Title Henricus Martellus’s World Map at Yale
Chet Van Duzer discusses his new book on Henricus Martellus’ influential 1491 world map. Many texts on Martellus’ map are illegible due to fading and damage, making its exact place in Renaissance cartography impossible to determine. However, recent multispectral imaging of the map has rendered most of the previously illegible texts on the map legible. Van Duzer explained the process of multispectral imaging and how the results have enabled him to situate the Martellus map in late 15th- and early 16th-century cartography.
