He wrote many poems of great literary value, and was one of the earliest and most zealous advocates of Panslavism. In 1831 he published a volume of his sermons, Kazne (Pesth, 1831, 8vo), which were found so eloquent that they were at once translated into several of the modern languages. The revolution in Hungary compelled him to abandon his country. He withdrew to Vienna, where he was made professor of archaeology in 1849, and died there Jan. 29,1852. See For. Quart. Rev.
