This paper analyzes the role of myth in Prawda starowieku (The Truth of the Ages), the first part of the Na wysokiej połoninie (On the High Uplands) tetralogy by Polish author Stanisław Vincenz. For Vincenz, an anti-modernist, myth represents a continuation of the Homeric myth-making tradition. He utilizes it to create an idealized image of the Hutsuls, a Rusyn ethnic group. The Polish author assigns this highland community, the Hutsulšč’yna, as a collective protagonist with a distinctive mythical worldview. Time and space, according to Vincenz's Hutsuls, are ideal, or "sacred" and thusly unchanging, in line with Mircea Eliade's thesis about archaic and religious communities. They consider their way of life divine, seeing themselves as "children of God." In his work he wanted to present his vision of a traditional community, in which he saw a solution to the modern human spiritual and moral crisis of the contemporary Western culture, which he believed was heading towards spiritual and moral decay. The aim of this paper is to analyze myth in the worldview of Vincenz's Hutsuls and explain its characteristics and functions in accordance with the author's intent. The first part of the paper presents essential information about the author's biography, Stanisław Vincenz, his literary work, and the inspiration and reasons for writing the Na wysokiej połoninie tetralogy. The second part involves analyzing the myth in Prawda starowieku. The first chapter examines myth in a literary theory sense. The second chapter focuses on the narrator. The third chapter is dedicated to the worldview of the idealized Hutsuls. The fourth and fifth chapters deal with the mythical and "sacred" space and time in which these Hutsuls live.
