Splitting word across lines

[nablator]

for instance, on the first line after the big capital, the word "cogitanti" is split without any markings.

Actually there is a tiny "=" there (you need to zoom to see it) and at the end of other lines where a hyphen is needed.

Hyphens are totally missing in some manuscripts, also in incunabula (or ~50% missing).

It's been pointed out in other threads that words were split without a hyphen between branches of plants in Italian herbals that have texts written close to the illustration much like the VM.
