Lehigh Codex 12 Anon. Portolan charts

Three maritime charts bound in contemporary parchment over paper board. The first chart shows the 26th to the 51st northern gradations, the coasts of England and Ireland south to Madeira and the Canary Islands, including the coasts of Spain and France. The second chart shows the whole of the Mediterranean, including the coasts of the eastern Mediterranean and Northern Africa. The third chart shows the Mediterranean from the Meridian of Gallipoli (Italy) to Dakar, Africa, including part of the Atlantic Ocean and the coasts of Spain and Portugal. All have rhumb lines, and were used for navigation. Although written in Italy, the place names on the manuscript show Portuguese influence.
