Query: Good book

This book helped me to understand a lot of the false mythology that grew up around the discovery of the New World by Columbus. Many of these myths Professor Simek shows were totally untrue, and not accepted by the Medieval world. Such myths are; the flatness of the earth, the theological condemnation of Columbus's journey as immaterial, and the idea that the earth did not rotate on its axis.In addition, Simek also provides much information by both Greek and Latin authors as to how they solved peculiar cosmological problems which they viewed when studying the night sky.I found this book to be informative, short, easy to read and understand, with many pictures depicting physical explanations of problems, and also very interesting. I would definitely recommmend this book to be readby both students of history and astronomy.
