Greek fire

Greek fire was an incendiary weapon used by the Byzantine Empire, typically projected from siphons on warships, and able to burn on water. Its exact composition was a closely guarded secret and remains uncertain. It played an important part in Byzantine naval defence, notably against Arab fleets of the Umayyad Caliphate during the sieges of Constantinople.
