This volume presents the author's assertion that the fleets of Chinese Admiral Zheng visited the Americas prior to European explorer Christopher Columbus in 1492, and that this same Chinese fleet circumnavigated the globe a century before the expedition of Ferdinand Magellan. The author presents a series of vignettes describing his travels around the globe, examining what he claims is evidence for his "1421 hypothesis", interspersed with speculation and description of the achievements of Admiral Zheng's fleet. "A remarkable journey of discovery that rewrites our understanding of history"--Jacket.
