DORNBURG  , a

town of Germany, in the grand-duchy of Saxe-Weimar, romantically situated on a hill 400 ft. above the Saale, on the railway Grossheringen-Jena and 7 in . N.E. of the latter . Pop . 700 . Dornburg is an ancient town, but is chiefly famous for its three grand-ducal castles . Of these, the Altes Schloss is built on the site of an imperial stronghold (Kaiserpfalz), once a bulwark against the Slays, often a residence of the emperors Otto II. and Otto III., and where the emperor Henry II. held a diet in 1005; the Neues Schloss in Italian style of architecture, built 1728-1748, with pretty gardens . Here Goethe was often a guest, " healing the blows of fate and the wounds of the heart in Dornburg." The third and southernmoseof the three is the so-called Stohmannsches Rittergut, purchased in 1824 and fitted as.a Dorner set to work upon a history of, the development of the doctrine of the person of Christ, Entwicklungsgeschichte der Lehre von der Person Christi . He published the first part of it in 1835, the year in which Strauss, his colleague, gave to the public his Life of Jesus; completed it in 1839, and afterwards considerably enlarged it for a second edition (1845-1856) . It was an indirect reply to Strauss, which showed " profound learning, objectivity of judgment, and fine appreciation of the moving ideas of history" (Otto Pfleiderer) . The author at once took high rank as a theologian and historian, and in 1839 was invited to Kiel as professor ordinarius . It was here that he produced, amongst other works, Das Princip unserer Kirche nach dem innern Verhaltniss seiner zwei Seiten betrachtet (1841) . In 1843 he removed as professor of theology to Konigsberg .

Thence he was called to

Bonn in 1847, and to Gottingen in 1853 . Finally in 1862 he settled in the same capacity at Berlin, where he was a member of the supreme consistorial council . A few years later (1867) he published his valuable Geschichte der protestantischen Theologie (Eng. trans., History of Protestant Theology,2 vols.;1871), in which he " developed and elaborated, as Pfleiderer says, " his own convictions by his diligent and loving study of the history of the Church's thought and belief." The theological positions to which he ultimately attained are best seen in his Christliche Glaubenslehre, published shortly before his death (1879-1881) . It is "a work extremely rich in thought and matter . It takes the reader through a mass of historical material by the examination and discussion of ancient and modern teachers, and so leads up to the author's own view, which is mostly one intermediate between the opposite extremes, and appears as a more or less successful synthesis of antagonistic theses " (Pfleiderer) . The companion work, System der christlichen Sittenlehre, was published by his son August Dorner in 1886 . He also contributed articles to Herzog-Hauck's Realencyklopeidie, and was the founder and for many years one of the editors of the Jahrbiicher fur deutsche Theologie . He died at Wiesbaden oh the 8th of July 1884 . One of the most noteworthy of the " mediating " theologians, he has been ranked with Friedrich Schleiermacher, J . A . W . Neander, Karl Nitzsch, Julius Muller. and Richard Rothe .

His son, AuousT (b . 1846), after studying at Berlin and acting as Repetent at Gottingen (1870-1873), became professor of theology and co-director of the theological

seminary at Wittenberg . Amongst his works is Augustinus, sein theologisches System and seine religionsphilosoph . Anschauung (1873), and he is the author of the article on Isaac Dorner in the Allgemeine deutsche Biographic .
