An ancient incendiary weapon used by the Byzantine Empire, Greek fire involved a heavily guarded formula that we still can't figure out today.
Greek fire was a devastating incendiary weapon used by the Byzantine Empire to defend against their enemies.
The Byzantine people used this 7th-century arsenal to repel Arab invasion for years, particularly at sea. While Greek fire wasn’t the first incendiary weapon, it was arguably the most historically significant one.
What’s truly fascinating about Greek fire is that armies who captured the liquid concoction were unable to recreate it for themselves. They also failed to recreate the machine that delivered it. To this day, nobody knows exactly what ingredients went into the mixture.
