This map of Iceland was made by Abraham Ortelius, a mapmaker from the late 1500s. He was not an explorer or a scientist, so he used another mapmakers' information about sea monsters in order to make his map of Iceland. One of these mapmakers, Olaus Magnus was a man from Sweden who moved to Rome several decades before Abraham began making maps. Olaus wrote a book about Scandinavia, the region around Sweden, and described many of the sea monsters that Swedish people believed in.
