Culverin

A culverin was initially an ancestor of the hand-held arquebus, but the term was later used to describe a type of medieval and Renaissance cannon. The word is derived from the antiquated "culuering" and the French couleuvrine (from couleuvre "grass snake", following Latin: colubrinus, lit. 'of the nature of a snake'). From its origin as a hand-held weapon it was adapted for use as artillery by the French in the 15th century and for naval use by the English in the 16th century. The culverin as an artillery piece had a long smoothbore gun barrel with a relatively long range and flat trajectory, using solid round shot projectiles with high muzzle velocity.
