Description: This book is a story of the progress of the science of navigation from earliest times to the present. Today’s navigator can fix his position and plot his course to his destination with great accuracy. But this result has been achieved only after long centuries of ceaseless struggle.
The search for navigational knowledge began thousands of years before the Christian era. The heroes of this dramatic story are colorful: princes and philosophers; glaziers and clock makers; Scottish lairds and French admirals; Polynesian canoe paddlers and scholars from Alexandria. Yet they were alike in their tireless devotion to the problem on whose successful solution our whole civilization depended.
Mr. Calahan, a lieutenant commander in the Naval Reserve, is well known as the author of the most widely read books on small boat sailing. He bases his evaluation of historic discoveries and inventions on his own experience as a navigator. Always careful to present the accepted view of events, he does not hesitate to add his own sometimes startling conclusions.
In his extensive research, Mr. Calahan has in most instances dug down to original sources. But there is a breath of salt sea air in his swift-flowing style (“free-wheeling,” one critic has called it). While this is the history of a science, it is men who have made the science, and there is drama in the story of their discoveries. Throughout this book there pulses a sense of great devotion, the age-long struggle to utilize the beacons in the sky.
