There aren't many of this class of old firearms from the 18th Century above ground. That's because they are firearms designed to take on grave robbers.
Grave robbers worked at night so as not to be seen, but this also meant that they may not see these guns mounted on a grave, and would probably not see the trip wires.
Several trip wires could be fitted to the trigger mechanism, running in different directions. This not only covered a wide area, but it also meant that any one of these wires could swivel the gun in the direction of the intruder. (h/t)
They were referred to as "Grave Guns" or "Cemetery Guns".
This blog has many elements and depending on your interests, may pique your imagination...or not. I urge you to be unreasonable. Reasonable people adapt themselves to the world. The unreasonable persist in trying to adapt the world to themselves, therefore all progress depends on unreasonable people. The more unreasonable you are, the more likely you are to enjoy this blog. All men dream, but not equally.
If you're a socialist or a Marxist, you'll find that I poke fun at your absurd notions of "good government" on a regular basis. So you might not wish to follow this blog because you'll be offended.
John Locke said, "One unerring mark of the love of truth is not entertaining any proposition with greater assurance than the proofs it is built upon will warrant." I like what Locke said. We can't theorize without adequate information because when we do we inevitably twist facts to suit theories rather than theories to suit facts. In this blog and in my life, I try to maintain this perspective.
Either you believe in our essential spark of shared divinity, or you succumb to our human insecurity. Either way your conscience lets you slice it, the main thing is to earnestly do what is right at the time.
Today, I balance work and play as much as anyone can. All things remaining equal, play is more important. Life is short - it's important to make every day count for something, if only to yourself.
I'm a former tinker/tailor/soldier/sailor who has now decided that maybe it really wasn't all done for nothing.
