A Byzantine ceramic vessel featuring a hollow globular body with a pointed knobbed base. To the top, the vessel raises into a short narrow neck and splays out into a chipped rim with a small mouth. The body is undecorated. Chips and dents to the rim and the body, all consistent with age. Some earthy encrustations remain on the surface. Greek Fire was one of the most significant military inventions in history and its use saved the Byzantine Empire for centuries from Arab attacks. The precise composition of Greek fire remains unknown to this day, though research suggests that petroleum was a vital ingredient, making the liquid impervious to water. It was first used at sea where it was particularly effective against wooden ships, as it could not be put out by water. It was later delivered via clay grenades, either by hand or by launching with a catapult. Measurements: Circa H 14cm x W 8cm Provenance: Ex private UK collection, acquired 1990s.
