I myself don't own any old books, neither do my parents; but my granpda has a medicine and biology book from the 17th or 18th century... I'll have to look up the exact date when I'm at his house, but if my memory serves me right, it was 16xx....
It's really an old book, and describes a few illnesses on the human body and how to combat them; using all the latin terms for the illnesses and so on - which is particulary funny, as they used the Gothic "alphabet" / font-style for the German text and the "normal" font for the bits and pieces in Latin... So you have a text full of the Gothic font, and then, every two or three lines, a normal word like "canceris" or whatever... It is really funny
