A Ribaulequin, also known as a rabauld, ribault, ribaudkin, or organ gun, was a medieval volley gun with many small caliber iron barrels set up parallel on a platform, which, when fired, were somewhat akin to machine guns of modern times, and mainly used in an anti personnel role. They are sometimes defined as an early or even as the earliest machine gun. When the gun was fired in a volley, it created a shower of rapid iron shot. They were employed, specifically, during the early fifteenth century, and continued serving, mostly, as an anti-personnel gun.
