Greek fire (redirected from Callinicus of Heliopolis)

Greek fire, a flammable composition believed to have consisted of sulfur, naphtha, and quicklime. Although known in antiquity, it was first employed on a large scale by the Byzantines. Bronze tubes that emitted jets of liquid fire were mounted on the prows of their galleys and on the walls of Constantinople. The Byzantines in 678 and again in 717–18 destroyed two Saracen fleets with Greek fire.

Greek fire

Any of several flammable mixtures used in ancient and medieval warfare, particularly a petroleum-based mixture invented by the Byzantine Greeks in the 7th century. Flammable materials such as pitch and sulfur had been used in war since ancient times, but true Greek fire was especially deadly. Thrown in pots or discharged from tubes, it apparently caught fire spontaneously, and water could not put it out. Greek fire launched from tubes mounted on ship prows wrought havoc on the Arab fleet attacking Constantinople in 673. Its effectiveness was a prime reason for the long survival of the Byzantine Empire. The recipe was so secret that its precise composition remains unknown.
