The vision of the End of Times in Joachim of Fiore’s apocalyptic conception presents one of the most interesting interpretations of the end of the world in relation to events and historical figures and presents an attempt to look into the future made by the 12th-century Calabyan Abbot Joachim of Fiore on the basis of the book of the Holy Bible, especially the Apocalypse of Saint John. The purpos of the thesis is to introduce the reader to the very form of the medieval exeget – Joachim of Fiore as well as the concept of tripartite and interpretation of history in the Trinitarian context created by him. In the light of the concept mentioned above, the vision of the Calabyan Abbot was presented regarding the end of times, preceded by an explanation of exegetical methods used by the abbot (especially biblical typology and the principle of compatibility of both Testaments in relation to the entire history of the Chosen People and Christianity).

The thesis contains both Latin fragments of Joachim’s manuscripts and translations of them into Polish.
