Circa 800-1000 AD A late Roman, early Byzantine glazed ceramic grenade, also referred to as “Greek Fire”. This hollow ceramic vessel is globular in shape, a piriform body, with a short neck and a domed rim. The body is decorated with an incised patterned motif which is encircling the whole body. “Greek Fire” was intended to be filled with explosive liquid and a wick and used as a hand grenade. Typically, it was used in naval battles as it could continue burning while floating on the water. For similar grenades see Arendt, W. I., Granaten des 13-14.
