Alchemical Symbolism in the VMS

[MarcoP]

Hi Matthias,
I haven't read the text, but I think they are not literal "flowers". Here "flower" means "the best part of something".
Similar  titles are "flores sapientiae" (the flowers of wisdom), "flores eloquentiae" (the flowers of eloquence), You are not allowed to view links. Register or Login to view. (the flowers of history). 

EDIT: "Flores Secretorum de regimine quatuor naturarum" means something like "the best secrets about the properties of the four humors".
