Query: A unique book on a fascinating subject

This book tells the stories of a number of great explorers of the ancient world, both East and West. Included are the stories of Hanno, a Phoenician who sailed along the Atlantic coast of Africa in 500 BC, Nehsi, an Egyptian nobleman who led an expedition to Punt in ancient Somalia in 1500 BC, Pytheas, a Greek who sailed to Britain and perhaps Iceland in 330 BC, and many others.The book is well written, being both interesting and informative. Excellent pictures and graphics add to the overall quality of the book. If I have one complaint against the book it is that I did notice several minor inaccuracies. However, as this book is not intended as a textbook, these problems can be overlooked.Though published as a "juvenile" book, I would recommend it to readers of any age.
