This engaging book, using over forty magnificent color reproductions of antique and new maps, and written in clear, lively prose, shows how maps have evolved over centuries, beginning with a Babylonian etching on a clay tablet and ending with a radar image taken from the space shuttle Endeavor. Young geographers - and readers of all ages - will be riveted by the adventures of real-life explorers, scientists, and mapmakers, including Ptolemy, Cheng Ho, Columbus, and the many modern cartographers.
