Cannon

n. large gun

A cannon is any large tubular firearm designed to fire a heavy projectile over a long distance. They were first used in China, and were the archetypal form of artillery. The first cannon in Europe probably appeared in Islamic and Christian Spain. English cannons were first used during the Hundred Years War, when primitive cannons were used at the Battle of Crécy in 1346. The end of the Middle Ages saw the construction of larger and more powerful cannon, and their spread in warfare throughout the world. Asia saw the construction of some of the world's largest cannon, such as the Indian Jaivana cannon.

A heavy metal tube used for firing ordnance. First in service around 1300, the very first cannons fired heavy arrows, but soon stones were used as well. Gunpowder, formed of saltpeter, sulphur, and charcoal were found in Europe, they were used on a large scale only after 1325. Edward III used them at the siege of Calais in 1346, but the new weapon did not achieve any military significance until the late 15th century.
