The efforts and results of the research work of the 19th-century personalities who prepared the Czechoslavic Ethnographic Exhibition was continued by other scientists from ethnography and other disciplines dealing with folk culture in the 20th century. Dušan Jurkovič, Zdeněk Wirth and Václav Mencl as well as others were among the most significant experts in the branch of vernacular architecture. Antonín Kurial, a student of Prof. Groha and a university teacher, followed their traces and learned from their results. He succeeded in developing the theories about the documentation of vernacular architecture into a fully- fledged practice. Together with his students at Brno University of Technology, he tried to achieve the best possible way of documentation. After World War II, he started to make an inventory of and to localize more than 1 300 buildings and to survey the selected vernacular buildings from Moravia and Silesia in the measuring scale 1:50 and 1:25. Eastern Moravia, especially the regions of Luhačovské Zálesí and southern Wallachia as well as the villages with timbered architecture in the Vsetín area are abundantly represented in his collection prepared for the Atlas of Vernacular Architecture. The collected documents are published in the form of a printed Catalogue of Vernacular Architecture in particular districts and they are considered to be a unique form of detailed documentation of vernacular buildings in Central Europe.
The structure analysis of toponymy (a sum of toponyms) in a certain territory (language) leads to the typology of language properties (ways of creation, motivations, etc.), on the basis of which it is possible, while taking into account the use of particular structure elements, to define, among other things, also their chronological
layers and spread within an area. This method called the method of small types is aninvention of Czech topomastics (V. Šmilauer: Osídlení Čech ve světle místních jmen [The Settlement in Bohemia in the Light of Local Names]. 1960). Based on the analysis of the mentioned space toponymy, which was conducted using the above method, the gradual spreading of (early)medieval old settlement area of Moravia towards the East is demonstrated on the maps with the representative types of toponyms. This confirms the property of local dialects as an archaic edge of the Czech language. The
“Rumanian” elements are exclusively sub-sequent and thematically specified lexical transfers, which have been spread throughout the Carpathians as well as the Balkans. The “movement” is not understood in the sense of migration, but as an extension of the old space. The interpretation of the all-Carpathian dialectology is included, which clearly demonstrates the concept of “Wallachian” colonization and the kinds of migrations as a cultural phenomenon. Its lexical nature is explained through that.
