So far the history of medieval Franciscan Observance has been considered as the history of individual monasteries, or more generally as the history of disputes concerning education, culture and nationality. The aim of the present dissertation is to describe the history in terms of cultural history, to analyze wider issues of architecture regarding monastic buildings of the last big monastic community of The Middle Ages, to describe them and evaluate. The basic structure of the dissertation consists of monographic chapters monitoring the history and building development of fifteen preserved and thirteen extinct monasteries in territory of the Czech monastic province (Bohemia, Moravia, Silesia and Upper Lusatia). The catalogue part is introduced by chapters summarizing the historical context of Franciscan Observants' activities within a short period between the second half of the 15th century and the first half of the 16th century, during which the Observants of the Czech province experienced both the stage of raise and decay. The history of the order is then followed by an essay on the rules of the process of foundation constructions of the convents, the order rules limiting artwork and mainly the character of the order architecture.

Cette thèse porte sur la carrière musicale de Joseph Kohaut (1734–1777), l’un des derniers luthistes dans l’Europe des Lumières. Appartenant à la deuxième génération des musiciens originaires des pays de la couronne de Bohême, ce luthiste, né à Vienne et décédé à Paris, représente un cas intéressant de la migration des musiciens au XVIIIe siècle. L’étude se consacre à la présentation des origines et de la famille proche du musicien (son père Jacob Joseph Kohaut et son frère aîné Karl Kohaut), ainsi qu’à la carrière musicale du luthiste proprement dite. Le patronage aristocratique s’y révèle le moteur principal aussi pour son œuvre, y compris ses opéras comiques qui contribuèrent à la notoriété de Kohaut également en déhors de la France. Enfin, cette étude traite les œuvres des deux frères Kohaut en s’intéressant aux attributions douteuses et propose un catalogue thématique du corpus entier indexant toutes les sources connues. / This thesis focuses on the musical career of Joseph Kohaut (1734–1777), one of the last known lute players in Europe of the Enlightenment. Belonging to the second generation of the musicians originated from the Czech lands, this lutenist, born in Vienna and dead in Paris, represents an interesting case of the migration of musicians in the 18th century Europe. After having examinated the origines of the musician and his close family (his father Jacob Joseph Kohaut and his older brother Karl Kohaut), the study analyses his own musical career. The aristocratic patronage becomes apparent as an important reason for his musical production, including his comic operas that made him famous also outside France. Finally, this study addresses the compositions of both brothers Kohaut, taking interest in problematic attributions, and offers a thematic catalogue of all works registering their all known sources.
