Abstract: The article attempts to study the Latin text of the chronicle “Historia de regibus Gothorum, Wandalorum et Sueborum” written by the famous 17th c. theologist and scholar Isidoro de Sevilla by means of advanced methods of intellectual text analysis. The main goal is to verify the hypothesis that the author had ideas about the hierarchy of barbarians. The main focus is to clarify the implicit semantic relationship between different parts of the chronicle in order to find out the author’s attitude to these three barbaric groups. The analysis of the text was performed with the R programming language. The specific method is that of latent semantic analysis providing for comparing clustering of texts on the basis of semantic space designed through the singular decomposition of term-document matrix. The research novelty of the study is that it is the first time when a full cycle latent semantic analysis of a Medieval Latin text has been performed which covered the text preprocessing, the creation of the semantic space and the calculation of the semantic similarity of texts on the basis of cosine similarity measure. The analysis results suggest that Isidoro de Sevilla really built the hierarchy of three barbarian groups providing greater similarity to the description of the Visigoths and the Suebi and putting the Vandals apart.
