Before the turn of the 19th century, ventures into uncharted lands required material or spiritual reward to justify the perils of shipwreck and hostile natives and dangers yet unknown. Until recent times exploration for the sake of knowledge alone was rare and mostly undertaken by intrepid traders, gold seekers and valiant Christian missionaries. In this book the author selects more than 150 of those he considers to be the most influential and unusual journeys of discovery, setting each firmly in its historical context. This book chronicles the personalities and motivations, the conditions that had to be endured and the contribution that exploration has made to our knowledge of the world. It is replete with extraordinary personalities: the heroic adventurers who set out into the unknown, battling against the elements in order to commit their findings to journals and maps.
