Blank leaf with reflection lines showing through
Verso noted as devoid of writing; the recto's radiating construction lines bleed through the paper
The transcription records this side as blank, invisible before restoration and carrying no writing or drawings of its own. Visible instead is show-through from the recto: a spray of faint straight lines radiating from a point near the centre-left of the sheet, the reflection construction seen from behind. The leaf is catalogued for geometrical and natural-philosophy content.

Radiating construction lines showing through from the recto
Though this side carries no writing of its own, a fan of faint straight lines converging on a single point near the centre-left shows through the paper. These are the recto's ray and construction lines seen in reverse.
