Аннотация:T he desire to investigate the personality of medieval rulers is a common aspiration in the study of political history.However, due to multiple methodological constraints, largely connected to the preservation and the nature of the available sources, this is a difficult, if not impossible, task.It may thus be useful to take advantage of two recent approaches that promise new perspectives and research possibilities.The first is the concept of a 'rulership style' (Herrschaftsstil), conceived 'as a variable set 'Mantuan Envoys at the Court of Sigismund of Luxembourg and Their Dispatches' , in Petr Elbel, Klara Hübner and Stanislav Bárta (eds), Der Hof Kaiser Sigismunds als personelle Bühne und internationales Zentrum (in press).
