Petraria Arcatinus


What is a Petraria Arcatinus? Roughly translated, it means "Bow powered rock hurler". There has been much debate over whether these machines actually existed or not. There is very little in the historical record to suggest a machine like this, but there are a lot of artists drawings from ancient times depicting bow powered, spoon armed machines.

We built a lot of machines based on those drawings, and they usually didn't work worth beans. But, taking what we learned and committing to creating a bow-powered catapult that really works, we eventually discovered this design.

This elegant little machine is highly versatile. Capable of hurling just about anything ranging in size and weight from marbles to baseballs. We were able to hurl golf balls about 50 feet, and baseballs sailed nearly 20 feet! Powered by a bow with a 50 pound pull, this little machine is only 18 inches long and 10 inches wide. The arm reaches 18 inches high at rest.

Look at these features:
+ Hand Crafted From High Quality Wood
+ Real Working Winch
+ Real Leather Strike Bar
+ STRONG Spring Steel Bow
+ Genuine Wrapped Bow-String
+ All Hardwood Wheels and Frame

The detailed instructions are complete with diagrams, photos, and tuning tips. All parts are pre-cut, pre-drilled and can be assembled to a finished model in one evening, plus glue-drying time.

Interesting Notes

What is a Mangonel?


The term "mangonel" literlally means "engine of war." It is a ballistic device, usually some type of artillery. In other words, a catapult. But "catapult" is a more general word that includes a broad range of things that use mechanical means to shoot a projectile, including slingshots and aircraft carrier launch systems. So a mangonel is a unique type of catapult.

The word Mangonel derives from the ancient Greek word "Manganon", literally meaning "engine of war". The Romans called it a Manganum. In pre-medieval French the word Manganum was changed to Manganeau, and the English changed that to Mangonel in the 1300s.

The history gets a little sketchy in the middle ages, but some historians believe that "mangonel" was shortened to the word "gonnel" about the same time that cannons were being developed, and later still, "gonnel" was shortened to "gun." And to this day, in the military a gun is strictly big artillery. (Rifles and pistols are referred to as "weapons", NOT "guns".)

The three most common types of ancient mangonels are the Greek Ballista, The Roman Onager, and the Trebuchet.

In France, the word Mangonel is used for a Trebuchet that uses a fixed counterweight for power. (The other kind of trebuchet, the hanging counterweight type, is called a "Trebuchet". Go figure!)

The English use the term Mangonel and Onager interchangeably for the Roman single-arm torsion machine.

The Greek catapult, probably the first machine to be called a mangonel, was also known as the Ballista and is where we get the word "ballistic".
