I searched more about Pontanus, and there is strange ambiguity about his death date even on Czech websites. Some say 1614, some say 1616.
I had a closer look of the exlibris on You are not allowed to view links. Register or Login to view. (I reproduce the fragment from voynich.nu):
The last word does not look as "Tepence". The first letter looks like capital H, L or T (in all cases a strange one), the second one is like "i" if the first letter is H or L and like "p" with short descender otherwise, but by no means it is "e". The third letter is undoubtedly "x". Then there is a space, and then something like "pnize". The first letter after the space has a short descender to be a "p", but there's no better match, so must be a "p".
The presence of the letter "x" prevents all this from being read as "Tepence", at least verbatim.
