Saturday, May 6, 2:00 pm: Chet Van Duzer on “New Light on
Henricus Martellus’s World Map (c. 1491) at Yale: Multispectral
Imaging and Early Renaissance Cartography”
Avenues: The World School, 17th Floor, 11 East 26th St. (between
Fifth & Madison), New York City
"I will give an account of a recent project funded by the National
Endowment for the Humanities to make multispectral images of a
world map made by Henricus Martellus in about 1491, held by the
Beinecke Library at Yale. This large map, one of the most important  
of the fifteenth century, was thought to have influenced Martin
Waldseemüller’s world map of 1507, but the many texts on the map
were illegible due to fading and damage, and thus its exact place in
Renaissance cartography was impossible to determine. The new
multispectral images have rendered most of the previously illegible
texts on the map legible. I will explain why the Martellus map was an
excellent candidate for multispectral imaging, describe the process of
making the images, show the results, and give an account of the
place of the Martellus map in late fifteenth- and early sixteenth-
century cartography."
Chet Van Duzer is a member of the New York Map Society, a cartographic
historian and the author of numerous articles and five books, the most recent
"Sea Monsters on Medieval and Renaissance Maps."I study medieval and
Renaissance maps -- mappaemundi, nautical charts, and the maps in
Ptolemy's Geography -- with an emphasis on determining the sources that
cartographers used for the   texts, images, and geographical features on
maps. One part of my work has been to study damaged map by recovering
information from them using multispectral imaging. I am a Board Member of
the Lazarus Project at the University of Mississippi, which provides low-cost
access to multispectral imaging to institutions and researchers around the
world. See
