The portolan was a nautical chart, handwritten or printed on a support in sheepskin or calfskin. “She combined three main elements: drawing, writing and measuring. That is to say an image, general or partial of the world, legends and instructions and finally measurable quantities. The map was constructed from a network of wind lines called rhumbs that radiated from compass roses. This canvas of lines served as the basis for the cartography.
The skin, which was often oriented with the animal's head to the left, was a support very sensitive to variations in humidity and temperature. A portolan will therefore never be completely flat.
