John Hessler Will Discuss Martin Waldseemüller’s 1513 Map of the Upper Rhine Valley

As a prelude to "Exploring Waldseemüller’s World," an international symposium at the Library of Congress on May 14 and 15, John Hessler will discuss one of Martin Waldseemüller’s other cartographic creations – the 1513 Map of the Upper Rhine.

Hessler, a senior reference librarian in the Library’s Geography and Map Division and a fellow of the Royal Geographical Society, will present "Surveying the Renaissance: Martin Waldseemüller’s 1513 Map of the Upper Rhine Valley" at noon on Wednesday, May 6, in the Geography and Map Division Reading Room on the basement level of the James Madison Building, 101 Independence Ave. S.E., Washington, D.C.

Sponsored by the Library’s Geography and Map Division, the event is free and open to the public; no tickets or reservations are needed. The lecture is part of an ongoing series called "Map Talk."

For more than a century, it has been thought that Waldseemüller himself surveyed the region portrayed in the 1513 Map of the Upper Rhine. But recent research by Hessler has cast doubts on this accepted notion.

"By showing that Waldseemüller actually copied several texts on surveying from 13th-century sources and then claimed authorship for them, I call into question many of Waldseemüller’s claims regarding his large scale map of the Rhine Valley," said Hessler.

In addition, Hessler will discuss Waldseemüller’s 1513 edition of Ptolemy’s "Geographia," in which the Rhine Map is found, and the origin of the medieval manuscript fragments found in the binding of the Geography and Map Division’s copy.

On May 14 and May 15, prominent scholars will gather at the Library of Congress to examine Martin Waldseemüller’s cartographic vision and to reflect on the philosophical and historical context of the production and reception of his famous 1507 World Map. The symposium, which runs from 9:30 a.m. to 7:30 p.m. on Thursday, May 14, and from 9:30 a.m. to 5:30 p.m. on Friday, May 15, will be held in the Coolidge Auditorium on the ground level of the Thomas Jefferson Building, 10 First St. S.E., Washington, D.C.
