Cartography enthusiasts will want to delve into Maps That Changed Our World: an Esri Story Map created by Julie Stoner, Rodney Hardy, and Craig Bryant of the Library of Congress Geography and Map Division. This story map is a digital interactive project that highlights a handful of fascinating maps created over the past several centuries. Maps that Changed Our World starts by introducing visitors to Claudius Ptolemy who, in his 150 CE textbook Geography, detailed the world as he knew it using mathematics and knowledge of early civilizations. In 1482, Jacopo d'Angelo and Nicolaus Germanus created a physical map that represented Ptolemy's text, which visitors can view in this story map. Other featured maps include Muhammad Ibn al-Idrisi's 1157 map of the world as compiled in 1928 by Konrad Miller; the 1457 Genoese world map; Gerardus Mercator's 1569 map; and much more.
