Explorers of the Late Renaissance and the Enlightenment [PDF ebook] 

As the Age of Exploration came to a close, the world seemed to be a significantly smaller place than it once was, with more major landmasses identified on the global map. Yet questions and unknowns remained and details had yet to be filled in. Armed with greater knowledge and better equipment than their predecessors, explorers in the late Renaissance and Enlightenment eras took up the reins, with some discovering new routes and lands still while others carefully surveyed or settled lands already known. This lively volume details the lives of such individuals as Henry Hudson, Vitus Bering, James Cook, and Daniel Boone, among many others, as well as the explorations and discoveries of which they were a part.
