Herzog August Bibliothek.

This collection illuminates the intellectual and religious developments during the reigns of Ottheinrich (1556-1559) and Frederick III (1559-1576). It presents the complete works of the major Heidelberg figures (Bouquin, Erastus, Olevianus, Ursinus, Zanchi) and a major sampling of the works of many secondary figures. The collection represents the theological development of the Palatinate including the origins and reception of the Heidelberg Catechism, including attacks on the Palatine confession by Lutheran scholars.
