Hettner's day have fallen into discredit, and at times losing sight of the main issues of literary development over questions of social evolution, this work belongs to the best histories that the 19th century produced. Hettner's judgment is sound and his point of view always original and stimulating. His other works include _Griechische Reiseskizzen_ (1853), _Das moderne Drama_ (1852)--a book that arose from a correspondence with Gottfried Keller--_Italienische Studien_ (1879), and several works descriptive of the Dresden art collections. His _Kleine Schriften_ were collected and published in 1884. See A. Stern, _Hermann Hettner, ein Lebensbild_ (1885); H. Spitzer, _H. Hettners kunstphilosophische Anfange und Literaturasthetik_ (1903). HETTSTEDT, a town of Germany, in Prussian Saxony, on the Wipper, and at the junction of the railways Berlin-Blankenheim and Hettstedt-Halle, 23 m. N.W. of the last town. Pop. (1905), 9230. It has a Roman Catholic and four Evangelical churches, and has manufactures of machinery, pianofortes and artificial manure. In the neighbourhood are mines of argentiferous copper, and the surrounding district and villages are occupied with smelting and similar works. Silver and sulphuric acid are the other chief products; nickel and gold are also found in small quantities. In the Kaiser Friedrich mine close by, the first steam-engine in Germany was erected on the 23rd of August 1785. Hettstedt is mentioned as early as 1046; in 1220 it possessed a castle; and in 1380 it received civic privileges. When the countship of Mansfeld was sequestrated, Hettstedt came into the possession of Saxony, passing to Prussia in 1815.
