15. Bonn, (Bonna e Colonia) Presso N. Simrock , s.d. (1797), oblong in-4°, engraved title + 205 pp with engraved music. Plate number 42. Cont. red half roan, gilt title on smooth spine, binding with some wear at extremities, interior crisp and fine. Köchel Verzeichnis 527. See Köchel pp. 676. This is the first (oldest) complete keyboard transcription of the opera. It gives Lorenzo da Ponte's original Italian, with the German translation by Schröder underneath. The Hirsch collection (Hirsch IV 130) contains a similar but most probably later imprint of this edition with obviously a new title page with the title in German and with excerpts from Simrock's catalogue on the verso of page 205. In our copy this verso is blank. Schnapper (B.U.C.) Vol.II pp.702 describes also a copy with a blank p. 205 verso but with a title in German.
