Moribund the Burgermeister

Was there a ‘Moribund the Burgermeister’ before Peter Gabriel’s song? i.e., was there a folk tale about such a figure?

Here is what Song Facts has to say:

I have no idea how accurate that is.

Was there a character named Moribund the Burgermeister associated with this disease? (i.e., before Gabriel mentioned the name in his song?)

Here is a blog which discusses the meaning of this song.

None of the contributors mention a real Moribund the Burgermeister. There’s a pretty strong argument for the lyric telling a story about the plague.
