Dubno and N. H. Wessely (cf. JubA Band 15,1), moreover philosophical commentaries, letters, a poem and documents of the Jewish community in Berlin. The annotated transcription of the list of subscribers reveals a document which is important for the reception history of the Pentateuch edition. Apart from the commentary on Ecclesiastes and the pamphlet on the Pentateuch edition, which are published in contemporary translations by Johann Jacob Rabe and Christian Gottlob Meyer, this volume provides access to Mendelssohn’s texts in a new and for the first time complete translation.
