Throughout human history, mankind has strived to create new and inventive ways of killing. Countries conquered and empires shattered on the backs of the most lethal weapons of the ancient world. From the ancient napalm, Greek Fire, to the weapon that helped the Mongols create the largest ancient empire, the composite bow; the speedy battlefield chariot which changed battle tactics.

Greed, genocide, political manipulation and murder most foul -- these dictators would stop at nothing to make sure their names went down in history as the greatest rulers to have ever lived. Julius Caesar, Genghis Khan, Attila the Hun, Cleopatra -- they are the names you know, with the facts you don't.

The ancient Greeks are credited in the western world for inventing philosophy, democracy, and...robotics? Pioneering technological inventors, the ancient Greeks created inventions that were seemingly impossible: an ancient death ray constructed by Archimedes, Heron's automatic doors, Philon's ingenious use of robotics.

Think you know the ancient world? Think again. To this day, there are still mysteries surrounding the ancients that have us questioning what we know about these incredible civilizations. Secrets that demonstrate incredible technology comparable to our own.

Behind every great empire there is a central metropolis, driving expansion and governing the great empires that called these cities home -- hubs of technology, politics, engineering and massive populations comparable to cities of today.

Rome. This incredible civilization forged the world as we know it, creating some of the most technologically advanced engineering of antiquity that is still in use today. Such ingenious inventions include: super powered concrete, aqueducts stretching for miles, and sophisticated mining techniques that were years ahead of their time.
