Young's designation, successful in English, was only one of several candidates proposed between 1810 and 1867: indo-germanique (Conrad Malte-Brun, 1810), japetisk (Rasmus Christian Rask, 1815), Indo-Germanisch (Julius Klaproth, 1823), indisch-teutsch (F. Schmitthenner, 1826), sanskritisch (Wilhelm von Humboldt, 1827), indokeltisch (A. F. Pott, 1840), arioeuropeo (Graziadio Isaia Ascoli, 1854), Aryan (Max Müller, 1861) and aryaque (H. Chavée, 1867). These men were all polyglots and prodigies in languages. Klaproth, author of the successful German-language candidate, Indo-Germanisch, who criticised Jones for his uncritical method, knew Chinese, Japanese, Tibetan and a number of other languages with their scripts. The concept of a Biblical Ursprache appealed to their imagination. As hope of finding it gradually died they fell back on the growing concept of common Indo-European spoken by nomadic tribes on the plains of Eurasia, and although they made a good case that this language can be deduced by the methods of comparative linguistics, in fact that is not how they obtained it. It was the one case in which their efforts to find the Ursprache succeeded.
