wei's retirement estate: each one forms the topic for a pair of one five-character quatrains, one by each of the poetic pair, first Wang Wei, then Pei Di.  Besides the long-term interest in these verses, in China, this anthology has created much interest around the world, including numerous translations, especially Wang's version of "Deer Park".  Several complete translations of the whole work have been done, in English .  A series of "Twenty Scenes" of Wangchuan were done as a painting series.  The Wangchuan poems (and related artworks) form an important part of traditional Chinese Shan shui landscape painting and Shanshui poetry development.  There are clear indications of the influence of the Six Dynasties poet early exemplar of landscape genre poetry Xie Lingyun's poems on topics, partly inspired by his family estate, in what is today Zhejiang.  The considerable influence of Pei Di and Wang Wei's "Wangchuan ji" shows in much subsequent painting, music, and poetry. Martín Adán (Lima, 1908 - 1985), pseudonym of Rafael de la Fuente Benavides, was a Peruvian poet whose body of work is notable for its hermeticism and metaphysical depth. Jacinta Escudos, born in San Salvador, is a writer whose body of work includes novels, short stories, poetry, creative nonfiction, and journalistic chronicles that have been published in such Central American daily outlets as "La Nación" (Costa Rica), "La Prensa Gráfica" (El Salvador), and "El Nuevo Diario" (Nicaragua).  While she primarily writes in Spanish, she is fluent in English, German, and French, having worked as a translator for several years.  She has traveled extensively and lived in various Central American countries and Europe.  The pluralities of these cultural and geographical fusions manifest themselves in her literary production and intellectual thought.  Her novel, "A-B-Sudario" (Alfaguara, 2003), was awarded the Mario Monteforte Toledo Central American Prize for Fiction ("Premio Centroamericano de Novela Mario Monteforte Toledo").  She has also received residencies by "La Maison des Écrivains Étrangers et des Traducteurs" in Saint-Nazaire, France and "Heinrich Böll Haus" in Langenbroich, Germany. Bob and wheel is the common name for a metrical device most famously used by the Pearl Poet in "Sir Gawain and the Green Knight".  The feature is found mainly in Middle English and Middle Scots poetry, where the bob and wheel occur typically at the end of a stanza.  The "bob" is a very short line, sometimes of only two syllables, followed by the "wheel", longer lines with internal rhyme.  There are at least forty known examples of bob and wheel use, but the origin of the form is obscure.  It seems to predate the Pearl Poet.  Bob and wheel is not used often in modern poetry. Japanese poetry is poetry of or typical of Japan, or written, spoken, or chanted in the Japanese language, which includes Old Japanese, Early Middle Japanese, Late Middle Japanese, and Modern Japanese, and some poetry in Japan which was written in the Chinese language or "ryūka" from the Okinawa Islands: it is possible to make a more accurate distinction between Japanese poetry written in Japan or by Japanese people in other languages versus that written in the Japanese language by speaking of Japanese-language poetry.  Much of the literary record of Japanese poetry begins when Japanese poets encountered Chinese poetry during the Tang dynasty (although the Chinese classic anthology of poetry, "Shijing", was well known by the literati of Japan by the 6th century).  Under the influence of the Chinese poets of this era Japanese began to compose poetry in Chinese "kanshi"); and, as part of this tradition, poetry in Japan tended to be intimately associated with pictorial painting, partly because of the influence of Chinese arts, and the tradition of the use of ink and brush for both writing and drawing.  It took several hundred years to digest the foreign impact and make it an integral part of Japanese culture and to merge this "kanshi" poetry into a Japanese language literary tradition, and then later to develop the diversity of unique poetic forms of native poetry, such as "waka", "haikai", and other more Japanese poetic specialties.  For example, in the "Tale of Genji" both "kanshi" and "waka" are frequently mentioned.  The history of Japanese poetry goes from an early semi-historical/mythological phase, through the early Old Japanese literature inclusions, just before the Nara period, the Nara period itself (710 to 794), the Heian period (794 to 1185), the Kamakura period (1185 to 1333), and so on, up through the poetically important Edo period (1603 and 1867, also known as "Tokugawa") and modern times; however, the history of poetry often is different than socio-political history. The KL-43 is a portable, electronic cipher device used by the United States and the NATO from the early 1980s.  The machine, manufactured by TRW, is an adaptation of language translator technology, and includes a keyboard for input and an LCD for output.  It also contains a built-in modem, a telephone coupler, and the facility for connecting to a printer.  A version of the KL-43 was famously used by Oliver North to communicate with his assistant, Fawn Hall, and others while managing clandestine operations in Nicaragua in support of the "Contra" rebels.  The device was paraded in front of cameras during the Iran-Contra congressional hearings. The "Pearl Poet", or the "Gawain Poet", is the name given to the author of "Pearl", an alliterative poem written in 14th-century Middle English.  Its author appears also to have written the poems "Sir Gawain and the Green Knight", "Patience", and "Cleanness"; some scholars suggest the author may also have composed "Saint Erkenwald".  Save for the last (found in BL-MS "Harley 2250"), all these works are known from a single surviving manuscript, the British Library holding "Cotton Nero A.x".  This body of work includes some of the most well-regarded poetry written in Middle English.
