This Library Treasures feature is part of NAASR’s 2022 focus on Armenian maps and cartography which has been supported by a grant from the Dadourian Foundation. Throughout the year we organized three lectures on this topic which can be viewed on our YouTube channel: Rouben Galichian, “The Ever-Changing Borders of Armenia in Ancient and Modern Times: The Cartographic Record”; Matthew Karanian, “Mapping the Armenian Highland”; and Khatchig Mouradian, “Gas Balloons, Emperors, and Armenian Mapmakers: A Cartographic Journey through the Library of Congress’s Collections.”
