Fire arrows were one of the earliest forms of weaponized gunpowder, being used from the 9th century onward. Not to be confused with earlier incendiary arrow projectiles, the fire arrow was a gunpowder weapon which receives its name from the translated Chinese term huǒjiàn (火箭), which literally means fire arrow. In China a 'fire arrow' referred to a gunpowder projectile consisting of a bag of incendiary gunpowder attached to the shaft of an arrow. Fire arrows are the predecessors of fire lances, the first firearm.
