The carta marina is the earliest detailed map of the Nordic countries. It took twelve years to finish and the first copies were printed in 1539 in Venice. Its existence had long been considered apocryphal, until a copy was discovered in Munich in 1886. The map is divided in 3×3 sheets with the dimension 55x40 cm (22x16 in), each made from a separate woodcut block. Historia de gentibus septentrionalibus (Rome, 1555) is a much larger commentary on the map.Map credit: Olaus Magnus
