I attended a medieval festival in my tiny ass Italian town, and for some reason David Tennant was there. Turns out he's practically my neighbour. I went to his daughter to ask whether or not it was him and then proceeded to say that I respect their private life, and left them alone without even asking for a picture.
Today's manuscript is LJS 473, a 15th century Italian treatise on ships and shipbuilding. It includes information on cartography, construction and use of the compass, types of ships, and meteorology and astronomy for use in navigation, and has two maps of the earth - one of the earth and the spheres surrounding it (representing the sky and the Zodiac), and the other that divides the earth into temperate zones (hotter around the middle and colder on the ends).
