It will be difficult to deal with the "issue of materials" without taking into account the Padua conference in 2001. The linguistic aspect of this conference was entrusted to Rüdiger Schmitt under the title "The language of the Medes, the greatest ignorance". In this regard, Schmidt, who has already done studies on this issue, raised many doubts, which I will briefly mention here. The names "Med" and "Persia" in the ancient discourse often imply a kind of "synonymous" relationship (more or less synonymous) and as a result, it cannot be considered that these two were addressed to a specific and single person. Therefore, it makes it possible to judge whether the address of a person belongs to a particular language or not. Names of persons/names of places, the names reported in Assyrian documents, taking into account the orthographic syllables and matching them, often provide a questionable interpretation.
