Byzantine `Greek Fire` hand grenade or firebomb

A grey ceramic piriform vessel with a thickened rim enclosing a narrow circular mouth and decoration of incised lotus leaves around the shoulders.
Supplied with a metal display stand.

Height of the vessel 10.5 cms (4.1 ins).

Circa 12th-14th century AD.

From a collection of a North London gentleman, latterly with a London gallery.

Contemporary accounts indicate that like an early form of Molotov cocktail, such vessels were filled with flammable material such as naphtha a wick was inserted into the aperture and lit, and the whole vessel hurled at the enemy. They were mainly used in naval engagements and would have been devastating against wooden ships.
There was at one time considerable controversy over the purpose of these items, however an article published by W. Arendt in 1931 established beyond doubt that they are grenades.
