PT Journal AU Bockova, H TI Theatrum in older Czech literature. Reflecting the concept by Eduard Petru SO Bohemica Olomucensia PY 2019 BP 38 EP 50 VL 11 IS 3 DI 10.5507/bo.2019.031 DE theatrical metaphor; theatrum microcosmi; theatrum macrocosmi; Theatrum mundi minoris by Nathanael Vodnansky of Uracov; Theatrum divinum by Matous Konecny; Theatrum universitatis rerum by Jan Amos Komensky AB This study sums up the methodology of literary work by Eduard Petru in the field of early modern literature. It reflects his account of "theatrum" as a term, including its use in respective literature. First, its genesis since antiquity and early Christian beginnings is covered, together with the term's semantic scope modification during the Renaissance. Reflecting the spread of analogic thinking, the study traces Petru's concept of genre constitution based on "theatrical metaphor" which enables the depicted reality to be approached universally, be it the world as a whole or any of its parts. The author of the study ponders on Petru's characteristics of moralist texts based on semantics of "theatrum microcosmi" (i.e. Theatrum mundi minoris by Nathanael Vodnansky of Uracov) and encyclopaedic writings based on semantics of "theatrum macrocosmi" (i.e. Theatrum divinum by Matous Konecny, the plan of Theatrum universitatis rerum by Jan Amos Komensky).
