HOW THE WOLRD GREW LARGER
Again I wish that I could make this book a thousand pages long. The subject of the early discoveries is so fascinating. But history, to give you a true idea of past times, should be like those etchings which Rembrandt used to make. It should cast a vivid light on certain important causes, on those which are best and greatest. All the rest should be left in the shadow or should be indicated by a few lines. And in this chapter I can only give you a short list of the most important discoveries.
