Who built the megaliths, those massive stone structures ranging from tombs to standing stones that date back to over 4000 BC? Why were they built? How were the enormous stones transported and erected? Were these strange, sacred stones used as temples or tombs, sculptures or houses? Covering the best-known sites - Avebury and Stonehenge in England, Carnac in France and Knowth in Ireland - and also less famous examples in Scandinavia, Malta, Egypt and Spain, this book considers the special significance - architectural, scientific, religious and cultural - of these enigmatic Neolithic stone structures.

When his archaeologist parents go missing in Central America, fourteen-year-old Max embarks on a wild adventure through the Mayan underworld in search of the legendary Jaguar Stones, which enabled ancient Mayan kings to wield the powers of living gods. Includes cast of characters, glossary, facts about the Maya cosmos and calendar, and a recipe for chicken tamales.

"A fascinating exploration of our early ancestors' obsession with stone. With more than 250 stunning full-colour illustrations, Magic Stones is the most wide-ranging photographic record ever published on the megalithic monuments of Europe"--Back cover.

Heritage stones are building and ornamental stones that have special significance in human culture. The papers in this volume discuss a wide variety of such materials, including stones from Europe, Asia, North and South America, Africa and Australia. Igneous (basalt, porphyry, granite), sedimentary (sandstone, limestone) and metamorphic (marble, quartzite, gneiss, soapstone, slate) stones are featured. These have been utilized over long periods of time for a wide range of uses contributing to the historic fabric of the built environment. Many of these stones are of international significance, and so are potential Global Heritage Stone Resources, that is stones that have the requisite qualities for international recognition by the Heritage Stones Subcommission of the International Union of Geological Sciences. The papers bring together diverse information on these stones ranging from their geological setting and quarry locations to mechanical properties, current availability, and uses over time. As such the papers can serve as an entry into the literature on these important stones.

Ethnographic and archaeological records feature a rich body of data suggesting that understandings of the mineral world are in fact both culturally variable and highly diverse. Soils, Stones and Symbols highlights studies from the fields of anthropology, archaeology and philosophy that demonstrate that not all individuals and societies view minerals as commodities to be exploited for economic gain, or as passive objects of disembodied scientific enquiry. In visiting such diverse contexts as contemporary India, colonial-period Australia and prehistoric Europe and the Americas, the papers in this volume demonstrate that in pre-industrial societies, minerals are often symbolically meaningful, ritually powerful, and deeply interwoven into not just economic and material, but also social, cosmological, mythical, spiritual and philosophical aspects of life. In addressing the theme of the mineral world, this book is not only unique within the social and geo-sciences, but also at the forefront of recent attempts to demonstrate the importance of materiality to processes of human cognition and sociality. It draws upon theoretical developments relating to meaning, experience, the body, and material culture to demonstrate that studies of rock art, landscapes, architecture, technology and resource use are all linked through the minerals that constantly surround us and are the focus of our never-ending attempts to understand and transform them.

Many people know more about the planets Venus and Mars than they do about our home planet, Earth. Unique in our solar system, and so far as we know in the Universe itself, the Earth has been evolving for the past five billion years, and is the result of the dynamic interplay of astronomical,physical, and chemical forces ranging from the vast to the barely perceptible. The evolution of the Earth has never been predictable. Life has come very close to being extinguished many times. After each such crisis, the survivors and their genes have diversified and grown in number to exploit allopportunities. Without such traumas it is hardly likely that evolution's pace could have reached its present advanced level; that of conscious life capable of changing the world, contemplating it, and in doing so changing itself at geologically stupendous rates. In Stepping Stones, Stephen Druryexplores how such a seemingly fragile world could have been formed and developed. Looking at the astonishing leaps, and near catastrophes that have occurred along the way, intermingled with inexorable but slow change, the book interweaves the evidence from geology, physics, biology, and chemistry,to tell an extraordinary story of the Earth's evolution spanning nearly five billion years.
