"The Uffenbach brothers are visiting the shop of Tydeman in Zwolle, who brings them to his printing office. This room was full of beautiful paintings, Uffenbach's favorite was a small painting depicting the plundering and burning of houses by night. Uffenbach is impressed with Tydeman's collection of more than 14.000 prints by the best masters. He mentions a small, rectangular book with thirty or more seaviews painted in oil. Then they visit his library, consisting of mathematical books, especially about perspective."
