Catapult Design, Construction and Competition


Now available in print! TWO historical catapult reference works in one volume!

This Is The Best General Catapult Book You Can Find Today!

Catapult Design, Construction and Competition with The Projectile Throwing Engines of the Ancients and Foreword by Ron Toms

If you've ever wondered how to build a catapult or trebuchet, or wondered what you'd do with it once you've built one, then this book can help. Filled with anecdotes, plans, photographs, drawings and detailed descriptions of the workings and history of all the major types of catapults, these pages will help you get started in this fascinating hobby. You too will feel the joy of harnessing the power and energy of simple and ancient machines.

Those who involve themselves with a catapult project invariably find within themselves the enthusiasm, lit by a private spark of wonder, to participate meaningfully in the work. Almost at once and without planning, the task draws participants into a mature collaboration many have never known before. Here is a project that teaches one how to learn-- not to parrot, but to generate knowledge. Catapultors discover that they are collecting real information concerning a phenomenon about which very few people in the world know anything.

It's easy to design a simple machine with modern tools and materials, but when you constrain the project to use only tools and materials available from a thousand years ago, and require that machine to compete with modern equivalents, then you start to see a lot of creativity sprout up. It's a puzzle, a challenge that inspires people to learn and it generates new respect for the ancients and their ingenuity.

The ancients had limited power and resources available, and had to concern themselves with efficiency and clever applications of leverage and other basic principles of physics. Helping kids to learn how they did these things in the Medieval world also helps those kids compete in today's world by inspiring them to be more creative and do more with our limited resources.

Catapult Design, Construction and Competition is a truly unique book that describes all types of catapults, including tension bow powered machines, ballistae, onagers and mangonels, and of course, trebuchets! There are a multitude of photographs, including some truly large machines that can hurl 100 lb. missiles! But there's more than just pictures. Schematics are included for four of the record setting machines, and detailed descriptions of their construction too.


This book also includes the results of early catapult and trebuchet competitions, and the rules and regulations for holding your own competitions. Including the definition of what is a catapult, safety, classes and categories of machines, judging, registering results, and lots of other details.

The Projectile Throwing Engines of the Ancients


This is one of the most important books in the history of hurling. Written by Sir Ralph Payne-Gallwey in 1907, it's the first serious work on the ancient catapults to be written in modern times.

In this book, Sir Ralph explores the ancient writings of seiges and their artillery. Not content to take the writings at face value, he endeavors to assign credibility to the writer, then he goes on to produce his own working versions of the ancient machines, to test the principles and the claims of the ancient writers.
The original book is out of print and extremely rare. Reprints can sometimes be found at prices ranging from $70 to $150 and more. We've taken great care to preserve all the original information in this edition.


Containing forty-four pages with over 22 illustrations, the book gives details about the design, construction and operation of the three fundamental types of siege engines- the Catapult (also known as the Mangonel or Onager), the Ballista and the Trebuchet, as well as the history and effects of such weapons.

Catapult

A catapult is any kind of device that shoots or launches a projectile by mechanical means. In England, a catapult is what we call a slingshot in the US. A catapult is also the part of an aircraft carrier that launches airplanes off the deck.

But for our purposes, a catapult is any of the ancient types of artillery, including Onagers, Scorpions, Trebuchets, Ballistae, Springalds, Coullards, Bricoles Perriers and more.

But most people tend to think of a catapult as the one-armed torsion machine used by the Romans. This is also known as the Onager or Mangonel.

Mangonel

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 still today, in the military a "gun" is strictly a piece of big artillery.

Onager

Onager is originally the name for the wild Asian donkey. This donkey bucks like a bronco if anyone gets too close to it, and it is known to kick stones at people and predators too. So when the Romans needed a name for their one-armed torsion catapult, they called it the Onager!

The Onager (catapult) has a single arm that is powered by a large skein of twisted ropes. The ropes were usually made from hair or sinew for their elastic properties.

Trebuchet

The word "Trebuchet" is originally French, and meant something like "to fall over or rotate about the middle" as in a see-saw rotating on its axle. It also seems to have meant a big, heavy beam. Today a Trebuchet is any kind of catapult that is powered by a massive counterweight on one end of an arm, and a sling on the other end. This includes Perriers, or "traction" trebuchets which are powered by a mass of people pulling one end of the arm with ropes.

Ballista

This is a two-armed torsion device invented by the Greeks. It works similar to a crossbow, but instead of a flexible bow, it uses two stiff arms powered by twisted rope skeins like an Onager. The ballista predates the Onager by several centuries and was used to hurl stones (lithobolos style ballista) and also bolts or darts.

Obviously, this is where we get the word "ballistic".
