The article presents a manuscript collection of texts of evangelical provenance that has recently been purchased in a German second-hand bookshop. According to a chronogram, this manuscript is likely to come from 1840. The manuscript consists of fifteen relatively independent text sections thematically related to the denominational controversies before and after the battle of White Mountain. The paper examines possible printed or manuscript
models of individual parts and as well as their reflection in both earlier and more recent bibliographic literature.
The article presents two likely and so far unknown compilers of the third edition of Koniáš’s Key from 1770. Their names have been revealed by a handwritten note in a copy that was originally a part of the library of the private collector Josef Bartsch (1731–1803). Concerning the first figure, the Jesuit Josef Kögler, the treatise describes his career in the Jesuit Order and the posts that he held. In the case of his co-worker Jan Kohout, the text outlines the possible connections that might help identify him precisely.
