Calling all pumpkin chuckers, wannabe marauders, and tinkerers of all ages! Flinging things and playing at defending your own castle has never been more fun. Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey—ancient artillery devices known commonly as catapults. Updated and improved instructions and diagrams illustrate how to build 10 authentic working model catapults, including an early Greek ballista, a Roman onager, and the apex of catapult technology, the English trebuchet. Additional projects include learning how to lash and make rope and how to construct and use a hand sling and a staff sling. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. The colorful history of siege warfare is explored through the stories of Alexander the Great and his battle of Tyre; Saladin, Richard the Lionheart, and the Third Crusade; pirate-turned-soldier Jon Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle. For the legions of Tolkien fans, budding backyard warriors, and engineering wizards, this book is a must-have.

An " enormously entertaining" (Smithsonian), " clever, subtle, and adroit" account (Wall Street Journal) of how the author and his friend constructed a medieval siege engine in a San Francisco backyard. " So funny that I could not put it down" (Los Angeles Times).

"In this delightful autofiction―the first book by Gainza, an Argentine art critic, to appear in English―a woman delivers pithy assessments of world–class painters along with glimpses of her life, braiding the two into an illuminating whole." ―The New York Times Book Review, Notable Book of the Year and Editors' Choice The narrator of Optic Nerve is an Argentinian woman whose obsession is art. The story of her life is the story of the paintings, and painters, who matter to her. Her intimate, digressive voice guides us through a gallery of moments that have touched her. In these pages, El Greco visits the Sistine Chapel and is appalled by Michelangelo’s bodies. The mystery of Rothko’s refusal to finish murals for the Seagram Building in New York is blended with the story of a hospital in which a prostitute walks the halls while the narrator’s husband receives chemotherapy. Alfred de Dreux visits Géricault’s workshop; Gustave Courbet’s devilish seascapes incite viewers “to have sex, or to eat an apple”; Picasso organizes a cruel banquet in Rousseau’s honor . . . All of these fascinating episodes in art history interact with the narrator’s life in Buenos Aires―her family and work; her loves and losses; her infatuations and disappointments. The effect is of a character refracted by environment, composed by the canvases she studies. Seductive and capricious, Optic Nerve marks the English–language debut of a major Argentinian writer. It is a book that captures, like no other, the mysterious connections between a work of art and the person who perceives it.

This text is a compilation of step-by-step instructions for how to build nine different types of catapults and trebuchets. Each set of instructions includes dimensional drawings of all wooden parts, lists of required hardware and sources, an abundance of photos, diagrams, and detailed descriptions of the assembly process.

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 readers get started in this fascinating hobby of harnessing the power and energy of simple and ancient machines, then using them to hurl all sorts of silly things into the air just to watch them splat.
