This model is a recreation of the “ponte girevole” (swinging/revolving bridge) by Leonardo da Vinci. It is a design included in the Atlantic Codex. It is an arched bridge that is supported with a single pillar in one of the banks, after which a counterweight of stones (I used some lead pieces as well as small stones) compensates for the length needed to reach the other shore.
Leonardos's original drawings of the swinging bridge. The Athlantic Code.
Leonardo’s Swinging bridge
Scale model of the “ponte girevole” (swinging/revolving bridge) by Leonardo da Vinvi
Leonardo da Vinci
width: 44, depth: 20, height: 16
For years I had dreamed of building any of Leonardo’s machines.
During a visit to la Galleria, in Firenze (Italy) I bought the wonderful book “Le machine di Leonardo”. The book shows documents from the Athlantic Code and is illustrated the original designs together with som perfect computer assisted recreations which I have used to make this scale model: Il ponte girevole. Enjoy it.
