A call to the German Imperial Diet to assure civil and religious accord, arising out of the threat of the Turkish menace. Through this open appeal the author seeks to persuade the participants in the Imperial Diet meeting at Regensburg to discuss the options for assuring civil and religious accord in the land. Only an internally united and well-run state will have the strength to withstand a gathering danger from without - Turkish expansionism. He considers the uncertain situation in contemporary Germany and supports his arguments with the words of the Old Testament prophet Jeremiah, not uncommonly with the declarations of Luther regarding the Turkish menace, and also with two new prophecies by Meliš on the future of European nations (cf. Štěpán Meliš).
While Comenius’ authorship is contentious, the construction and style of the treatise are clearly in his favour.
