Consolatory writings have a long tradition since their structure and the main motifs date back to ancient times. Rhetoric and different philosophical directions conducted a significant impact on consolation and with the arrival of Christianity, it came to a conjunction of Christian and pagan motifs. In this thesis has been done a brief overview of the ancient, medieval and humanistic consolatory tradition. Special emphasis is placed on the main features and the representatives of the ancient consolation because the following periods represented mainly the upgrading and expansion of existing ancient idea. Consolatory letters were very popular in the period of Humanism and the Renaissance and their authors often grasped at the ancient role models. In the attempt to demonstrate the mutual interferences between the consolatory arguments from different periods, in this thesis is analysed content, language, and style of two consolatory letters, which the Sibenik humanist and Latinist Antun Vrancic (1504.-1573.) sent to two friends, with the intention to alleviate their grief over the death of their fathers. It is defined the structure of letters and also their linguistic and stylistic elements. It is examined the influence of ancient authors, as well as of two humanistic epistolographic manuals. At the end of the thesis is attached the own translation of letters from Latin into Croatian.
