Pretty medieval manuscript of the day is another ship. This line drawing is quite different to many of the other illustrations we’ve looked at. There’s movement in the sails, and a sense of perspective which is lacking in many other manuscripts. I don’t know the context of the drawing - whether it is an original piece of art, or an extreme example of marginalia. The facing page is painted and illuminated in an entirely different style.
The book dates from the fifteenth century and is by Gregorio Dati.
