Haci Ahmed's world map. This map, based on Oronce Fine's cordiform (heart-shaped) map of 1534, was translated into Turkish in the Islamic year 967 (October 1559 to September 1560). The author, Haci Ahmed is thought to be a pseudonym of the Venetian traveller Michele Membre and the interpreter Nicolo Cambi. The map may have been provided for Ottoman princes, as part of cultural and political exchanges between the two states. This copy was printed in 1795 from woodcut blocks found in the archives of the Council of Ten in Venice, Italy. The illustrations include two celestial hemispheres (lower left and lower right) and an armillary sphere (lower centre).
