Our modern day landscapes are littered with the remains of ancient superstructures. Now, cutting edge archaeology is beginning to reveal that this century's most exciting discoveries actually lie at the bottom of the ocean.

Since the first time a rock was thrown in anger, mankind has endeavored to deliver larger, deadlier payloads further and faster. ANCIENT DISCOVERIES reveals how the science and technology of ballistics — a seemingly modern, cutting edge technology — actually dates back thousands of years to the ancient world. Using state of the art forensic techniques and the world's leading firearms experts, this groundbreaking show reveals the accuracy, power and range of ancient bullets, rockets and bombs.

The master shipbuilders of the Far East created the most deadly warships of ancient times in their quest for supremacy of the seas. Uncover the extraordinary ingenuity of the ancient engineers whose innovations would take shipbuilding to new heights and create some of the largest and most fearsome navies of the ancient world.

ANCIENT DISCOVERIES digs for the roots of today's war machinery. Throughout history, military requirements — killing more effectively than the enemy — have driven the leading edge of technological innovation. Almost all technology on the planet today owes its origins to inventions driven by the imperatives of war. This episode surveys the ANCIENT DEATH MACHINES that have left a legacy on today's battlefield. From apocalyptic skyscraper siege machines to ancient landmines and flamethrowers which had the potential to extinguish hundreds of lives in minutes, ANCIENT DISCOVERIES puts the lethal tech of yesterday to the test.

Using the latest scientific techniques to solve the greatest mysteries of the ancient world's naval technology, our team of modelmakers, underwater detectives and elite naval commandos are investigating legends that speak of lethal, high explosive grenades... covert underwater attack equipment... and highly toxic biological warfare. Their life-threatening experiments will forever transform our understanding of antiquity's greatest naval inventions.

Long before Wall Street and Broadway, before even the Dutch, New York was a special place. It's unique topography and resources made it an ideal settlement and so its history stretches far back before the arrival of Europeans. ANCIENT DISCOVERIES journeys back in time to experience the Big Apple when it was still the "Island of Many Hills." While New York's towering skyline and world-leading technology have made it the ultimate modern city, breathtaking new discoveries reveal that the blueprints for this megalopolis were in fact laid thousands of years ago. Now, through the wonders of CGI and dramatic reenactment, you can see first-hand how people have been "making it there" for thousands of years. Witness brutal blood sports staged in ancient Madison Square Gardens. And mark the passage of time — as if in Times Square on New Year's Eve — with a gigantic Neolithic calendar.
