Eybler wrote out the existing parts that Mozart had written out prior to his death, and did not go beyond the end of the ninth bar of the "Lacrimosa".
Die Schuldigkeit des ersten Gebots is regarded as a "sacred drama", Zaide, L'oca del Cairo and Lo sposo deluso are unfinished, with only uncompleted fragments making up the latter, and Der Stein der Weisen is a collaborative work.
