On the death of his friend and patroness in 1819, he accepted the offer of a professor's chair in Bonn, where he married a daughter of Professor Paulus. This union, as short-lived as the first, was followed by a separation in 1820. In his new position of academic tutor, while he diligently promoted the study of the fine arts and sciences, both of the Ancient and the Moderns, he applied himself with peculiar ardour to Oriental literature, and particularly to the Sanscrit. As a fruit of these studies, he published his _Indian Library_, (2 vols., Bonn, 1820-26); he also set up a press for printing the great Sanscrit work, the _Râmâjana_ (Bonn, 1825). He also edited the Sanscrit text, with a Latin translation, of the Bhagavad-Gita, an episode of the great Indian Epos, the _Mahâbhârata_ (Bonn, 1829). About this period his Oriental studies took, him to France, and afterwards to England, where, in London and in the college libraries of Oxford and Cambridge, and the East India College at Hailesbury, he carefully examined the various collections of Oriental MSS. On his return he was appointed Superintendent of the Museum of Antiquities, and in 1827 delivered at Berlin a course of Lectures on the _Theory and History of the Fine Arts_, (Berlin, 1827). These were followed by his _Criticisms_, (Berlin, 1828), and his _Réflexion sur l'Etude des Langues Asiatiques_, addressed to Sir James Mackintosh. Being accused of a secret leaning to Roman Catholicism, (Kryptocatholicisme,) he ably defended himself in a reply entitled _Explication de quelques Malentendus_, (Berlin, 1828.) A. W. Von Schlegel, besides being a Member of the Legion of Honour, was invested with the decorations of several other Orders. He wrote French with as much facility as his native language, and many French journals were proud to number him among their contributors. He also assisted Madame de Staël in her celebrated work _De l'Allemagne_, and superintended the publication of her posthumous _Considérations sur la Révolution Française_. After this long career of successful literary activity, A. W. Von Schlegel died at Bonn, 12 May, 1845. His death was thus noticed in the _Athenaeum_:--
