The nautical dimension of prehistory has not so far received the attention it deserves. It is also too often assumed that early man was land bound, yet this is demonstrably not the case. Recent research has shown that man travelled and tracked over greater distances and at a much earlier date than has previously been thought possible. Some of these facts can be explained only by man's mastery of water transport from earliest times. This book, by an acknowledged expert on prehistoric sea-craft, examines these problems looking at the new archaeological information in the light of the author's nautical knowledge. The result is a detailed account of man's use of inland and ocean-going craft from earliest times until the dawn of recorded history. All forms of evidence are critically assessed, from the vessels of Ancient Egypt to the Chinese junk, to present of comprehensive picture of the vessels men have built through the ages, and of the variety of ways in which they have been used.
