This thread's posts for 16 and 17 April, some of the posts anyway, can be confusing. A word of clarification might help.

The comments about "Frühlingsmusikanten," with the tragically assassinated dramatist/poet Kotzebue pulled in: that's all my fault.
Grishka is entirely correct here:   there is a satirical conceit
at work, in which a different writer impersonates Kotzebue
"aus der Unterwelt," from the underworld, literally.

I was so tickled when books dot google dot com pulled up
what appeared to be a contemporary criticism of Friedrich Förster's satirical poem,
that I rushed to post it here.
And totally messed up in doing it, because it is satirical
and parodying on multiple levels, and I missed most of it.

The fellow who wrote,
pretending to be Kotzebue in the afterlife,
was actually a journalist critic named Adolf Müllner,
who wrote scathing criticism
and specialized in sensational "Schicksal"-dramas.
Müllner knew Kotzebue personally, so he had some investment emotionally
in pretending to be an author whom even death could not silence.
Oh what times he lived in.
