This book is devoted to the study of the worldview of the Greeks of the Archaic period. The sources were epic (mainly Homer), poetic, geographical and other works of antiquity, depicting the oceanic voyages of Greek heroes - Odysseus, But, Hercules, the Argonauts, Oresteia. The author reconstructs the mental map of the world that existed in the minds of the archaic Greeks and shows that the oceanic voyages of heroes around the ecumene, described by ancient authors, were commonplace and fully consistent with the ideas of that time about the geography of the world. Roman mosaics of the 3rd century were used in the design. n. e. "Odysseus and the Sirens" from the Bardo Museum (Tunisia).
