Archaeologists have always insisted that ancient lenses never existed. Temple's detective work began when he discovered an artefact in the British Museum, believed to be plain rock crystal. He discovered it had been ground to form a lens and proved the true age of optical surveying techniques.

Amazon Review
Lying unnoticed in many museums around the world are large numbers of ancient artefacts fashioned out of rock crystal or glass; lenticular in shape, they are habitually described by archaeologists and cataloguers as decorative in purpose; in short, as costume jewellery. To Robert Temple, however, who bolsters his classical and linguistic erudition with expertise in the field of optics, they are obviously and self-evidently lenses. As such, they form the starting point for The Crystal Sun, his wide-ranging and provocative investigation into the existence of an ancient science of optics. There is much to amaze here, not least the sheer volume of evidence that Temple is able to amass (and the seemingly even greater volume to which, for various tiresome reasons, he was unable to gain access). It is this density of proof, and the hardness of the science involved, that tend to dispel suspicions that we are entering Jesus-was-an-astronaut territory.
The narrative of Temple's discoveries is cast almost as an intellectual detective novel. (A characteristic recurring motif is his exasperation with the small-mindedness and intellectual prejudice endemic in the archaeological profession.) From the physical lenses we move to the scattered descriptions of lenses, telescopes and their use by the Greeks and Romans, the destructive use of burning-mirrors by Archimedes at the siege of Syracuse, and the true role of Prometheus, who brought fire to man from heaven. A review of ancient optical theory takes the argument deep into esoteric realms of Gnostic and alchemical thought. Stonehenge as astronomical instrument is discussed--including the startling proposal that the great circle was originally roofed with a dome. Inevitably, perhaps, the argument eventually makes its way to Egypt, real or imaginary home of all mysteries. Here, in the long final section of the book entitled "The Eye of Horus", Temple excels himself. The scale and precision of Egyptian monuments require sophisticated surveying techniques and a supporting mathematics. Temple finds these hidden in myths, partially disguised in tomb paintings embodied in the very structure of the buildings themselves. Above all, it seems, the Egyptians used light and shadow with great virtuosity. The Pyramids themselves, once clad in smooth, reflective white marble, and casting precise shadows across each other, are characterised as mystical surveying instruments on the hugest possible scale.
Temple is an engagingly garrulous and eccentric narrator, constantly interrupting himself, leaping forwards and back, starting hares he cannot pursue, pausing for personal paranormal reminiscences, but his passion and erudition are never in doubt. And is it true? Few readers can be in a position to decide. Reserve judgement, then, and enjoy an exhilarating intellectual adventure. --Robin Davidson

Scholarly, annotated, appendixed and indexed - and riveting! Staring us in the face for centuries, and Temple gives us permission to see. Absolute cracker.

Robert Temple's new book sheds interesting new light on the subject of lens' in antiquity. I was disappointed however, that this version of the book does not contain a full review of the lens he has found in the course of his research. That the work is painstakingly researched is not in doubt, but it seems that Temple takes delight in alienating the one group of people who would truely appreciate his dedication - other historians - by denigrating them as blinded and against new ideas. One cannot help but feel that if Temple presented his work in a less popular more scholarly fashion his ideas would be more readily accepted. On the whole this book is interesting and does help to resolve general unanswered questions about lens' in antiquity - the evidence for the use of corrective lens' is around us everyday in the form of modern lens wearers, a group of people who would not exist without intervention in the past. Whilst his review of useful lens' exising in antiquity is excellent, Temple's other remarks on theory and religion should be taken with a pinch of salt, too much is left out for the average reader to be able make an imformed choice. This is a difficult subject tackled in a format that makes it accessible to many, however I feel that Temple lets himself down by his anti-historian stance and the inclusion of too much subjective theorising.

Scintillating! Facts, facts and more facts, with ample footnotes, diagrams, photos, explanations for everything mentioned in this amazing 642 page tome (paperback version) and for a highly technical subject it is written in an easy to read way. I now own four amazing books by this author, and hope he writes more before he shuffles off this mortal coil.
This book will truly make you see history in a different light literally, as proof now exists of lenses in ancient history. The implications of reflecting and refracting, measuring, and magnifying, which explain The Pharos of Alexandria, Roman towers used for sending signals, minute carvings, Archimedes' death ray, how the Dogon tribe know about Sirius B's eliptical period, the Comma of Pythagoras, and how the Giza Pyramids were set out.
Illuminating and recommended.

Probably correct.
I don't see why the claims of this book should not be accepted if the proof is valid.
There is nothing particularly controversial. It just claims that ancient Rome had optics made from crystalline rocks. (Possibly earlier groups of people also). We use quartz crystals today for some optical solutions. There is no reason why the ancients could not have figured out how to make lenses.

I bought this book because of Temple's earlier work.He is an detective/historian of the highest caliber.Temple PROVES that the Romans used Crystal lenes, but so did the Carthigans, the Greeks and the Assyrians.His connection between Stonehenge and the Pyramids of Giza are ones most historians looked over because it didn't fit into there view of the world they lived in.His book proves that historians willfully changed passages to fit there history, and Temple proves his theorys! Even his history with the now deceased directer Stanley Kubrik was informitive! Temple doesn't just throw out ideas,he throws out evidence a missing link to history most will never have.His other books are still gems in my collection and this one will fit very well with my collection.If you want to know more about history read this book, you won't be sorry!
