With a focus on the navigational tools invented by each age and civilization, Launer traces the evolution of humankind's navigational skills from the Kamal of the Arabs and the Lead-line first used by the Romans to the radio and satellite communication devices available to modern sailors. He pays homage to the Polynesians who, in the absence of a written language were able to pass down their navigational skills through generations, and to the adventurous Vikings, who managed to find their way from Scandinavia to England, Iceland, Greenland and beyond; but he also covers the practical applications of the complex technologies found on most boats today, such as GPS. Generous illustrations help readers envision the tools in use.

Navigation Through the Ages will appeal to sailors and lay readers alikeanyone with an interest in the history of science and the exploration of our world.
