Reinoud de Jonge (a Dutch chemist) and Jay Wakefield (an American biologist) have specialized in the study of megalithic culture. They present their analysis of a dozen archaeological sites, showing how many petroglyphs are geographic maps. They show how megalithic monuments provide numerical data revealing megalithic religion and ancient sailing discoveries in the Atlantic. For example, numeric picture writing at Loughcrew, Ireland, deciphered by the authors, reveals that these people gave up their efforts to cross the Ocean west of Greenland in 3200 BC. However, decipherment of the petroglyphs at Dissignac, France, shows that they next explored the earth to the east, where they discovered Australia and Alaska. Subsequently, they found routes across the Atlantic, and built Stonehenge, the monument for the discovery of America.
These decipherments shed light on a number of mysteries in American prehistory, such as the origin of the Olmec civilization, the Michigan copper mines, and the stone chambers of New England. This is the only book providing solid evidence, reasonable explanations, and comprehensive dating for megalithic petroglyphs and monuments. The authored illustrate the predictive power of these decipherments in several instances. This book will fascinate anyone interested in old religions, little-known petroglyphs, ancient seafaring, voyages of discovery, and the prehistory of Europe and America.
