"This book covers all the major developments in navigation adequately, and in a manner easily accessible to the general public. It is not the result of new research or insight, and does not have that pretention. I recommend it to those with an interest in the history of navigation, and it will be an excellent starting-point for those wanting to pursue the subject further." -- W.F.J. Mörzer Bruyns, The International Journal of Maritime History

"A masterly and comprehensive survey of navigational techniques across many centuries of technical skill and astute practical innovation. The book combines lucid exposition of the principal maritime methods with fascinating commentary on the historical relation between navigators' mastery of calculation, observation and improvisation." - Simon Schaffer, University of Cambridge
