Originally composed in 932 AH / 1525 CE and dedicated to Sultan Süleyman I (the Magnificent), this great work by Piri Reis (d. 962 AH / 1555 CE) on navigation was later revised and expanded. The present manuscript, made mostly in the late eleventh century AH / seventeenth CE, is based on the later expanded version and has some 240 exquisitely executed maps and portolan charts. They include a world map with the outline of the Americas (fol. 41a) and maps of coastlines (bays, capes, peninsulas); islands; mountains; and cities of the Mediterranean basin and the Black Sea.
