Treasured 15th Century World Map to Undergo Multispectral Imaging

The oldest and rarest manuscript map in the American Geographical Society Library’s collection–Venetian cartographer Giovanni Leardo’s 1452 mappamundi–will be scanned using multispectral technology in March this year.

A team from the Lazarus Project, based at the University of Rochester, is visiting AGSL to scan the Leardo and, via digital processing, produce archival-quality images that will reveal faded and even invisible-to-the-naked-eye inscriptions on the nearly 600 year-old hand-drawn map.

The Lazarus team will offer a talk on their project and the AGSL’s Leardo map on Wednesday, March 12 at 5 p.m. in the AGSL.
