Ancient Secret Agents

Today on Far Future Horizons we present another exciting episode of the acclaimed documentary series that focuses on ancient spy-craft. 

In this instalment of Ancient Discoveries we investigate the systems by which ancient intelligence services transmitted messages over thousands of miles - the fire beacon, the horse and the pigeon.

We learn how ancient spies sent secret messages using invisible ink made of human sperm and how they wrote on the inside of a raw egg. We also learn how Japan's covert assassins, the ninja, didn't only use darts and poisons. They were also pretty good with explosives as well. 

Finally, we learn how a Roman James Bond used a suit made of cork to support him in full armor during a covert operation across a river.

This and other exciting episodes in the Ancient Discoveries series can be purchased on DVD from the History Channel’s online shop, or in special DVD collections available in the United Kingdom through Amazon.co.uk.
