Ancient Impossible, the new H2 series, picks up where HISTORY’s long running Ancient Discoveries left off. In this next generation of storytelling, 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. We’ll travel through history to reveal a radically different picture of the past, with innovations so far ahead of their time, they’re still in use today. 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.

Moving Mountains

#3 - Moving Mountains

Season 1 - Episode 2 - Aired Jul 6, 2014

How did the Ancients move impossibly huge objects? Why did the Roman forces at the siege of Masada decide to shift an entire mountain by hand? We reveal the ancient technology that allowed the Egyptians to move a 1,000 ton obelisk, and show how the Romans moved even heavier objects at the temples at Baalbek. As well as moving stone and earth, the ancients needed to move mountains of water, using technology we still find impressive today. Who were the most successful Mega Movers of the ancient world and how were they able to make the impossible...possible?

Ultimate Weapons

#5 - Ultimate Weapons

Season 1 - Episode 1 - Aired Jun 29, 2014

We think of weapons of mass destruction as a modern concept, but the ancients also created fearsome weapons of their own, some even more destructive than we can create today. Centuries before the widespread discovery of gunpowder, one ancient genius managed to build a cannon that could fire a projectile using the power of steam! We reveal an ancient troop ship mightier than an aircraft carrier, and death rays that could burn enemy ships. How were the ancients capable of creating seemingly impossible warfare technologies thousands of years before modern times?
