Accurate maps help keep ships safe at sea. In the thirteenth, fourteenth and fifteenth centuries, maps called "portolan charts" recorded the accumulated experience and wisdom of generations of Mediterranean seafarers. Portolan charts were practical, no-nonsense tools made for the use of sailors who sailed "great waters."
These leggings feature a portolan map by Visconte Maggiolo (1478 – 1530). He was an Italian cartographer and sailor. He was born in Florence and was a fellow sailor of explorer Giovanni da Verrazzano. He died of malaria in 1530.
