Rudolf von Roth (1821-1895) was a prominent German philologist. In this Festgruss, forty four of his colleagues and students presented him papers on various topics on the occasion of his Doctor-Jubiläum. They included luminaries like Theodor Nöldeke, William D. Whitney, Edward V. Arnold, and others. The topics discussed are mostly philological covering a wide range of eastern languages, both Semitic and Indic.
