emperor qianlong (1711-1799)
Charles-Nicolas Cochin was a French engraver, designer, writer, and art critic. To distinguish him from his father of the same name, he is variously called Charles-Nicolas Cochin the Younger, Charles-Nicolas Cochin the son, or Charles-Nicolas Cochin II.
More than fifteen hundred works by Cochin can be identified. They include historical subjects, book illustrations, and portraits in pencil and crayon. The richest collection of his engravings, apparently selected by himself, is in the Royal Library, now part of the Bibliothèque nationale.
Emperor Daoguang, also known by his temple name Emperor Xuanzong of Qing, born Aixing-Gioro Mianning, was the seventh emperor of the Qing Dynasty and the sixth Qing emperor to rule China from 1820 to 1850.
As emperor and head of the country, Daoguang was weak. His 30-year reign was accompanied by internal and external problems, chief among them the First Opium War and the outbreak of the Taiping Rebellion. The country he led also experienced growing economic tensions, sectarian instability, and active foreign interference, which eventually led to the collapse of the Qing dynasty in 1911.
