Book excerpt: "Going round the world" is an idea that has excited people ever since it was realized that the earth was a sphere. The appeal has something to do with encompassing all the known environment and exploring the unknown, not only on the surface of the planet but within the spirit of the explorer. The story of circumnavigation is thus a long saga of human adventure, travel and discovery. Beginning with the fateful day in 1521 when Ferdinand Magellan was speared to death on Mactan and Juan de Elcano took up the challenge of bringing his surviving companions home, the story continues through four centuries crammed with astonishing exploits by men and women of many nations. Some of the names that feature are well-known, others less so.
