The groundbreaking, bestselling series--millions of copies sold worldwide!A classic of ancient human history--and one of the inspirations behind the History Channel's Ancient Aliens--Zecharia Sitchin's Earth Chronicles series is the revelatory and deeply provocative masterwork that forever altered humankind's view of our history and our destiny. In the sixteenth century, Spanish conquerors came to the New World in search of El Dorado, the fabled city of gold. Instead, they encountered inexplicable phenomena that have puzzled scholars and historians ever since: massive stone edifices constructed in the Earth's most inaccessible regions ... great monuments forged with impossible skill and unknown tools ... intricate carvings describing events and places half a world away. Who were the bearded "gods of the golden wand" who had brought civilization to the Americas millennia before Columbus? Who were the giants whose sculpted stone heads in Mesoamerica still mystify to this day?In this remarkably researched fourth volume of The Earth Chronicles, author and explorer Zecharia Sitchin uncovers the long-hidden secrets of the lost New World civilizations of the Olmecs, Aztecs, Mayas and Incas, and links the conquistadors' quest for El Dorado to the extraterrestrials who searched there for gold long before.
