Streszczenie
The text presents the results of a research on the demythonymic eponyms in Polish and French language, i.e. lexical units, which derive from proper names appearing in the fi ctional space of classical myths (mythonyms). The primary goal of the study is to determine the cultural code and lexical fi elds that are represented by demythonymic eponyms. The author also considers the structure of eponyms, distinguishing among them one-element/univerbal and complex/pluriverbal forms. An insight into the onomastic categorization of the demythonymic eponyms allows to establish that in their onymic basis they refer to the proper names of all possible types.
