Where Did It Come From? Ancient Greece: Modern Ship Building (DVD/ Documentary)

Product Overview

Modern warships, cargo, and container ships are the cutting edge of maritime technology. But 2,500 years ago, no one dominated shipbuilding like the Greeks. We travel to Greece for a firsthand look at how their maritime expertise evolved. We examine a reproduction of the Greek warship called a trireme. A 3-D CGI reproduction captures the grandeur of the gigantic cargo ship the Syracusia. Host Michael Guillen demonstrates an Archimedean Screw--designed to pump water out of a ship's hold. He also demonstrates Archimedes' most famous discovery: the principle of buoyancy, a key component in any shipbuilding process. In England, we investigate the Antikythera device. After decades of study, historians have concluded that it was actually a celestial computer that tracked the movement of the Sun, Moon, Mars, Venus, Mercury, and a handful of stars. And on the Greek island Kalymnos, we learn how sponge diving evolved into the lucrative business of salvage diving.
