Sheet with small mechanical diagrams and untranscribed notes
Faint mirror-script and figures on a transmitted-light leaf
This transmitted-light image of folio 129r shows a full page densely covered with Leonardo's mirror-script, none of which is included in the bundle, together with several small diagrams. Among the figures are a spoked wheel or disc, small circles, and faint line drawings that read as balance-beams and hanging weights. No transcription accompanies the sheet, so the writing is left undescribed; the visible drawings sit within the mechanics notes that fill this stretch of the codex.

Small wheel and weight-line figures
Among the untranscribed text are faint diagrams including a spoked wheel or disc and slender line figures resembling a balance with suspended weights. Their labels and exact function cannot be read with confidence in the transmitted-light plate.
