Portolan Map Possibilities

[-JKP-]

Too funny re Matthew Paris, i was just looking at one of his itineraries and he draws some cities like circular forts as well. Green salt water and blue tubes for rivers.

Yes! and Yes about the colors too.

And notice how the big waves are drawn in the top-left picture. That is how I usually interpret the "big waves" in the top-right rotum on the VMS "map". It looks to me like that is the side that probably faces the rougher water of the coastline (or major river).
