I have come across two articles recently about the identification of what can only be construed as a twelfth century grenade from the Crusader kingdom in the Holy Land. Though such things were recorded the lack of evidence had made modern scholars sceptical as to their actual use and composition.
There are articles from Live Science at Mysterious ceramic jars may actually be 900-year-old Crusader hand grenades and from Sky News at Archaeologists discover 1,000-year-old 'hand grenade' among ancient ceramic shards in Jerusalem about this latest research.
Reading the articles led me to think of the Holy Hand Grenade of Antioch in Monty Python and the Holy Grail. I am not a particular fan of Monty Python, though the Holy Grail film is among their better work, but it seems appropriate to add the link to the Holy Hand Grenade of Antioch in this post.
