Is the VMS homogeneous or a composite work?

[bi3mw]

It is not clear to me whether the VMS is a work that contains a coherent overall theme from the first to the last page and must therefore be considered homogeneous, or whether it is a matter of self-contained, separate chapters (sections) that were copied from different templates (from different authors). In the latter case the chapters (sections) would have nothing to do with each other. What do you think ?

There are, of course, recurring representations of certain illustrations, e.g. the naked nymphs, across sections, but that could also just be the interpretation of the illustrator of the VMS, suggesting a homogeneity that is not thematically present at all.
