“Greek Fire,” the famous naval weapon of the Byzantine Empire, was a liquid projectile that burst into flames after spewing out of pressurized nozzles, and kept burning as it floated on water. This is a twelfth-century illustration of Greek Fire in action. The eleventh-century historian Anna Komnene has a great description of the theatrics involved with setting up the weapon: the Byzantine Emperor “had a head fixed of a lion or other land-animal,” on each ship, “made in brass or iron with the mouth open and then gilded over, so that their mere aspect was terrifying. And the fire which was to be directed against the enemy through tubes he made to pass through the mouths of the beasts, so that it seemed as if the lions and the other similar monsters were vomiting the fire.” The exact composition of Greek Fire is still unknown (probably calcium oxide and liquid hydrocarbon with some other ingredients).
