This thesis examines the depiction of Etruscan demons and sepulchral deities, with particular emphasis on the Etruscan understanding of the afterlife and their conception of the soul. The Etruscans, known for their profound religiosity and the central role of divination in everyday life, developed a rich tradition of beliefs in the context of death, which is explored in this work. Through the analysis of sources such as the Capua tile, the Zagreb Linen Book, and the Liver of Piacenza, insights are provided into religious practices and representations of the Etruscan afterlife deities. The role of prophets, particularly Tages and Vegoia, who held a central place in the Etruscan divination system, is also highlighted. The thesis presents the deities of the underworld, including Aita, Phersipnai, Śuri, Catha, and Lur, whose artistic depictions and symbolism point to their significance in the context of death and transition to the afterlife. The study also analyzes the underworld demons Tuchulcha, Charun, Lasa, and Vanth, as well as the psychopomp Turms, whose role is crucial in Etruscan eschatology. Furthermore, the thesis explores the syncretism of symbols associated with these deities, demons, and psychopomps. The final chapter focuses on the Etruscan perception of the soul, death, and the journey to the underworld, with special attention to the enigmatic figure of Phersu, significant in the context of funerary games. Tomb frescoes further illustrate the journey to the underworld, providing a visual representation of the Etruscan understanding of the afterlife.
