ENHighly popular Protestant postils were the first postillographic works in Europe. The names of their most eminent authors are widely known: Martin Luther, Philip Melanchthon, Anton Corvin, Johann Spangenberg. Postils served as a way to spread and define new teachings. Catholic postils were almost as popular as the Protestant collections. The rising popularity of Reformational postils brought about some significant reaction: from the 1520s, the number of German Catholic postils significantly increased and almost equalled Protestant postils in the number of titles and editions. The same tendencies of preaching art formation could be observed in Lithuania. The first Protestant postils written in Lithuanian emerged in Lithuania Minor at the end of the sixteenth century. At the beginning of the seventeenth century, the first Catholic postils appeared on the territory of the Grand Duchy of Lithuania (GDL) as a response towards Protestant postils and the ideas mentioned in them. In this study, an attempt will be made to present the first stage of the development of Lithuanian postillography, looking for analogies of this genre developed in other European countries, first of all in Poland and Germany, which affected the first Lithuanian preaching works. More attention will be paid to the first original postil written in Lithuanian and published in the early seventeenth century in Vilnius. [Extract, p. 245]
