Maps by Piri Reis
Piri Reis (Hacı Ahmed Muhiddin Piri Reis) was an Ottoman sea captain (Kapudan-i Derya), geographer and cartographer who lived between 1465 or 1470, and 1554 or 1555. His maps and charts are collected in the Book of Navigation (Kitab-ı Bahriye), which contains detailed information on navigation, as well as very accurate charts detailing important ports and cities of the Mediterranean.
