Mystery, money and dubious dealings: The story of the Vinland map has it all. Author Kirsten Seaver will share the tale next week at California State University, Stanislaus.

What: Discovered in 1957, the Vinland map was originally thought to be a medieval chart of Norse explorations of the world. The excitement surrounding its discovery proved lucrative for some. Within a few years, however, skepticism mounted as to the map’s authenticity.

While historians and scientists continue to challenge the Vinland map’s historic value, a strong contingent defends its validity.

Where: Carol Burke Lounge, CSU Stanislaus campus, One University Circle, Turlock

Who: Kirsten Seaver, a fellow of the Royal Geographic Society, London and author of “Maps, Myth and Men: The Story of the Vinland Map”
