I’m thinking of building a trebuchet.
I loved playing Age of Empires II: The Age of Kings and pulling out the trebuchet, usually four or five trebuchets, in the Imperial Age and razing cities to the ground from long distances. I loved seeing the trebuchet deployed in the defense of Minas Tirith in The Return of the King (though I don’t quite see how Gondor’s trebuchets worked–they had no obvious counterweights). So when I saw William Gurstelle’s book, The Art of the Catapult, advertised in the Science Fiction Book Club flyer my interest in medieval warfare virtually mandated that I order the book.
(In that shipment I ordered another book, which I won’t name here, as someone’s Christmas present, but for the life of me I can’t remember for whom I ordered it.)
I’ve spent part of the afternoon studying the diagrams of ballistae, onagers, and trebuchets. There’s that big empty field next to my house, and wouldn’t that be ideal for setting up a medieval siege weapon?
