Diagnostics in late medieval sources

In this paper I focus on the nature of diagnosis in the Czech written medical sources. In the first part, the character of medieval medicine is described. Further, I deal with contemporary definitions of disease and some important aspects of diagnostic; finally, I adduce the signs of diseases described in examined sources: primarily the manuscript texts created in the first half of the 15th century and old printed books from the 16th century. I come to conclusion, that the medieval medicine was oriented on health problems instead of concrete diseases. For non-university trained physicians, the methods of healing were more important than quest to find the concrete disease.
