Blank verso, invisible before restoration
Catalogue links the sheet to water-lifting and diving devices
This side of the leaf is blank: the e-Leo transcription records it as devoid of writing or drawings and invisible before restoration, and the image shows only a bare, discoloured paper fragment with faint show-through. The Codex Atlanticus catalogue tags the sheet with studies of water-lifting engines, Archimedean screws, bailing pumps and diving apparatus, which belong to its drawn side. Nothing is inscribed on this side to describe.
