"Portulans" are medieval nautical maps, provided with a wealth of geographical coastal names and conceived for being used by seafarers. Because they used to be frequently rolled up and constantly consulted aboard, the surviving “carte da navigar” are extremely rare and not always in good condition.
Portulan C.G.A.5.b (Majorca, 1450-1460 ca.), 61 × 90 cm, shows the Mediterranean basin and the Atlantic Ocean from Norway to Morocco. Less decorated than the previous one, it was likely a real “carta da navigar” to be used onboard by seamen. The cities of Barcelona, Valencia, Santiago de Compostela, Granada, Venice, and Genua are singled out. The map features many human symbols such as flags, shields, and towns, and a few natural elements.
