This book presents a selection of ocean-going charts dating from the 13th century to the 17th century. Rudimentary they may perforce be, but they bear excellent witness to the achievements of the early European navigators, and to their determination to explore the ends of the Earth. What the charts may lack in geographical accuracy, they undoubtedly make up for in their charm. And of course they are invaluable as historical records. Recounting the epic journeys of maritim exploration, from Erik the Red to Robert Peary, author Donald Wigal leads us gently and pleasurably from Terra Incognita to the World As We Know It.
