Mysterious world

For years, Arthur C Clarke has been fascinated not only by the spaceships and technology of the future which form the landscape of his bestselling books but also by the ancient enigmas which have survived since before the pyramids, and by the present-day visions of undiscovered animals, unknown sea-creatures and UFOs. What is the vast and complex tomb of newgrange in Ireland, probably the oldest building in the world? Does an Abominable Snowman stalk not only the himalayas, but also the mountains of North America? What is the truth about the fearsome Mitchell-Hedges skull, the weirdest Gemstone in the world?... And a lot more. These puzzles, which have caught men's imagination across the globe, are brought together in this book under the direction of the one man with both scientific training and the breadth of vision to document the mysterious world.
