Greek fire: Byzantine incendiary weapon, its deployment and lost formula

Key facts
- Greek fire was a Byzantine incendiary weapon, also known as sea fire, Roman fire or liquid fire, said to burn at well over 1,000 degrees Celsius and to be inextinguishable by water.
- It was deployed through a siphon placed on ships or on siege engines called chyrosiphons; a portable handheld version similar to a flamethrower also existed.
- Greek fire-filled jars were poured onto enemy ships using cranes called gerania.
- The Byzantines described the invention as divine intervention, claiming the composition was revealed by an angel to the first Christian emperor Constantine and would never be disclosed.
- Around 1100 AD a Byzantine princess described the fire as resin collected from pine and other evergreen trees, rubbed with sulfur and put into reed tubes, then blown by men with continuous breath.
- From around 1204 AD the secret composition of Greek fire was apparently lost, with no later chemist able to replicate it.
- Enemies adapted to the weapon: Muslim navies stayed out of its range and used felt or hides soaked in vinegar as protection, and at sea the weapon required calm conditions and favourable wind.
- The video cites melting points of basalt at about 984-1260 degrees Celsius and granite at about 1215-1260 degrees Celsius, used to assess whether heat damage could account for the affected statues.
