SH Archive Square cannon: what kind of cannon is that?

[KD Archive]

Who knows what kind of projectile was used for this cannon? Bricks? I understand that the official version would probably say that some sort of fragmentation was used, but older cannons have something to them.

What about this one?

​

I’ve been thinking about a serious thread on cannons, for I think some of them could be something else. Hopefully will get to it one day.

If cannons were indeed used like trumpets or (sound) resonance amplifiers, then the shape of the chamber and "exhaust" hole(s) changes the resulted resonance/sound/frequency. Do check out the air/steam cannons thread, if it was imported here (I can't find it). Maybe they simply used them without the balls, or the balls were put on the other side of the gunpowder, or were used to pack more gunpowder into the cannon before taking the cannonball out.

It is also possible that the cannonballs were somehow charged with some type of energy, energy which was dispersed after sitting out in the open for at least months, possibly years after use. That way, the thing which was supposedly used to shove gunpowder and the cannonball actually was used to clean the cannon, and the cannonball hitting the back of the cannon would somehow release the energy, with a small hole on the top to release the energy on the other side of the cannonball, too. Think of an air cannon functioning like a gong, by having the bottom part be hit by the cannon ball.

I do have to make a link connection to this thread, though: Ancient Cannons aka Ball Mills aka Cement Kilns?

Funnily enough, the bottom (round) cannon looks a lot like a salt-shaker (or spices-shaker) built for giants.

Square cannon? What about "ninety-degree-corner-cannon"?

Stumbled over this image here on this antique prints online shop. It's a page out of the Encyclopaedia Londinensis from 1810...

Fig.1 is kind of goofy but Fig.8 looks more like some aparatus that could be used for some kind of galvanic process.

Sorry for the double post, but something that came to mind when seeing that "square cannon" from the OP: What if it is a Waveguide/hollow conductor? Maybe that square cannon we are looking at, is just a piece of a set? A waveguide filter?

This ties even more in the theories stating that Tartaria used sound and frequency to stay healthy and live (millenia) long lives, before they fell/declined and collapsed.
