Cannons are large artillery weapons that use an explosive charge to propel a projectile. Historically, they were mounted on wheeled carriages for field use or installed on fortifications and ships; their heavy barrels and supports helped crews aim and manage recoil. The collection's references span antique and 18th-century pieces, a World War I cannon, and a bronze signal cannon, reflecting both combat and ceremonial roles. Pounder designations, such as 6-pounder or 9-pounder, traditionally refer to the weight of the cannonball a gun was designed to fire. Cannons also appear in modern popular culture, including a title referencing Fortnite, broadening the subject beyond historical artillery.
