Ribauldequin

A Ribauldequin, also known as a rabauld, ribault, ribaudkin, infernal machine or organ gun, was a late medieval volley gun with many small-caliber iron barrels set up parallel on a platform, in use during the 14th and 15th centuries. When the gun was fired in a volley, it created a shower of iron shot. They were employed, specifically, during the early fifteenth century, and continued serving, mostly, as an anti-personnel gun. The name organ gun comes from the multiple barrels with the likeness of pipe organ.
