Notable Quotes

 * Since the first light dawned eight months ago, since broad daylight came three months ago, and since the sun of my wonderful discovery shone fully only a very few days ago, nothing holds me back ... The die is cast, and I am writing the book -- whether to be read by my contemporaries or by posterity matters not. It may be that my book will wait a hundred years for a reader; but has not God waited six thousand years for a proper observer of His handiwork?
 * -- from the Preface

Critical View

 * A few pages of great science and an overwhelming, luxuriant growth of mystical fantasy.
