A treasure hunt that uncovers the secrets of one of the world’s great civilizations, revealing dramatic proof of the extreme sophistication of the Celts, and their creation of the earliest accurate map of the world. Fifty generations ago the cultural empire of the Celts stretched from the Black Sea to Ireland and the Highlands of Scotland. In six hundred years, the Celts had produced some of the finest artistic and scientific masterpieces of the ancient world. In 58 BC, Julius Caesar marched over the Alps, bringing slavery and genocide to western Europe. Within eight years the Celts of what is now France were utterly annihilated, and in another hundred years the Romans had overrun Britain. It is astonishing how little remains of this great civilization. While planning a bicycling trip along the Heraklean Way, the ancient route from Portugal to the Alps, Graham Robb discovered a door to that forgotten world―a beautiful and precise pattern of towns and holy places based on astronomical and geometrical measurements: this was the three-dimensional “Middle Earth” of the Celts. As coordinates and coincidences revealed themselves across the continent, a map of the Celtic world emerged as a miraculously preserved archival document.
