The Cheirosyphon, the portable Greek firearm
Greek fire was an incendiary weapon used by the Eastern Roman (Byzantine) Empire that was first developed c. 672. The Byzantines typically used it in naval battles to great effect, as it could continue burning while floating on 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.
