E. Gordon Duff, Early Printed Books
“ Hessels, and one that is hardly worthy of so learned a writer, is that since the Costeriana look older than the first Mainz books, therefore they are older. The foolishness of this reasoning is too apparent to need any explanation, for it amounts to the assertion that the same phase of development in different countries means the same date. But if the earliest dated books of the Low Countries are compared with the productions of Germany, it needs a prejudiced eye to see in the former any approach to the exquisite beauty and regularity of the German type and printing. ”
