Abstract
This presentation explores the possibilities of visual representation of medieval sermons. Sermons were a marginal literary genre that was widespread in the Middle Ages, and many individual sermon records have survived.
The visualisation of sermons can refer not only to their content but also to their various features. In this way, it is possible to identify different groups among sermons and to show which values from different categories are correlated.
The case study deals with the medieval sermons of the Czech Utraquists on the feasts of the Czech patron saints. It presents different ways of visualising them, such as network graphs, Sankey diagrams, or correspondence analysis visualisation.
It also discusses which tools (packages) can be used for these purposes in the programming languages R and Python, and what are the advantages and disadvantages of each solution.
