The research object of the present text is 3 Polish, 11 Slovakian, and 6 Czech male anthroponyms, derived from 22 Roman mythological names. The main aims are to present the list of the analyzed anthroponyms and to speak on their meanings. The researched anthroponyms are divided into two major groups according to: 1) the type of the basic word, used during the process of name derivation, as a part of speech; 2) the type formed from a Roman mythological name, i. e. if the West-Slavonic anthroponym is derived from its form of Nom. sg. or from its root. Additional extralinguistic classification is made according to the canonization of the researched names, i. e. if it is a name of a saint, and, if the saint is canonized only by the Orthodox Church, by the Catholic one, or by both of them.
