FIRST EDITION. COMPLETE WITH THE RARE SECOND LEAF with ten-line defense of the Catholic Church on verso. The present work comprises a series of attacks against the Bohemian Brethren (also known as the Unitas Fratrum), who emerged during the Bohemian Reformation in the late 15th century. Jacob Zeigler, a Catholic mathematician and theologian from Bavaria, was among their fiercest critics. RARE: we trace only one other copy appearing on the market: "The book is also one of the earliest Leipzig imprints in Roman type. It is VERY RARE on the market, especially if complete with the second leaf, which is blank except for ten lines" (Lathrop Harper, catalogue note). Apponyi, Hungarica I, 86; Hanslik, Geschichte und Beschreibung der Prager Universitätsbibliothek (1851), 561; Panzer VII, 175, 372; Proctor 11351.
