3/4. In 1900 a strange lump of rusty metal was discovered on the Mediterranean seabed: a 2,000-year-old piece of highly complex engineering, the like of which was not previously thought to have existed until 1,500 years later. What had happened to halt the progress of the societies of the East - the Greeks and the Persians - who utilised such ancient knowledge? Terry Jones blames the Romans.
