In the manuscript collection of the Széchényi Library in Budapest there is a diary of the Hungarian humanist István Miskolci Csulyak. Hungarian researchers have known this source for a long time, and the Hungarist Richard Pražák introduced it to the Czech area. Miskolci's travelogue contains passages dedicated to his stay in Bohemia and especially in Prague. In the following article, they are presented in the form of a critical annotated edition.
