The memory of the Reformation was the identity of the Protestant denominations in the early modern period. The memoria was, as it were, the arch of remembrance that connected the Lutheran, but also the Reformed denomination with its beginnings. Different forms of expression of memory are exemplarily analyzed, contextually interpreted and profiled in an interdisciplinary manner by recognized scientists. This enables a new construction of the history of the Reformation culture of remembrance from the 16th to the 18th century, which is particularly vivid in the early modern Lutheran territories of the Ernestine dukes.
