“900 thousand rivers speak the Pelasgian language”

The trilogy examines the hypothesis that thousands of hydrographic names around the world hide common roots that refer to a very ancient, pre-Greek linguistic form, called "Pelasgian." The author collects extensive material from rivers, lakes, and place names and attempts to show that recurring phonetic types and linguistic patterns are not random but constitute remnants of an ancient linguistic presence.

In all the books, a research methodology is followed that combines linguistics, toponymy, comparative analysis, and historical sources. The involvement of a scientific advisor strengthens the technical nature of the study, while the presentation is organized in a way that builds from the general to the specific: global examples, phoneme correlations, and conclusions about possible cultural routes in prehistory.

The overall core of the trilogy is the idea that the names of water bodies preserve linguistic traces that precede today’s nations and languages. The author argues that these traces indicate a widespread diffusion of the Pelasgian or pre-Greek language, which left imprints from Europe to Asia and beyond. Despite the hypothetical nature of some conclusions, the work functions as a large, unified attempt to interpret global toponymy through a common proto-linguistic line.
