"Comet literature is extensive but, to the best of my knowledge no previous work has quite the grasp of this one. There are some books dealing with restricted subjects that seem certain to become standard references for many years to come. This is one, and it should be in every serious scientific library."--Patrick Moore, The Times Higher Education Supplement "A work of serious scholarship that is rich in fascinating material... Judiciously selected quotations and fifty three illustrations, some exceptionally striking, add to the pleasure of reading this very engaging story, which is filled with surprises, ironies, and fresh insights."--Michael J. Crowe, Physics Today "Beautifully illustrated, full of fascinating quotations, and blessed with 126 pages of notes and references. I enjoyed it immensely."--David W. Hughes, Observatory "[This book] is accurate, comprehensive, and should make an important contribution to the history of astronomy."--Donald Yeomans, Sky & Telescope "This book is not a general history of comets... [T]he author is concerned primarily with the perception of comets throughout history. It is a scholarly well-illustrated and accurate work... [T]he author does a fine job."--Donald Yeomans, Nature "Every now and again a scholar comes along who successively maps out a novel idea, and does so in a compelling way. This well-written book is assuredly one such occasion and I recommend it to every scholar, no matter what their discipline."--Noel Grey, The European Legacy
