Joseph Nigg. Sea Monsters: A Voyage around the World's Most Beguiling Map.
Chicago & London, 2013. Cloth. Out of print.
A delightful study of Olaus Magnus' 1539 'Carta Marina,' which charted the sea-serpents, giant man-eating lobsters and other monsters thought to swim in northern waters, threatening 16th century seafarers who sailed too far from shore.
