Sezon 2

Warfare technology is examined, including the Helepolis, a square fortified tower on wheels; and "Greek Fire," an incendiary liquid that stuck to people and objects and couldn't be extinguished with water.

The lake Nemi ships, large Roman vessels that were salvaged from the lake in the 1930s and burned in 1944, are discussed, including technological discoveries from the ships.

Ancient mechanical devices are examined: A jar that appears to be an electric battery, a flour mill in France that is run by waterwheels, and Archimedes use of solar power to defeat the Romans.
