All figures are based upon drawings by Leonardo unless otherwise indicated. The figures should not be regarded as reproductions of the original drawings but as diagrammatic transcriptions made for the purpose of illustrating a specific point or points. In some cases, where it seemed appropriate, the lines of the original drawings have been closely followed, while in others (particularly those of a geometrical nature) the diagrammatic intentions of the sketches have been clarified.
