The ruins of ancient Athens, Luxor, and Rome are familiar cornerstones of world history, visited by travelers from across the globe. But what about the cities that have dropped off the map? Where are they, and what can they tell us about our past? In this compendium of forgotten cities, Philip Matyszak explores the trials, tribulations, and triumphs these cities faced.

Ancient Greece and its mythology has fascinated people for thousands of years, and few elements have intrigued people quite like the Eleusinian Mysteries, which the Greeks believed transformed the initiates and gave them knowledge that eased both the living of life on earth and allayed fears of death, allowing an acceptance of their ultimate fate. The influence of the Eleusinian Mysteries was also far-reaching.

Worship of the Feathered Serpent can be traced back 2,000 years, and the Serpent’s cults appear all across Mesoamerica. The Olmec, the Aztec, and both the Yucatec and K’iche Mayans all had different names for this deity, including Kukulkan, Q’uq’umatz, and Tohil...Quetzalcoatl was and remains one of the most interesting and enlightening stories ever to have come out of any civilization, and his stories offer a better understanding of the Mesoamerican world.

Built at the end of the last ice age, the mysterious stone temple complex of Göbekli Tepe in Turkey is one of the greatest challenges to 21st century archaeology. As much as 7,000 years older than the Great Pyramid and Stonehenge, its strange buildings and rings of T-shaped monoliths - built with stones weighing from 10 to 15 tons - show a level of sophistication and artistic achievement unmatched until the rise of the great civilizations of the ancient world, Sumer, Egypt, and Babylon.

The barbarian nomads of the Eurasian steppes have played a decisive role in world history, but their achievements have gone largely unnoticed. These nomadic tribes have produced some of the world’s greatest conquerors: Attila the Hun, Genghis Khan and Tamerlane, among others. Their deeds still resonate today. Indeed, these nomads built long-lasting empires, facilitated the first global trade of the Silk Road and disseminated religions, technology, knowledge and goods of every description that enriched and changed the lives of so many across Europe, China and the Middle East.
