A Byzantine grey ceramic vessel featuring a hollow globular body with a pointed base. A circular incision presents near the top of the body, possibly to help with grip. A large chip at the top of the grenade where the mouth and neck would have been, leaving only a small hole. Such item would have been filled with an explosive liquid known as ‘Greek Fire’ and used as a hand grenade. A few chips around the vessel and slight earthly encrustations to the surface. Greek fire, also referred to as liquid fire, was the most famous weapon in the Byzantine arsenal, saving the Byzantines for centuries from Arab attacks. Being used in both defence and attack situations, the weapon proved significant in the survival of the Byzantine Empire. The formula for the flammable mixture was closely guarded for centuries and irredeemably lost after the collapse of the Empire. Its precise composition thus remains unknown to this day, though research suggests the use of petroleum as a vital ingredient. Their average size and grip suggest the vessel being thrown by hand, in short-range conflicts, but this does not exclude the use of grenades in long-distance battles and at sea; as they were most likely hurled by catapults. Measurements: L 10 cm x W 7.5 cm Provenance: Ex private UK collection, acquired 1990s.
