Martellus Project: Multispectral imaging used to reveal map’s secrets

Martellus Project: Multispectral imaging used to reveal map’s secrets

  • 15.08.2014

This week at the Beinecke Rare Book and Manuscript Library, from August 11-19, an interdisciplinary team is at work on a multispectral imaging project to facilitate the study of a 15th century world map by cartographer Henricus Martellus. The map likely influenced Christopher Columbus and is representative of his geographical views.

The map, which is typically on display to the left of the Beinecke’s service desk, has been relatively unexamined following a peak in interest after its acquisition in the 1960s because it is largely illegible. Efforts to image the map in the ‘60s using UV light revealed that the text could be recovered through such techniques, though it was not until the past decade that technology developed that could reveal all of its secrets.

A team of researchers are using multispectral imaging to uncover hidden text on a 1491 Martellus map, one of the most important maps in history. Lead researcher Chet Van Duzer thinks the discoveries will allow historians and scholars to see just how the map influenced cartography in its time.
