Mechanical and hydraulic studies on a faint sheet
Catalogued as invisible before restoration; faint drawings and mirror-script text remain
The e-Leo caption records this side of folio 383 as invisible before restoration and devoid of writing and drawings, yet faint sketches and a block of mirror-script prose are now visible across the sheet. The upper zone carries faint studies of vertical shafts, a bracket and rectangular frames; a paragraph of untranscribed text fills the lower half. The Ambrosiana's classification links the sheet to geometry, the physics of why one element flees another, the behaviour of liquids, and the 'Doccia' at Vinci. None of this writing is transcribed here.

Faint shaft-and-frame sketches with untranscribed prose
The top of the sheet bears faint drawings of vertical shafts, a hinged bracket and rectangular frames, the kind of structural or mechanical members that recur in Leonardo's water-works studies. A block of mirror-script text runs beneath them. This writing is not included in the bundle and is left untranscribed.
