Later this week, the Library of Congress will host a two-day conference celebrating the 500th anniversary of Martin Waldseemüller’s 1516 map, Carta Marina. Facts or Fictions: Debating the Mysteries of Early Modern Science and Cartography will take place on 6-7 October in the Coolidge Auditorium in the Library’s Thomas Jefferson Building in Washington, D.C. The conference agenda is not limited to Waldseemüller or his 1516 map; notable speakers include Kirsten Seaver, Chet Van Duzer and, with a major lecture, Dava Sobel. Free admission; no tickets or reservations required.

(The 1516 Carta Marina should not be confused with the Waldseemüller map most people mean: it’s his 1507 Universalis Cosmographia that names “America.” Nor should it be confused with Olaus Magnus’ Carta Marina.)
