The crusades saw Christian soldiers wield a terrifying array of medieval weaponry, including powerful crossbows, wickedly spiked maces and swords large enough to cleave a man in two.
But in the bloody battles over the Holy Land, the crusaders faced, and perhaps also used, weapons that were far ahead of their time – hand grenades.
Now one of these early explosive devices has been pulled from the sea in northern Israel.
A 700-year-old hand grenade (pictured) made from clay has been found in the sea off the coast of northern Israel. It is thought to date from around the time of the Crusades and would have been filled with a flammable liquid with a fuse poked in the top
The clay device, which would have been filled with a flammable liquid with a burning fuse poked through a hole in the top, is thought to be about 700 years old.
These grenades were flung at enemy ships in an attempt to burn the wooden vessels.
