Tells the story of how Chinese, Japanese, Korean, and Persian explorers mapped ancient America's West Coast. Marco PoloÕs daughters were among the women who altered the course of history. The book reveals the story behind their incredible ÒAdventure Travel Shows.Ó Marco Polo was much more than just a traveling journalist who went to China in the 13th century. He was first-and-foremost a technological spy. Marco Polo's voyages covered coastal regions along the Northwest Passage of Canada and down the West Coast from Alaska to Peru. These were presented to the Italian womenÕs salons of the early Renaissance, where they played a significant role in the literacy and scientific training of young women. Marco Polo started the Northwest Passage Legend; and he brought the first firearms (the harquebus) back to Europe from China.
