The key that unlocks a treasury of practical knowledge of the world we perceive and the mysteries hidden from view. Sibly's book represents the state of Western culture, scientific and occult, as of the end of the 18th century, including many astounding insights that are "forgotten knowledge" today. Sibly's scope includes medicine, healing, herbalism, astrology, horoscopes, mysticism, mesmerism, hypnosis, biology, botany and electrical therapy. His philosophy provides a comprehensive understanding of the universe based on earlier hermetic works brought up-to-date with Enlightenment era scientific discoveries. Copies of this book are nearly impossible to find. We obtained one over 40 years ago from an antiquarian bookseller and have meticulously preserved it in anticipation of creating this premium facsimile edition. Only in recent years has technology developed to the point where we can offer an affordable edition of this masterpiece in glorious full color. We have individually scanned every page and assembled them into this deluxe hardcover book which exactly duplicates our copy, including minor age spots and wrinkles. This is a book you will find compelling to read. Its importance is confirmed by the 2012 publication by Cambridge University Press in a black & white paperback edition. Ours is a beautiful hardcover full-color exact facsimile, the only color version now in print. It includes 13 full-page color illustrations, reproducing the hand-colored tints of the original engravings. You will be proud to own and to show this to your friends. It makes a splendid gift to the discerning collector. More than just a book, this is a profoundly beautiful object and a collector's item.
