Ancient Impossible reveals how many of today's technological achievements were actually developed centuries ago. Colossal monuments, impossible feats of engineering, and technologies so precise they defy reinvention. The ancient world was far more advanced than we ever imagined.

Now, new science uncovers a lost world more like our own than we ever suspected, and reveals how modern technology has its blueprint in the ancient world.
