Danubian

Danubian is a hypothetical language family, forming a branch of Europic (together with Indo-European and Hesperic) once spoken in the Danube basin. One of these languages, the language of the Vinča culture, may have been the first human language ever written, if the engravings on various artifacts of that culture are indeed writing.

Taylor Selseth has developed a Danubian conlang, Alpic, in the framework of the League of Lost Languages.
