Joseph von Eichendorff's (1788-1857) diaries are of major importance for the cultural history of the late 18th and early 19th centuries. They cast light on economic, medical, and religious aspects of life at the time, on important loci of socialization and education, such as school, university, and the theatre, and also reflect political activities and modes of travel typical of the age. Both in the text and the commentary, the historical-critical edition has made substantial revisions to all previous printed versions of the diaries.
