Friends with an old book, Martino Galli
The book “V columnae”, written by Hans Blum, is physically available at the Zentralbibliothek Zürich (Zähringerplatz 6, 8001 Zurich) and at the ETH-Bibliothek Zürich. In both cases it is not the first edition of the book, since the available copies were printed in 1596 and the first edition of the book dates back to 1550.
Fortunately, this book can also be consulted in digital format in databases such as ETH e-rara (https://www.e-rara.ch/zut/content/titleinfo/1611039) and google books (https://books.google.ch/books?id=Tf9PAAAAcAAJ&pg=PP37&dq=V+columnae&hl=it&sa=X&ved=2ahUKEwjLveqB96zsAhWtlYsKHWdaDmAQ6AEwAXoECAEQAg#v=onepage&q=V%20columnae&f=false).
