This is a petraria; a novelty seige engine that is commonly seen in films. Though the existence of such devices is often questioned, they look far cooler than a conventional catapult. This petraria fires 1x1 cylinders a distance of between 6-9 ft depending how far the arm is drawn back.
This is cool, for a fictional siege engine. (^.^) Very cool. One of the best parts about loving Legos, is that it teaches you how to figure out how things work. I love how this is supost to work (if it was real) =) Great job. Once again, I ask you to make a treb, and please e-mail me when you do. Thanx!!!
My favorite "fictional" siege weapon! I would love to know how you release it though, it looks as though it just unwinds from the winch when released. There are very few good siege engine MOCs about, this is one of them ;)
