Medieval geography


I have just uploaded a new chapter of my study about the revival of geographical knowledge in medieval Europe. It can be viewed at
Together with the previously uploaded parts
these four articles cover Unit I of my second project. The Unit’s title is “The Miraculous Revival or the Painful Recovery”. It is devoted to diverse aspects of mathematical geography as they were discovered by medieval scholars including the prospects of navigation through the world ocean.
I would be very grateful to have your comments.
