Earthsickness: Circumnavigation and the Terrestrial Human Body, 1520-1800.

From their distinctive experience of going around the world, maritime circumnavigators concluded that their characteristic disease, sea scurvy, must result from their being away from land too long, much longer than any other sailors. They offered their scorbutic bodies as proof that humans were terrestrial creatures, physically suited to the earthly parts of a terraqueous globe. That arresting claim is at odds with the current literature on the cultural implications of European expansion, which has emphasized early modern colonists' and travelers' fear of alien places, and has concluded that they had a small and restricted geographic imagination that fell short of the planetary consciousness associated with the nineteenth and twentieth centuries. But circumnavigators did conceive of themselves as actors on a planetary scale, as creatures adapted to all of the land on Earth, not just their places of origin. [ABSTRACT FROM AUTHOR]
