A matchlock or firelock[1] is a historical type of firearm wherein the gunpowder is ignited by a burning piece of flammable cord or twine that is in contact with the gunpowder through a mechanism that the musketeer activates by pulling a lever or trigger with their finger. This firing mechanism was an improvement over the hand cannon, which lacked a trigger and required the musketeer or an assistant to apply a match directly to the gunpowder by hand. The matchlock mechanism allowed the musketeer to apply the match himself without losing his concentration.
