Benjamin Franklin DeCosta's "Inventio Fortunata: Arctic Exploration, With An Account Of Nicholas Of Lynn" (originally presented to the American Geographical Society in 1880) investigates the legendary 14th-century account of Arctic exploration. It discusses the mysterious Inventio Fortunata document and the voyage of Franciscan friar Nicholas of Lynn to the North Pole. The Inventio Fortunata: DeCosta analyzes this lost book (translated as "Lucky Discovery" or "Fortune's Invention"), which was allegedly written by a Nicholas of Lynn and later used by mapmakers like Mercator to describe the North Pole as a sea surrounding a magnetic mountain. Arctic Exploration Focus: The paper examines early European efforts to map the far North and understand northern geography.
