Readers of history will delight in Fernández-Armesto's latest. The Tufts historian (Millennium
) deftly manages the near-impossible task of a comprehensive account of world exploration from the dawn of humankind while maintaining an interesting tone throughout. The evocatively titled chapters ("Reaching," "Stirring," "Springing") follow a well-organized outline, and short sections keep the reader from feeling overwhelmed with information. Beginning with Homo erectus
's migrations from East Africa to the rest of the continent and to Eurasia a million and a half years ago, the book examines how and why cultures spread throughout the world. Each section of the globe is examined, from the Tigris and Euphrates to the Pacific Islands, the Middle East and Africa. Along the way, technological and scientific leaps, such as sails, cartography and the cure for scurvy are explained. Fernández-Armesto also looks at the important role economics and politics have played in world exploration, The author excels when he narrows the focus, such as when he places Columbus into historical context so that the magnitude of his journey and its difficulty are fully felt. This volume truly covers everything the title claims, resulting in a rich history of our world. 16 pages of color illus., 44 b&w illus., 48 maps. (Oct.)
