This book is remarkable for its breadth and depth, and for its fluid and totally enjoyable narrative. Montgomery brings a scholarly, well-organized, imaginatively catholic mind to his study of the moon, as mapped, observed, and imagined by Western minds. His enthusiasm for his subject is contagious. He discusses the early cartography so important to popular conceptions of the moon, the moon's complex and changing relationship to Christianity and Judaism, philosophy, mathematics, literature, and art. Importantly, he provides an orderly and very interesting history of Western conceptions of "the first modern planet." The Arab contribution to astronomy is detailed. The relationship of mathematics to astronomy is also explored, fluidly and appropriately for the lay person. Galileo, Copernicus, and scores of lesser-known astronomers and scientists come to life in this book. "The British Contribution," a chapter on sixteenth century lunar pioneers Dr. Wm. Gilbert and Thomas Harriot, is excellent. Montgomery also analyzes cartographic evidence - and provides commentary. This book combines scholarship with a fine and elegant narrative, the bibliography is terrific, and I would recommend it to anyone with an interest in this subject, which becomes downright thrilling in this book.
