Ancient inventions episode 1 war and conflict

This episode was about the history of weapons and medicine. A couple of things it talked about was the belly bow, Greek fire, the super gun, gunpowder, the ballista and much more. The ballista was based off of the belly bow. A chinese alchemist accidentally discovered gunpowder. In the context of late medieval siege warfare the term superguns applies to stone-firing bombards with a ball diameter of more than 50 cm. These superguns were either manufactured by forging together longitudinal iron bars, held in place by iron rings, or cast in bronze with techniques generally similar to bell-founding. Known examples include the Pumhart von Steyr, Dulle Griet and Mons Meg (all iron) as well as the cast-bronze Faule Mette, Faule Grete and Dardanelles Gun. Greek fire was an incendiary weapon used by the Byzantine Empire. The Byzantines typically used it in naval battles to great effect as it could continue burning while floating on water.
