Did you know which real-life incendiary weapon inspired the Wild Fire In Game of Thrones? In The Battle of Blackwater Bay, Tyrion’s trick with Wild Fire saves King’s Landing and the residents of the Red Keep, but it was actually inspired by Greek fire. Greek Fire was an incendiary weapon used by the Eastern Roman Empire beginning in 672 AD. It was invented during the reign of Constantine the forth Pogonatum, by Callinicus, of Heliopolis, a Greek-speaking Jewish refugee. Used to set enemy ships on fire, it consisted of a combustible compound emitted by a flame-throwing weapon. Some historians said it could be ignited on contact with water, and was probably based on naphtha and quicklime. The substance could be thrown in pots or discharged from tubes; it apparently caught fire spontaneously and could not be extinguished with water, which are all signs of the Westerosi Wild Fire.
