Portolan Map Possibilities

LOL!

Linda, I was just going to post a link to the Michael of Rhodes example, and then I decided to read the thread before posting and there it is.

 Oh, and I keep forgetting to post that Matthew Paris is significant in the 13th century because it includes not only the itinerary, maps, and winds, but also numeric tables (for calculating Easter) and calendars. In other words, like a "handbook" for travel

Michael of Rhodes had a Table of Solomon which gave him the new moon for almost a hundred years worth and also did the Easter thing. Also sun and moon tables but he copied them incorrectly. Also a zodiac man, you were not to bloodlet when the moon tides affected the blood, so there is medical too. Also shipbuilding info, and notes on all his excursions. I added a link to that post to the website, i like it because it is contemporary to the time of our manuscript and gives glimpses into how people thought at the time.

The sun and moon tables look like the crisscross table in the catalan atlas, ill bet its the original and he got it third or fourth hand, which is why the mistakes.


The one at the bottom, zodiac names criss crossed.

Better pic/version



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.
