The translation from Latin and Czech into Polish of an entire important, but still little-known work (Latin Dedicatio ad tria regna – Czech Dedikace třem královstvím – English Dedication to the three Kingdoms) introduces us to a large extent to the subject matter of the “i m p r o v e m e n t o f human affairs”. The translation of this manuscript fills a large gap in Polish comeniology. In the work translated into Polish, we can see how John Amos Comenius persistently and decisively pursued the honorable goal he had set for himself – that is, the pansophic improvement of all human affairs. The Polish-speaking reader will finally be able to “fully” read this work in their native language, in which there are also important elements related not only to pedagogical and educational topics, but above all to socio-philosophical issues and theological-biblical comparative references, centered around the domain of interdisciplinary research. The so-called “Portrait sketch” is also presented, or what hopes Comenius linked to the three described countries, strictly speaking the kingdoms of the North, i.e. Poland, Sweden and Great Britain, during the period of significant changes in seventeenth-century Europe.
