The Book of the Elements of Machines

 

Leonardo recommends gears. Crank, pinion, the toothed wheel and rack. Also ratchet wheel, pulleys and pulley blocks, axles of all sorts. To animate the landscape: copy it. Find equilibrium in a bird’s flight. Joints and hinges resemble what they imitate. Crank to crankshaft. Flywheel. Spring. Study the leg joint, stand in a far field, use the ten offices of the eye. Cams. Levers of every kind. Chestnut, elm, oak and ilex. I am mirror writing with my left hand. Chains, belts, rotating airscrew, a study of light and shadow. The unwritten treatise on water. Anatomical aerodynamics sketched from a bird’s wing. Cantilevers, cadavers. Cold muscle flayed under the knife. Archetypal geometric forms. The mental discourse of paint layered image upon image. The heart is a furnace. It burns air. We will walk on water.
