Earliest European Cannon Discovered Off Coast of Sweden | The Global Today

The earliest recognized instance of a European cannon was discovered off the coast of Sweden, close to Marstrand, in 2001. The invention and the age of the artifact have been not too long ago revealed. Handheld weapons, generally known as hand cannon, have been found from about the identical period.

Gunpowder began being talked about in European paperwork about 1300. The Chinese language had been experimenting with precursors of gunpowder and had some primitive firearms a bit earlier than 1300, as documented within the guide “Gunpowder” by Jack Kelly.

Army expertise has excessive incentives and travels quick. Whereas mentions of European makes use of of gunpowder and weapons have been present in paperwork from the early 1300s, stays of precise cannons have been lacking. The fourteenth century extends from 1300 to 1399. From tandfonline.com:

There are a selection of fourteenth-century references that document using cannon on ships however they not often, if ever, present any concrete particulars.Footnote³² One specific reference illustrates nicely the difficulties in decoding these early weapons Work carried out between 1337 and 1338 on an English vessel, the All Hallow’s Cog, included ‘a sure iron instrument for firing quarrels [. . .] and lead pellets, with powder, for the defence of the ship’.Footnote³³ We all know nothing concerning the kind or dimension of this ‘instrument’ besides that it was fabricated from iron and fired quarrels, that’s, giant arrows. That early artillery items fired arrows is nicely attested by each documentary proof and illustrations, such because the cannon depicted within the manuscript De Nobilitatibus, Sapientiis, et Prudentiis RegumFootnote³⁴ and the related quantity Pseudo-Aristotle, Secretum SecretorumFootnote³⁵ of round 1326-27, generally known as the Milemete manuscripts.

Metallic was costly in medieval Europe. Weapons that grew to become out of date or damaged have been recycled rapidly into different usable instruments. It was frequent for damaged weapons to be melted down and recast into newer weapons.

In the summertime of 2001, an area diver, utilizing scuba gear, discovered a small copper alloy cannon off the coast of Marstrand, on the west coast of Sweden. When he realized the historic nature of the artifact, he contacted the authorities. The authorities promptly confiscated the cannon, as licensed by Swedish legislation. America has an analogous however much more restrictive statute. In England, they’re extra affordable. If somebody finds historic treasure, they ordinarily can pocket 50% of the worth.

When the Swedish authorities examined the cannon, they discovered it contained what was left of a cost of gunpowder in a fabric bag, prepared to fireplace. The fabric allowed the cost and the cannon to be dated with carbon relationship.

Inside a 94.5% confidence stage, the cost was dated between 1285 and 1399, which makes the cannon the earliest European cannon but found. From thehistoryblog.com:

This bit of material made it potential to radiocarbon date the gun, a uncommon alternative with early artillery that’s sparsely documented and can’t be precisely dated by sort. With calibrated ends in the vary of 1285-1399, it is without doubt one of the oldest items of European artillery ever to be completely dated. Cannons of the Marstrand sort have been beforehand thought to this point the Fifteenth-Sixteenth centuries, as have been powder cartouches. This one discovery has redefined the timeline for European ship artillery.

The cannon is comparatively small however too giant for use by a single individual. It measures 47.5 centimeters long, or 18.7 inches. The cannon’s widest level is about 7.3 inches in diameter. The powder chamber is way smaller. The cannon is formed considerably like a slender funnel. The partitions of the cannon are comparatively skinny in comparison with the latter designs. The partitions of the cannon are about .4 to .6 inches thick on the muzzle and about 1 inch thick on the mouth of the powder chamber. The powder chamber is about 10.6 inches lengthy, the barrel is about 8.1 inches lengthy.  A tough estimate of the load of the closely corroded cannon, primarily based on the measurements given, is about 60 lbs.

The cannon would have been mounted on a picket platform of some sort, in all probability lashed into place. The contact gap of this cannon was measured at about .6 inches! It might have been enlarged by corrosion. You wouldn’t need any a part of your physique near the touchhole when the cannon was fired!

The copper alloy used, with little tin and about 14% lead, tends to crack over time.  As famous within the analysis of the cannon, it’s probably the cannon would have failed below intense use.

Bronze, with about 14% tin as a substitute of lead, is usually a robust alloy. Bronze made with ample tin can method the power of gentle, low-carbon metal. Later cannon makers used a lot superior bronze than the copper alloy used with this early cannon.

As we speak, the effectiveness of the cannon may very well be duplicated utilizing frequent gentle metal pipe. Muzzle-loading cannons are usually not thought of authorized firearms. Nonetheless, a minimum of one individual has been prosecuted as possessing a “damaging gadget” for making a muzzle-loading cannon out of contemporary supplies.
