Should be Goethe, have read it in school ages ago. But its too long ago to write something useful about , have to read first again ...

Other possibility is it is a part of the history that led to the findings of the recipe of "Werthers Echte" ;-))))

And I am quite astonished again and again about your work and now as well about your education ..., much broader than usual, Goethe, language skills ...
