Frederick felt ashamed to have a printing book in this library because he considered it as a inartistic source of information.
Step-by-step explanation:
- Duke Frederick is known to be a great manuscript dealer who constructed and maintained a magnificent library who was very famous at that times.
- The library is filled with various books that he had either largely purchased or collected by himself or books that he would have written on his own.
- In that library all the arts involved are perfectly beautiful and was written by skillful scribes.
- One of the interesting fact about that library is that I never had a single printed book in its collection.
- He would always consider printed books as trash and are designed by a mechanical work with inartistic feel and can only satisfy a group of uncultivated people.
Thus he always preferred manuscripts rather than printed books.
