THE BIZANTINE GREEK FIRE SYPHON





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 even under water. It provided a technological advantage, and was responsible for many key Byzantine military victories, most notably the salvation of Constantinople from two Arab sieges, thus securing the Empire's survival. The impression made by Greek fire on the European Crusaders was such that the name was applied to any sort of incendiary weapon, including those used by Arabs, the Chinese, and the Mongols. These, however, were different mixtures and not the Byzantine formula, which was a closely guarded state secret, whose composition has now been lost. As a result, its ingredients are a much debated topic, with proposals including naphtha, quicklime, sulphur, and niter. What set the Byzantine usage of incendiary mixtures apart was their use of pressurized siphons to project the liquid onto the enemy.

Byzantine Greek fire syphon. I worked on this model little by little during 4 months. It's hand-made and fully functional I'm going to upload a movie on youtube to show you how it works.


I got inspired by descriptions made by Historians, so I decided to create this kind of model.

The mechanism is very simple, It works by filling out the combustible deposit, next you have to light the burner in front the dragon and finally you have to pump the piston.
